Guide to Image Classification & Object Detection

Computer vision, a driving force behind global AI development, has revolutionized various industries with its expanding range of tasks. From self-driving cars to medical image analysis and virtual reality, its capabilities seem endless. In this article, we'll explore two fundamental tasks in computer vision: image classification and object detection. Although often misunderstood, these tasks serve distinct purposes and are crucial to numerous AI applications.

The Magic of Computer Vision:

Enabling computers to "see" and understand images is a remarkable technological achievement. At the heart of this progress are image classification and object detection, which form the backbone of many AI applications, including gesture recognition and traffic sign detection.

Understanding the Nuances:

As we delve into the differences between image classification and object detection, we'll uncover their crucial roles in training robust models for enhanced machine vision. By grasping the nuances of these tasks, we can unlock the full potential of computer vision and drive innovation in AI development.

Key Factors to Consider:

Humans possess a unique ability to identify objects even in challenging situations, such as low lighting or various poses. In the realm of artificial intelligence, we strive to replicate this human accuracy in recognizing objects within images and videos.

Object detection and image classification are fundamental tasks in computer vision. With the right resources, computers can be effectively trained to excel at both object detection and classification. To better understand the differences between these tasks, let's discuss each one separately.

Image Classification:

Image classification involves identifying and categorizing the entire image based on the dominant object or feature present. For example, when given an image of a cat, an image classification model will categorize it as a "cat." Assigning a single label to an image from predefined categories is a straightforward task.

Key factors to consider in image classification:

Accuracy: Ensuring the model correctly identifies the main object in the image.

Speed: Fast classification is essential for real-time applications.

Dataset Quality: A diverse and high-quality dataset is crucial for training accurate models.

Object Detection:

Object detection, on the other hand, involves identifying and locating multiple objects within an image. This task is more complex as it requires the model to not only recognize various objects but also pinpoint their exact positions within the image using bounding boxes. For instance, in a street scene image, an object detection model can identify cars, pedestrians, traffic signs, and more, along with their respective locations.

Key factors to consider in object detection:

Precision: Accurate localization of multiple objects in an image.

Complexity: Handling various objects with different shapes, sizes, and orientations.

Performance: Balancing detection accuracy with computational efficiency, especially for real-time processing.

Differences Between Image Classification & Object Detection:

While image classification provides a simple and efficient way to categorize images, it is limited to identifying a single object per image. Object detection, however, offers a more comprehensive solution by identifying and localizing multiple objects within the same image, making it ideal for applications like autonomous driving, security surveillance, and medical imaging.

Similarities Between Image Classification & Object Detection:

Certainly! Here's the content presented in a table format highlighting the similarities between image classification and object detection:

By presenting the similarities in a tabular format, it's easier to grasp how both image classification and object detection share common technologies, challenges, and methodologies, despite their different objectives in the field of computer vision.

Practical Guide to Distinguishing Between Image Classification and Object Detection:

Building upon our prior discussion of image classification vs. object detection, let's delve into their practical significance and offer a comprehensive approach to solidify your basic knowledge about these fundamental computer vision techniques.

Image Classification:

Image classification involves assigning a predefined category to a visual data piece. Using a labeled dataset, an ML model is trained to predict the label for new images.

Single Label Classification: Assigns a single class label to data, like categorizing an object as a bird or a plane.

Multi-Label Classification: Assigns two or more class labels to data, useful for identifying multiple attributes within an image, such as tree species, animal types, and terrain in ecological research.

Practical Applications:

Digital asset management

AI content moderation

Product categorization in e-commerce

Object Detection:

Object detection has seen significant advancements, enabling real-time implementations on resource-constrained devices. It locates and identifies multiple objects within an image.

Future Research Focus:

Lightweight detection for edge devices

End-to-end pipelines for efficiency

Small object detection for population counting

3D object detection for autonomous driving

Video detection with improved spatial-temporal correlation

Cross-modality detection for accuracy enhancement

Open-world detection for unknown objects detection

Advanced Scenarios:

Combining classification and object detection models enhances subclassification based on attributes and enables more accurate identification of objects.

Additionally, services for data collection, preprocessing, scaling, monitoring, security, and efficient cloud deployment enhance both image classification and object detection capabilities.

Understanding these nuances helps in choosing the right approach for your computer vision tasks and maximizing the potential of AI solutions.

Summary

In summary, both object detection and image classification play crucial roles in computer vision. Understanding their distinctions and core elements allows us to harness these technologies effectively. At TagX, we excel in providing top-notch services for object detection, enhancing AI solutions to achieve human-like precision in identifying objects in images and videos.

Image Classification vs Object Detection

Image classification, object detection, object localization — all of these may be a tangled mess in your mind, and that's completely fine if you are new to these concepts. In reality, they are essential components of computer vision and image annotation, each with its own distinct nuances. Let's untangle the intricacies right away.We've already established that image classification refers to assigning a specific label to the entire image. On the other hand, object localization goes beyond classification and focuses on precisely identifying and localizing the main object or regions of interest in an image. By drawing bounding boxes around these objects, object localization provides detailed spatial information, allowing for more specific analysis.

Object detection on the other hand is the method of locating items within and image assigning labels to them, as opposed to image classification, which assigns a label to the entire picture. As the name implies, object detection recognizes the target items inside an image, labels them, and specifies their position. One of the most prominent tools to perform object detection is the “bounding box” which is used to indicate where a particular object is located on an image and what the label of that object is. Essentially, object detection combines image classification and object localization.

New evidence of organic material identified on Ceres, the inner solar system's most water-rich object after Earth

Six years ago, NASA's Dawn mission communicated with Earth for the last time, ending its exploration of Ceres and Vesta, the two largest bodies in the asteroid belt. Since then, Ceres —a water-rich dwarf planet showing signs of geological activity— has been at the center of intense debates about its origin and evolution.

Now, a study led by IAA-CSIC, using Dawn data and an innovative methodology, has identified 11 new regions suggesting the existence of an internal reservoir of organic materials in the dwarf planet. The results, published in The Planetary Science Journal, provide critical insights into the potential nature of this celestial body.

In 2017, the Dawn spacecraft detected organic compounds near the Ernutet crater in Ceres' northern hemisphere, sparking discussions about their origin. One leading hypothesis proposed an exogenous origin, suggesting these materials were delivered by recent impacts of organic-rich comets or asteroids.

This new research, however, focuses on a second possibility: that the organic material formed within Ceres and has been stored in a reservoir shielded from solar radiation.

"The significance of this discovery lies in the fact that, if these are endogenous materials, it would confirm the existence of internal energy sources that could support biological processes," explains Juan Luis Rizos, a researcher at the Instituto de Astrofísica de Andalucía (IAA-CSIC) and the lead author of the study.

A potential witness to the dawn of the solar system

With a diameter exceeding 930 kilometers, Ceres is the largest object in the main asteroid belt. This dwarf planet—which shares some characteristics with planets but doesn't meet all the criteria for planetary classification—is recognized as the most water-rich body in the inner solar system after Earth, placing it among the ocean worlds with potential astrobiological significance.

Additionally, due to its physical and chemical properties, Ceres is linked to a type of meteorite rich in carbon compounds: carbonaceous chondrites. These meteorites are considered remnants of the material that formed the solar system approximately 4.6 billion years ago.

"Ceres will play a key role in future space exploration. Its water, present as ice and possibly as liquid beneath the surface, makes it an intriguing location for resource exploration," says Rizos (IAA-CSIC). "In the context of space colonization, Ceres could serve as a stopover or resource base for future missions to Mars or beyond."

The ideal combination of high-quality resolutions

To explore the nature of these organic compounds, the study employed a novel approach, allowing for the detailed examination of Ceres' surface and the analysis of the distribution of organic materials at the highest possible resolution.

First, the team applied a Spectral Mixture Analysis (SMA) method—a technique used to interpret complex spectral data—to characterize the compounds in the Ernutet crater.

Using these results, they systematically scanned the rest of Ceres' surface with high spatial resolution images from the Dawn spacecraft's Framing Camera 2 (FC2). This instrument provided high-resolution spatial images but low spectral resolution. This approach led to the identification of eleven new regions with characteristics suggesting the presence of organic compounds.

Most of these areas are near the equatorial region of Ernutet, where they have been more exposed to solar radiation than the organic materials previously identified in the crater. Prolonged exposure to solar radiation and the solar wind likely explains the weaker signals detected, as these factors degrade the spectral features of organic materials over time.

Next, the researchers conducted an in-depth spectral analysis of the candidate regions using the Dawn spacecraft's VIR imaging spectrometer, which offers high spectral resolution, though at lower spatial resolution than the FC2 camera. The combination of data from both instruments was crucial for this discovery.

Among the candidates, a region between the Urvara and Yalode basins stood out with the strongest evidence for organic materials. In this area, the organic compounds are distributed within a geological unit formed by the ejection of material during the impacts that created these basins.

"These impacts were the most violent Ceres has experienced, so the material must originate from deeper regions than the material ejected from other basins or craters," clarifies Rizos (IAA-CSIC). "If the presence of organics is confirmed, their origin leaves little doubt that these compounds are endogenous materials."

Trends in incidence of COVID 19 based on performed Rapid Antigen Test by Piratheep kumar.R in Journal of Clinical Case Reports Medical Images and Health Sciences

Abstract

The COVID 19 outbreak represents a historically unprecedented pandemic, particularly dangerous and potentially lethal for elderly population. The biological differences in the immune systems between men and women exist which may impact our ability to fight an infection including SARS-2-CoV-2. Men tended to develop more symptomatic and serious disease than women, according to the clinical classification of severity. Age-related changes in the immune system are also different between sexes and there is a marked association between morbidity/mortality and advanced age in COVID-19. This is a single-center, retrospective, data oriented study performed at the private hospital, in Central Province, Sri Lanka. The data of the patients who performed the Rapid Antigen Test (RAT) to know whether they have infected by SARS-CoV-2 or not, were taken for analysis. Test performed date, age, sex, number of positive and negative cases, number of male and female patients were extracted. Finally the data were analyzed in simple statistical method according to the objective of the study. Totally 642 patients performed RAT within the period of one month from 11.08.2021 to 11.09.2021. Among them 426 (66.35%) are male and 216 (33.64%) are female. 20.4% (n=131) of male obtained positive result among the total male population (n=426). Likewise 11.4% (n=73) of female obtained positive result among the total male population (n=216).  Large number of positive cases was observed (34.89%) between the age group of 31-40 years in both sexes. The age group of 21-30 and 41-50 years also were shared the almost same percentage (17.13% & 17.75). The large number of positive male patients observed among the age group of 41-50 years. Almost same number of patients was observed in the age group of 21-30 and 31-40. The least number of positive cases (0.7% and 0.9%) observed almost in 0-10 and 81-90 years. When considering the females, large number of positive female patients observed among the age group of 31-40 years.

Key words: Rapid Antigen Test, Covid-19, SARS-CoV-2

Introduction

A rapid antigen test (RAT) or rapid antigen detection test (RADT), is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence of an antigen. It is used to detect SARS-CoV-2 that cause COVID-19. This test is one of the type of lateral flow tests that detect protein, differentiate it from other medical tests such as antibody tests or nucleic acid tests, of either laboratory or point-of-care types. Generally 5 to 30 minutes only will take to get result and, require minimal training or infrastructure, and cost effective (1).

Sri Lanka was extremely vulnerable to the spread of COVID-19 because of its thriving tourism industry and large expatriate population. Sri Lanka almost managed two waves of Covid-19 pandemic well, but has been facing difficulties to control the third wave. The Sri Lankan government has executed stern actions to control the disease including island-wide travel restrictions. The government has been working with its development partners to take necessary action to mobilize resources to respond to the health and economic challenges posed by the pandemic (2) (3).

The COVID 19 outbreak is dangerous and fatal for elderly population. Since the beginning of the actual SARS-CoV-2 outbreak there were an evident that older people were at higher risk to get the infection and develop a more severe with bad prognosis. The mean age of patients that died was 80 years. The majority of those who are infected, that have a self-limiting infection and do recover are younger. On the other hand, those who suffer with more severe disease require intensive care unit admission and finally pass away are older (4).

Sandoval.  M., et al mentioned that the number of patients who are affected by SARS-CoV-2 with more than 80 years of age is similar to that with 65–79 years. The mortality rate in very elderly was 37.5% and this percentage was significantly higher compared to that observed in elderly. Further their findings were suggested that the age is a fundamental risk factor for mortality (5).

Since February 2020, more than 27.7 million people in US have been diagnosed with Covid-19 (6). Rates of COVID-19 deaths have increased across the Southern US, among the Hispanic population, and among adults aged 25–44 years (7). Young adults are at increased risk of SARS-CoV-2 because of exposure in work, academic, and social settings. According to the several database of different health organizations young adult, aged 18-29, were confirmed Coid-19 (9).

Go to:Amid of coronavirus disease 2019 (Covid-19) pandemic, much emphasis was initially placed on the elderly or those who have preexisting health conditions such as obesity, hypertension, and diabetes as being at high risk of contracting and/or dying of Covid-19. But it is now becoming clear that being male is also a factor. The epidemiological findings reported across different parts of the world indicated higher morbidity and mortality in males than females. While it is still too early to determine why the gender gap is emerging, this article point to several possible factors such as higher expression of angiotensin-converting enzyme-2 (ACE 2; receptors for coronavirus) in male than female, sex-based immunological differences driven by sex hormone and X chromosome. Furthermore, a large part of this difference in number of deaths is caused by gender behavior (lifestyle), i.e., higher levels of smoking and drinking among men compared to women. Lastly, studies reported that women had more responsible attitude toward the Covid-19 pandemic than men. Irresponsible attitude among men reversibly affect their undertaking of preventive measures such as frequent handwashing, wearing of face mask, and stay at home orders.

The latest immunological study on the receptors for SARS-CoV-2 suggest that ACE2 receptors are responsible for SARS-CoV-2. According to the study by Lu and colleagues there are positive correlation of ACE2 expression and the infection of SARS-CoV (10). Based on the positive correlation between ACE 2 and coronavirus, different studies quantified the expression of ACE 2 proteins in human cells based on gender ethnicity and a study on the expression level and pattern of human ACE 2 using a single-cell RNA-sequencing analysis indicated that Asian males had higher expression of ACE 2 than female (11). Conversely, in establishing the expression of ACE 2 in the primary affected organ, a study conducted in Chinese population found that expression of ACE 2 in human lungs was extremely expressed in Asian male than female (12).

A study by Karnam and colleagues reveled that CD200-CD200R and sex are host factors that together determine the outcome of viral infection. Further a review on association between sex differences in immune responses stated that sex-based immunological differences contribute to variations in the susceptibility to infectious diseases and responses to vaccines in males and females (13). The concept of sex-based immunological differences driven by sex hormone and X chromosome has been well demonstrated via the animal study by Elgendy et al (14) (35). They were concluded the study that estrogen played big role in blocking some viral infection.

The biological differences in the immune systems between men and women may cause impact on fight for infection. Females are more resistant to infections than men and which mediated by certain factors including sex hormones. Further, women have more responsible attitude toward the Covid-19 pandemic than men such as frequent hand washing, wearing of face mask, and stay at home (15).

Most of the studies with Covid-19 patients indicate that males are mostly (more than 50%) affected than females (16) (17) (18). Although the deceased patients were significantly older than the patients who survived COVID-19, ages were comparable between males and females in both the deceased and the patients who survived (18).

A report in The Lancet and Global Health 5050 summary showed that sex-disaggregated data are essential to understanding the distribution of risk, infection and disease in the population, and the extent to which sex and gender affect clinical outcomes (19). The degree of outbreaks which affect men and women in different ways is an important to design the effective equitable policies and interventions (20). A systematic review and meta-analysis conducted to assess the sex difference in acquiring COVID-19 with 57 studies that revealed that the pooled prevalence of COVID-19 confirmed cases among men and women was 55% and 45% respectively (21). A study in Ontario, Canada showed that men were more likely to test positive (22) (23). In Pakistan 72% of COVID-19 cases were male (24). Moreover, the Global Health 5050 data showed that the number of COVID-19 confirmed cases and the death rate due to the disease are high among men in different countries. This might be because behavioral factors and roles which increase the risk of acquiring COVID-19 for men than women. (25) (26) (27).

Men mostly involved in several activities such as alcohol consumption, being involved in key activities during burial rites, and working in basic sectors and occupations that require them to continue being active, to work outside their homes and to interact with other people even during the containment phase. Therefore, men have increased level of exposure and high risk of getting COVID-19 (28) (29) (30).

Men tended to develop more symptomatic and serious disease than women, according to the clinical classification of severity (31). The same incidence also noticed during the previous coronavirus epidemics. Biological sex variation is said to be one of the reasons for the sex discrepancy in COVID-19 cases, severity and mortality (32) (33). Women are in general able to stand a strong immune response to infections and vaccinations (34).

The X chromosome is known to contain the largest number of immune-related genes in the whole genome. With their XX chromosome, women have a double copy of key immune genes compared with a single copy in XY in men. This showed that the reaction against infection would be contain both innate and adaptive immune response. Therefore the immune systems of females are generally more responsive than females and it indirectly reflects that women are able to challenge the coronavirus more effectively but this has not been proven (32).

Sex differences in the prevalence and outcomes of infectious diseases occur at all ages, with an overall higher burden of bacterial, viral, fungal and parasitic infections in human males (36) (37) (38) (39). The Hong Kong SARS-CoV-1 epidemic showed an age-adjusted relative mortality risk ratio of 1.62 (95% CI = 1.21, 2.16) for males (40). During the same outbreak in Singapore, male sex was associated with an odds ratio of 3.10 (95% CI = 1.64, 5.87; p ≤ 0.001) for ITU admission or death (41). The Saudi Arabian MERS outbreak in 2013 - 2014 exhibited a case fatality rate of 52% in men and 23% in women (42). Sex differences in both the innate and adaptive immune system have been previously reported and may account for the female advantage in COVID-19. Within the adaptive immune system, females have higher numbers of CD4+ T (43) (44) (45) (46) (47) (48) cells, more robust CD8+ T cell cytotoxic activity (49), and increased B cell production of immunoglobulin compared to males (43) (50). Female B cells also produce more antigen-specific IgG in response to TIV (51).

Age-related changes in the immune system are also different between sexes and there is a marked association between morbidity/mortality and advanced age in COVID-19 (52). For example, males show an age-related decline in B cells and a trend towards accelerated immune ageing. This may further contribute to the sex bias seen in COVID-19 (53).

Hence, this single center, retrospective, data oriented study performed to identify the gender age influences the RAT results and the rate of positive cases before and after the lockdown.

Methodology

This is a single-center, retrospective, data oriented study performed at the private hospital, Central Province, Sri Lanka. The data of the patients who performed the Rapid Antigen Test (RAT) from 11.08.2021to 11.0.2021 to know whether they have infected by SARS-CoV-2 or not, were taken for analysis. The authors developed a data extraction form on an Excel sheet and the following data from main data sheet. Test performed date, age, sex, number of positive and negative cases, number of female patients and number of male patients were extracted. Mistyping of data was resolved by crosschecking. Finally the data were analyzed in simple statistical method according to the objective of the study.

Results and discussion

Totally 642 patients performed RAT within the period of one month from 11.08.2021 to 11.09.2021. Among them 426 (66.35%) are male and 216 (33.64%) are female. Men mostly involved in several activities such as alcohol consumption, being involved in key activities during burial rites, and working in basic sectors and occupations that require them to continue being active, to work outside their homes and to interact with other people even during the containment phase. Therefore, men have increased level of exposure and high risk of getting COVID-19 (28) (29) (30). The present data descriptive study also were supported certain previous research findings.

The number of male patients got positive result in RAT among the total male patients who performed RAT on every day. According to that, 20.4% (n=131) of male obtained positive result among the total male population (n=426). Philip Goulder, professor of immunology at the University of Oxford stated that women’s immune response to the virus is stronger since they have two X chromosomes which is important when talk about the immune response against SARS-Cov-2. Because the protein by which viruses such as coronavirus are detected is fixed on the X chromosome. This is exactly looks like females have double protection compare to male. The present study also showed that large number of RAT positive cases were observed in males compare to females. Gender based lifestyle would have been another possibility for large number of males got positive in RATs. There are important behavioral differences between the sexes according to certain previous research findings (54).

Shows that the number of female patients got positive result in RAT among the total female patients who performed RAT on every day. According to that, 11.4% (n=73) of female obtained positive result among the total male population (n=216).

The relations between the number of positive cases before and after the lockdown. The lockdown declared by the tenth day from the initial day when the data was taken for analysis. The red vertical line differentiates the period as two such as before and after the lockdown. Though there was no decline observed as soon as immediately considerable decline was observed after the 21 days of onset of lockdown. Staying at home, avoiding physical contacts, and avoiding exposure in crowded areas are the best way to prevent the spread of Covid – 19 (54). However the significant decline would be able to see after three weeks only from the date of lockdown since the incubation period of SARS-CoV-2 is 14-21 days. The continuous study should be conducted in order to prove it. However the molecular mechanism of COVID-19 transmission pathway from human to human is still not resolved, the common transmission of respiratory diseases is droplet sprinkling. In this type of spreading, a sick person is exposed to this microbe to people around him by coughing or sneezing. Only the way to prevent these kind of respiratory diseases might be prevent the people to make close contact (54) (55). Approximately 214 countries reported the number of confirmed COVID-19 cases (56). Countries including Sri Lanka have taken very serious constraints such as announced vacation for schools, allowed the employers to work from home and etc. to slow down the COVID 19 outbreak. The lockdown days differ by countries. Countries have set the days when the lockdown started and ended according to the COVID-19 effect on their public. Some countries have extended the lockdown by many days due to COVID-19 continues its influence intensely on the public (57) (58).

The incidence of Covid-19 and age group. Accordingly large number was observed (34.89%) between the age group of 31-40 years in both sexes. The age group of 21-30 and 41-50 years also were shared the almost same percentage (17.13% & 17.75). A study provides evidence that the growing COVID-19 epidemics in the US in 2020 have been driven by adults aged 20 to 49 and, in particular, adults aged 35 to 49, before and after school reopening (59). However many researches pointed out that adults over the age of 60 years are more susceptible to infection since their immune system gradually loses its resiliency.

The relations between the positive number of male & female patients and the age group of total patients. According to that the large number of positive male patients observed among the age group of 41-50 years. Almost same number of patients was observed in the age group of 21-30 and 31-40. The least number of positive cases (0.7% and 0.9%) observed almost in 0-10 and 81-90 years. When considering the females, large number of positive female patients observed among the age group of 31-40 years. In USA Ministry of Health has reported 444 921 COVID-19 cases and 15 756 deaths as of August 31. For men, most reported cases were persons aged 30–39 years (22.7%), followed by 20–29 year-olds (20.1%) and 40–49 year-olds (17.1%). Most reported deaths were seniors, especially 70–79 year-olds (29.5%), followed by those aged 80 years and older (29.2%), and 60–69 year-olds (22.8%). Also found a similar pattern for women, except that most deaths were reported among women aged 80 years and older (44.4%) (60).

Conclusion

The present study showed that the male are mostly got positive in RAT test than female. Further comparing the old age young age group in both sexes were noticed as positive in RAT. Moreover there were no relationship observed before and after the lockdown and trend of Covid-19

 The limitations of the study

This study has several limitations.

Only 1 hospital was studied.

More than the absence of specific data on mobility patterns or transportation, detail of recovery, detail of mortality etc.

The COVID-19 pandemic is still ongoing so statistical analysis should continue. There are conflicting statements regarding lockdown by countries on COVID-19.

The effect of the lockdown caused by the COVID-19 pandemic on human health may be the subject of future work.

Classify images with the Custom Vision Service

Image classification is a technique where the object in an image is being classified

You need data that consists of features and labels

Digital images are made up of an array of pixel values. These are used as features to train the model based on known image classes

Most modern image classification solutions are based on deep learning techniques.

They use Convolutional neural Networks (CNNS) to uncover patterns in the pixels to a particular class.

Model Training

To train a model you must upload images to a training resource and label them with class labels

Custom Vision Portal is the application where the training occurs in

Additionally it can use Custom Vision service programming languages-specific SDKs

Model Evaluation

Precision - percentage of the class predictions made by the model that are correct

Recall - percentage of the class predictions the model identified correctly

Average Precision - Overall metric using precision and recall

Detect objects in images with the Custom Vision service

Requires training the object detection model, you must tag the classes and bounding box coordinates in a training set of images

This can be time consuming, but the Custom Vision portal makes this straightforward

The portal will suggest areas of the image where discrete objects are detected and you can add a class label

It also has Smart Tagging, where it suggests classes and bounding boxes to use for training

Precision - percentage of the class predictions made by the model that are correct

Recall - percentage of the class predictions the model identified correctly

Mean Average Precision (mAP) - Overall metric using precision and recall across all classes

Detect and analyze faces with the Face Service

Involves identifying regions of an image that contain a human face

It returns a bounding box that form a rectangle around the face

Moving beyond face detection, some algorithms return other information like facial landmarks (nose, eyes, eyebrows, lips, etc)

Facial landmarks can be used as features to train a model.

Another application of facial analysis. Used to train ML models to identify known individuals from their facial features.

More generally known as facial recognition

Requires multiple images of the person you want to recognize

Security - to build security applications and is used more and more no mobile devices

Social Media - use to automatically tag people and friends in photos.

Intelligent Monitoring - to monitor a persons face, for example when they are driving to determine where they are looking

Advertising - analyze faces in an image to direct advertisements to an appropriate demographic audience

Missing persons - use public camera systems with facial recognition to identify if a person is a missing person

Identity validation - use at port of entry kiosks to allow access/special entry permit

Blur - how blurry the face is

Exposure - aspects such as underexposed or over exposed and applies to the face in the image not overall image exposure

Glasses - if the person has glasses on

Head pose - face orientation in 3d space

Noise - visual noise in the image.

Occlusion - determines if any objects cover the face

Read text with the Computer Vision service

Submit an image to the API and get an operation ID

Use the operation ID to check status

When it’s completed get the result.

Microsoft Azure AI Fundamentals: Explore decision support

Monitoring blood pressure

Evaluating mean tie between failures for hardware products

Part of the decision services category

Can be used with REST API

Sensitivity parameter is from 1 to 99

Anomalies are values outside expected values or ranges of values

The sensitivity boundary can be configured when making the API call

It uses a boundary, set as a sensitivity value, to create the upper and lower boundaries for anomaly detection

Calculated using concepts known as expectedValue, upperMargin, lowerMargin

If a value exceeds either boundary, then it is an anomaly

upperBoundary = expectedValue + (100-marginScale) * upperMargin

The service accepts data in JSON format.

It supports a maximum of 8640 data points. Break this down into smaller requests to improve the performance.

When to use Anomaly Detector

Process the algorithm against an entire set of data at one time

It creates a model based on your complete data set and the finds anomalies

Uses streaming data by comparing previously seen dat points to the last datapoint to determine if your latest one is an anomaly.

Model is created using the data points you send and determines if the current point is an anomaly.

Microsoft Azure AI Fundamentals: Explore natural language processing

Analyze Text with the Language Service

Used to describe solutions that involve extracting information from large volumes of unstructured data.

Analyzing text is a process to evaluate different aspects of a document or phrase, to gain insights about that text.

Text Analytics Techniques

Interpret words like “power”, “powered”, and “powerful” as the same word.

Convert to tree like structures (Noun phrases)

Often used for sentiment analysis

Determine the language of a document or text

Perform sentiment analysis (positive or negative)

Extract key phrases from text to indicate key talking points

Identify and categorize entities (places, people, organizations, etc)

Get started with Text analysis

Language name

ISO 6391 language code

Score as a level of confidence n the language returned.

Evaluates text to return a sentiment score and labels for each sentence

Useful for detecting positive or negative sentiment

Classification is between 0 to 1 with 1 being most positive

A score of 0.5 is indeterminate sentiment.

The phrase doesn’t have sufficient information to determine the sentiment.

Mixing language content with the language you tell it will return 0.5 also

Key Phrase extraction

Used to determine the main talking points of a text or a document

Depending on the volume this can take longer, so you can use the key phrase extraction capabilities of the Language Service to summarize main points.

Key phrase extraction can provide context about the document or text

Entity Recognition

Person

Location

OrganizationQuantity

DateTime

URL

Email

US-based phone number

IP address

Recognize and Synthesize Speech

Acoustic model - converts audio signal to phonemes (representation of specific sounds)

Language model - maps the phonemes to words using a statistical algorithm to predict the most probably sequence of words based on the phonemes

ability to generate spoken output

Usually converting text to speech

This process tokenizes the set to break it down into individual words, assign phonetic sounds to each word

It then breaks the phonetic transcription to prosodic units to create phonemes for the audio

Get started with speech on Azure

Use this for demos, presentations, or scenarios where a person is speaking

In real time it can translate to many lunges as it processes

Audio files with Shared access signature (SAS) URI can be used and results are received asynchronously.

Jobs will start executing within minutes, but no estimate is provided for when the job changes to running state

Used to convert text to speech

Voices can be selected that will vocalize the text

Custom voices can be developed

Voices are trained using neural networks to overcome limitations in speech synthesis with regards to intonation.

Translate Text and Speech

Where each word is translated to the corresponding word in the target language

This approach has issues. For example, a direct word to word translation may not exist or the literal translation may not be the correct meaning of the phrase

Machine learning has to also understand the semantic context of the translation.

This provides more accurate translation of the input phrase or phrases

Grammar, formal versus informal, colloquialism all need to be considered

Text and speech translation

Profanity filtering - remove or do not translate profamity

Selective translation - tag content that isn’t to be translated (brand names, code names, etc)

Speech to text - transcribe speech from an audio source to text format.

Text to speech - used to generate spoken audio from a text source

Speech translation - translate speech in one language to text or speech in another

Create a language model with Conversational language Understanding

A None intent exists.

This should be used when no intent has been identified and should provide a message to a user.

Getting started with Conversational Language Understanding

Authoring the model - Defining entities, intents, and utterances to use to train the model

Entity Prediction - using the model after it is published.

Define intents based on actions a user would want to perform

Each intent should include a variety of utterances as examples of how a user may express the intent

If the intent can be applied to multiple entities, include sample utterances for each potential entity.

Machine-Learned - learned by the model during training from context in the sample utterances you provide

List - Defined as a hierarchy of lists and sublists

RegEx - regular expression patterns

Pattern.any - entities used with patterns to define complex entities that may be hard to extract from sample utterances

After intents and entities are created you train the model.

Training is the process of using your sample utterances to teach the model to match natural language expressions that a user may say to probable intents and entities.

Training and testing are iterative processes

If the model does not match correctly, you create more utterances, retrain, and test.

When results are satisfactory, you can publish the model.

Client applications can use the model by using and endpoint for the prediction resource

Build a bot with the Language Service and Azure Bot Service

Knowledge base of question and answer pairs. Usually some built-in natural language processing model to enable questions and can understand the semantic meaning

Bot service - to provide an interface to the knowledge base through one or more channels

Microsoft Azure AI Fundamentals: Explore knowledge mining

Used to describe solutions that involve extracting information from large volumes of unstructured data.

It has a services in Cognitive services to create a user-managed index.

The index can b meant for internal use only or shared with the public.

It can use other Cognitive Services capabilities to extract the information

What is Azure Cognitive Search?

Provides a programmable search engine build on Apache Lucene

Highly available platform with 99.9% uptime SLA for cloud and on-premise assets

Data from any source - accepts data form any source provided in JSON format with auto crawling support for selected data sources in Azure

Identify elements of a search solution

Folders with files,

Text in a database

Etc

Use a skillset to Define an enrichment pipeline

Key Phrase Extraction - uses a pre-trained model to detect important phrases based on term placement, linguistic rules, proximity to terms

Text Translation - pre-trained model to translate the input text into various languages for normalization or localization use cases

Image Analysis Skills - uses an image detection algorithm to identify the content of an image an generate a text description

Optical Character Recognition Skills - extract printed or handwritten text from images, photos, videos

Understand indexes

Index schema - index includes a definition of the structure of the data in the documents to read.

Index attributes - Each field in a document the index stores its name, the data type, supported behaviors (searchable, sortable, etc)

Best indexes use only the features that are required/needed

Use an indexer to build an index

Push method - JSON data is pushed into a search index via a REST API or a .NET SDK. Most flexible and with least restrictions

Pull method - Search service indexer pulls from popular Azure data sources and if necessary exports the Tinto JSON if its not already in that format

Use the pull method to load data with an indexer

Azure Cognitive search’s indexer is a crawler that extracts searchable text and metadata form an external Azure data source an populates a search index using field-to-field mapping between the data and the index.

Data import monitoring and verification

Indexers only import new or updated documents. It is normal to see zero documents indexed

Health information is displayed in a dashboard.

You can monitor the progress of the indexing

Making changes to an index

You need to drop and recreate indexes if you need to make changes to the field definitions

An approach to update your index without impacting your users is to create a new index with a new name

After importing data, switch to the new index.

Persist enriched data in a knowledge store

A knowledge store is persistent storage of enriched content.

The knowledge store is to store the data generated from Ai enrichment in a container.

New Post has been published on https://thedigitalinsider.com/transformers-and-beyond-rethinking-ai-architectures-for-specialized-tasks/

Transformers and Beyond: Rethinking AI Architectures for Specialized Tasks

In 2017, a significant change reshaped Artificial Intelligence (AI). A paper titled Attention Is All You Need introduced transformers. Initially developed to enhance language translation, these models have evolved into a robust framework that excels in sequence modeling, enabling unprecedented efficiency and versatility across various applications. Today, transformers are not just a tool for natural language processing; they are the reason for many advancements in fields as diverse as biology, healthcare, robotics, and finance.

What began as a method for improving how machines understand and generate human language has now become a catalyst for solving complex problems that have persisted for decades. The adaptability of transformers is remarkable; their self-attention architecture allows them to process and learn from data in ways that traditional models cannot. This capability has led to innovations that have entirely transformed the AI domain.

Initially, transformers excelled in language tasks such as translation, summarization, and question-answering. Models like BERT and GPT took language understanding to new depths by grasping the context of words more effectively. ChatGPT, for instance, revolutionized conversational AI, transforming customer service and content creation.

As these models advanced, they tackled more complex challenges, including multi-turn conversations and understanding less commonly used languages. The development of models like GPT-4, which integrates both text and image processing, shows the growing capabilities of transformers. This evolution has broadened their application and enabled them to perform specialized tasks and innovations across various industries.

With industries increasingly adopting transformer models, these models are now being used for more specific purposes. This trend improves efficiency and addresses issues like bias and fairness while emphasizing the sustainable use of these technologies. The future of AI with transformers is about refining their abilities and applying them responsibly.

Transformers in Diverse Applications Beyond NLP

The adaptability of transformers has extended their use well beyond natural language processing. Vision Transformers (ViTs) have significantly advanced computer vision by using attention mechanisms instead of the traditional convolutional layers. This change has allowed ViTs to outperform Convolutional Neural Networks (CNNs) in image classification and object detection tasks. They are now applied in areas like autonomous vehicles, facial recognition systems, and augmented reality.

Transformers have also found critical applications in healthcare. They are improving diagnostic imaging by enhancing the detection of diseases in X-rays and MRIs. A significant achievement is AlphaFold, a transformer-based model developed by DeepMind, which solved the complex problem of predicting protein structures. This breakthrough has accelerated drug discovery and bioinformatics, aiding vaccine development and leading to personalized treatments, including cancer therapies.

In robotics, transformers are improving decision-making and motion planning. Tesla’s AI team uses transformer models in their self-driving systems to analyze complex driving situations in real-time. In finance, transformers help with fraud detection and market prediction by rapidly processing large datasets. Additionally, they are being used in autonomous drones for agriculture and logistics, demonstrating their effectiveness in dynamic and real-time scenarios. These examples highlight the role of transformers in advancing specialized tasks across various industries.

Why Transformers Excel in Specialized Tasks

Transformers’ core strengths make them suitable for diverse applications. Scalability enables them to handle massive datasets, making them ideal for tasks that require extensive computation. Their parallelism, enabled by the self-attention mechanism, ensures faster processing than sequential models like Recurrent Neural Networks (RNNs). For instance, transformers’ ability to process data in parallel has been critical in time-sensitive applications like real-time video analysis, where processing speed directly impacts outcomes, such as in surveillance or emergency response systems.

Transfer learning further enhances their versatility. Pretrained models such as GPT-3 or ViT can be fine-tuned for domain-specific needs, significantly reducing the resources required for training. This adaptability allows developers to reuse existing models for new applications, saving time and computational resources. For example, Hugging Face’s transformers library provides plenty of pre-trained models that researchers have adapted for niche fields like legal document summarization and agricultural crop analysis.

Their architecture’s adaptability also enables transitions between modalities, from text to images, sequences, and even genomic data. Genome sequencing and analysis, powered by transformer architectures, have enhanced precision in identifying genetic mutations linked to hereditary diseases, underlining their utility in healthcare.

Rethinking AI Architectures for the Future

As transformers extend their reach, the AI community reimagines architectural design to maximize efficiency and specialization. Emerging models like Linformer and Big Bird address computational bottlenecks by optimizing memory usage. These advancements ensure that transformers remain scalable and accessible as their applications grow. Linformer, for example, reduces the quadratic complexity of standard transformers, making it feasible to process longer sequences at a fraction of the cost.

Hybrid approaches are also gaining popularity, combining transformers with symbolic AI or other architectures. These models excel in tasks requiring both deep learning and structured reasoning. For instance, hybrid systems are used in legal document analysis, where transformers extract context while symbolic systems ensure adherence to regulatory frameworks. This combination bridges the unstructured and structured data gap, enabling more holistic AI solutions.

Specialized transformers tailored for specific industries are also available. Healthcare-specific models like PathFormer could revolutionize predictive diagnostics by analyzing pathology slides with unprecedented accuracy. Similarly, climate-focused transformers enhance environmental modeling, predicting weather patterns or simulating climate change scenarios. Open-source frameworks like Hugging Face are pivotal in democratizing access to these technologies, enabling smaller organizations to leverage cutting-edge AI without prohibitive costs.

Challenges and Barriers to Expanding Transformers

While innovations like OpenAI’s sparse attention mechanisms have helped reduce the computational burden, making these models more accessible, the overall resource demands still pose a barrier to widespread adoption.

Data dependency is another hurdle. Transformers require vast, high-quality datasets, which are not always available in specialized domains. Addressing this scarcity often involves synthetic data generation or transfer learning, but these solutions are not always reliable. New approaches, such as data augmentation and federated learning, are emerging to help, but they come with challenges. In healthcare, for instance, generating synthetic datasets that accurately reflect real-world diversity while protecting patient privacy remains a challenging problem.

Another challenge is the ethical implications of transformers. These models can unintentionally amplify biases in the data they are trained on. This can lead to unfair and discriminatory outcomes

in sensitive areas like hiring or law enforcement.

The integration of transformers with quantum computing could further enhance scalability and efficiency. Quantum transformers may enable breakthroughs in cryptography and drug synthesis, where computational demands are exceptionally high. For example, IBM’s work on combining quantum computing with AI already shows promise in solving optimization problems previously deemed intractable. As models become more accessible, cross-domain adaptability will likely become the norm, driving innovation in fields yet to explore the potential of AI.

The Bottom Line

Transformers have genuinely changed the game in AI, going far beyond their original role in language processing. Today, they are significantly impacting healthcare, robotics, and finance, solving problems that once seemed impossible. Their ability to handle complex tasks, process large amounts of data, and work in real-time is opening up new possibilities across industries. But with all this progress, challenges remain—like the need for quality data and the risk of bias.

As we move forward, we must continue improving these technologies while also considering their ethical and environmental impact. By embracing new approaches and combining them with emerging technologies, we can ensure that transformers help us build a future where AI benefits everyone.
