The Role of Semantic Layers in Self-Service BI

New Post has been published on https://thedigitalinsider.com/the-role-of-semantic-layers-in-self-service-bi/

The Role of Semantic Layers in Self-Service BI

As organizational data grows, its complexity also increases. These data complexities become a significant challenge for business users. Traditional data management approaches struggle to manage these data complexities, so advanced data management methods are required to process them. This is where semantic layers come in.

A semantic layer serves as a bridge between data infrastructure and business users. Semantic layers ensure data consistency and establish the relationships between data entities to simplify data processing. This, in turn, empowers business users with self-service business intelligence (BI), allowing them to make informed decisions without relying on IT teams.

The demand for self-service BI is growing quickly. In fact, the global self-service BI market was valued at USD 5.71 billion in 2023, and projections show it will expand to USD 27.32 billion by 2032.

This article will explain what a semantic layer is, why businesses need one, and how it enables self-service business intelligence.

What Is a Semantic Layer?

A semantic layer is a key component in data management infrastructure. It serves as the “top” or abstraction layer of a data warehouse or lakehouse, designed to simplify the complexities. Unlike a traditional data model, a semantic layer provides a business-oriented view of the data. It supports autonomous report development, analysis, and dashboards by business users.

Semantic layers enable businesses to:

Get deeper insights

Make informed decisions

Improve operational efficiency

Improve customer experience

Users can easily access the data with a semantic layer without worrying about the technical areas. There are many kinds of semantic layers, each tailored for a specific use case. A semantic layer also promotes data governance by providing data dictionaries, enabling data relationships, and ensuring data compliance.

Now that we understand semantic layers let’s see how they are the foundation of self-service business intelligence.

The Role of Semantic Layers in Self-Service BI

Semantic layers simplify data access and play a critical role in maintaining data integrity and governance. A semantic layer is a key enabler for self-service business intelligence across organizations. Let’s discuss some key benefits of semantic layers in self-service BI.

Simplified Data Access

Semantic layers translate technical data structures into business-friendly terms. This makes it easier for non-technical users to navigate and analyze data independently. Semantic models empower business users to uncover insights quickly and make data-driven decisions without relying on IT teams by offering an intuitive interface.

Empowering Business Users

With well-organized and accessible data, business users can create their own reports and dashboards, reducing reliance on IT. This self-service approach fosters informed decision-making and promotes a more agile business environment.

Improving Data Quality & Consistency

Semantic layers help maintain data accuracy, which leads to the following:

Real-time data validation

Standardized metrics

Accurate calculations

This data reliability enhances decision-making and improves collaboration. It also ensures that all the stakeholders are aligned on the same datasets.

Accelerate Time to Insight

Integrating a semantic layer into the infrastructure improves data accuracy and speeds up analysis. Organizations can quickly respond to market changes with reliable data, improving time-to-market and decision-making. This agility allows businesses to stay competitive by making quicker, data-driven adjustments in response to shifting market conditions.

Foster Collaboration and Knowledge Sharing

Rapid access to consistent insights and standardized metrics helps break down data silos and encourages cross-functional collaboration. Teams can share reports quickly, enhancing knowledge sharing across the organization. This collaboration leads to a more unified approach to problem-solving, with diverse teams contributing to a holistic view of the data.

Why Modern Businesses Need Semantic Layers

As previously mentioned, semantic layers help democratize data and eliminate ambiguity, fostering trust across the organization. Businesses looking to stay competitive are already embracing the semantic layer as a core enabler. A solid data management strategy, powered by a semantic layer, streamlines operations and supports sustainable growth.

Without a semantic layer, businesses may struggle with several challenges in effectively using their data, including:

Data Consistency & Quality Issues: Inconsistent data definitions and inaccuracies lead to data quality issues. This can be a nightmare for reliable insights. Businesses can avoid data quality issues by integrating a robust semantic layer in their data operations.

Data Silos: Data silos are a common issue where data is stored in isolated repositories and becomes ineffective. According to a report from S&P Global, the percentage of organizations affected by data silos varies. Estimates range from 39% to 82%. This results in lost revenue and wasted time.

Time-Consuming Processes: Extracting data manually is labor intensive because it involves extensive cross-functional collaboration. This leads to lost revenue and wasted time. Semantic layers can save this valuable time by categorizing the data and ensuring all the necessary means to access data.

The Future of Semantic Layers and Self-service Business Intelligence

Semantic layers are becoming essential for improving productivity. They make data easier to access and understand and help organizations quickly gain consistent, actionable insights.

As self-service BI adoption grows, semantic layers are evolving. In the future, they will be integrated directly into data warehouses, not tied to a specific BI tool. This change will make data more accessible and allow systems to work together more smoothly.

Semantic layers will streamline data access and support faster, smarter decisions. Their growth will help organizations stay agile and scale efficiently.

4 Biggest Risks of Non-Compliance With Data Privacy Regulations

Not complying with data privacy laws can jeopardize an organization’s cybersecurity, finances, reputation, and more.

Data Compliance is non-negotiable. Here are the risks of non-compliance

On Dec. 9, 2022, an important data privacy compliance deadline will pass for organizations that process U.S. consumers’ financial data. Under the Gramm-Leach-Bliley Act (GLBA)’s updated Safeguards Rule, organizations have until that day to comply with a series of data security practices that the landmark U.S. financial data privacy law has mandated, which include:

Releasing periodic reports to boards of directors and governing bodies

Instituting secure software development practices

Identifying and managing data based on risk

Implementing and reviewing data access controls

Encrypting data both in transit and at rest

Establishing secure procedures for disposing data

The GLBA is just one of many regulations across the globe with substantial privacy protections— a group that includes the European Union’s General Data Protection Regulation (GDPR), Brazil’s General Data Protection Law (LGPD), and the United States’ Health Insurance Portability and Accountability Act (HIPAA). These laws mandate that organizations within their jurisdiction employ effective data privacy practices to protect personally identifiable information (PII), or what the Safeguards Rule calls non-public personal information (NPI).

The stakes for data privacy compliance are high, as non-compliance can result in devastating consequences. Organizations can expect to face four major risks for non-compliance with data privacy laws: inadequate cybersecurity, expensive fines, high individual penalties, and reputational damage.

The Compliance (Cyber)Security Blanket

Compliance and data security go hand-in-hand— if an organization’s systems don’t comply with data privacy standards, there’s a good chance that its data security could be lacking. After all, a major component of data privacy on your compliance is ensuring that consumers’ data is safe from the hands of bad actors who could use the data nefariously.

For instance, the GLBA requires financial institutions to, “protect against any reasonably anticipated threats or hazards” as well as “unauthorized access to, or use of,” customers’ data. The Federal Financial Institutions Examination Council, which audits financial institutions, dictates that these institutions should use strong encryption and key management practices.

These practices, of course, improve compliance and security alike. So, even if your organization doesn’t get slapped with a data privacy lawsuit, non-compliance with data privacy regulations reflects poor data controls, a significant liability for your organization.

Non-Compliance Fines Aren’t Fine

If your organization violates a data privacy law, a punitive fine is almost guaranteed. The severity of fines cover a wide spectrum. For instance, every GLBA violation carries a fine of up to $100,000, while LGPD infractions carry a financial penalty of up to 2 percent of the sanctioned organization’s gross revenue, with a maximum fine of 50 million Brazilian Reals (about $9.7 million).

GDPR fines are even more grave— every GDPR violation can cost up to 4 percent of a company’s annual global revenues or €20 million (about $22 million)— whichever is highest. So far, Amazon Europe Core S.a.r.l. incurred the largest-ever GDPR fine when the Luxembourg National Commission for Data Protection levied a whopping $746 million fine on the technology giant for infringements related to Amazon’s advertising targeting system. Even moderate GDPR fines can exceed $10 million.

The Big House Awaits

When a data privacy law is broken, the organization may not be the only party held liable (if at all). While it varies case-by-case, employees within an infringing organization are sometimes penalized, as well.

These penalties can include individual fines and jail time— and like fines, they encompass a wide spectrum of severity. For instance, one individual who violated the U.K.’s Data Protection Act (DPA) in 2018 by stealing and selling customer records to rogue organizations incurred a 6- month prison sentence. Individual penalties under GLBA, meanwhile, are much higher—each violation of the Act can result in fines of up to $10,000 for directors and officers, license revocations, and up to five years of imprisonment.

The new Safeguards Rule requires covered entities to report annually to their boards of directors, effectively putting the protection of PII/NPI directly onto board agendas. So, while prison sentences for GLBA non-compliance are rare, accountable organizations’ board members in particular should be concerned with upholding the interests of their stakeholders via compliance.

Your Reputation Precedes You

The penalties and gravity of a cybersecurity breach that a noncompliant organization experiences can, of course, be measured. Less quantifiable though, is the reputational harm that a non-compliance lawsuit can inflict on organizations. Today’s omnipresent digital media presence ensures that word travels far and fast when organizations break the law— and as Warren Buffett famously said, “it takes 20 years to build a reputation and five minutes to ruin it.”

Reputational damage that an organization suffers as a result of any kind of lawsuit can manifest in two ways, as one business and commercial law firm notes. On the one hand, a lawsuit can hurt the organization’s reputation with the public— yet on the other hand, it can also dissuade companies from doing business with the defendant organization. A data privacy lawsuit naturally implies that an organization is either inept or apathetic in handling consumers’ data, so it could easily inflict both kinds of reputational damage.

Alliance With Compliance

The updated GLBA Safeguards Rule confirms two truths for accountable organizations. First, data privacy is a constantly evolving practice. And second, organizations cannot rest on their laurels when bringing their practices into compliance with these laws due to their evolving nature. Carrying out the necessary due diligence to ensure compliance with updated regulations is far less severe than risking penalties for noncompliance. The December 9 deadline is fast approaching. Delphix helps many banks and other covered organizations ensure compliance with a variety of data privacy-related regulations, including the GLBA Safeguards Rule, while also bolstering data security.

Seems that EA is now allegedly accused of a mayor privacy violation, having used tracking tools on The Sims FreePlay app to secretly gather and transmit players’ personal information to Facebook for advertising purposes. This data potentially includes unique Facebook IDs, which can be used to match players’ in-game activities to their individual Facebook profiles. Attorneys suspect that these potential data-sharing practices may violate a federal privacy law and are now gathering players to take action.

So, there are at least two class action against EA, because it seems to collect data from players using the Meta Pixel software to harness data from players and sell it to the Meta company, who owns Instagram, Facebook and other social networks.

It would be interesting to learn if this allegations are true and how this would be seen in the eyes of GDPR, European Regulation 679/2016, which allows the processing of personal data only with consent given by the data subjects and also in the context of (online) games.

Consent in the context of the GDPR must be understood as an unambiguous indication of an informed and freely given choice by the data subject, relating to specific processing activities. The burden of proof that these criteria are fulfilled falls upon the controller (i.e., the game developer).

Google Play list the privacy condition of EA for its games, including The Sims Freeplay. Basically EA claims to use players data only to give them "better game experience", which seems vague but not less legit. The only less transparent thing I noticed is that the instructions to opt out of targeted marketing of in-game ads are in English and not in Italian: downloading the game, players allows EA to share their account information with third-party partners to customize advertising experience, which is basically all app developers do, but it's weird that the instruction to opt out doesn't have been translated at all!

This is not the first time EA is accused of, well, unethical commercial practice, since EA has been sentenced to pay fines by Austrian (2023) and Belgian (2018) civil court, because their FIFA loot boxes violated local gambling laws.

Moreover, it's important to notice that in January 2023, the European Parliament adopted a report calling for harmonized EU rules to achieve better player protection in the online video game sector.

The Parliament called for greater transparency from developers about in-game purchases: player should be aware of the type of content before starting to play and during the game. Also, players should be informed on the probabilities in loot box mechanisms, including information in plain language about what algorithms are devised to achieve.

The Parliament further stressed that the proposed legislation should assess whether an obligation to disable in-game payments and loot boxes mechanisms by default or a ban on paid loot boxes should be proposed to protect minors, avoid the fragmentation of the single market and ensure that consumers benefit from the same level of protection, no matter of their place of residence.

The Parliament highlighted problematic practices, including exploiting cognitive biases and vulnerabilities of consumers through deceptive design and marketing, using layers of virtual currencies to mask/distort real-world monetary costs, and targeting loot boxes and manipulative practices towards minors.

A Full Guide to Fine-Tuning Large Language Models

New Post has been published on https://thedigitalinsider.com/a-full-guide-to-fine-tuning-large-language-models/

A Full Guide to Fine-Tuning Large Language Models

Large language models (LLMs) like GPT-4, LaMDA, PaLM, and others have taken the world by storm with their remarkable ability to understand and generate human-like text on a vast range of topics. These models are pre-trained on massive datasets comprising billions of words from the internet, books, and other sources.

This pre-training phase imbues the models with extensive general knowledge about language, topics, reasoning abilities, and even certain biases present in the training data. However, despite their incredible breadth, these pre-trained LLMs lack specialized expertise for specific domains or tasks.

This is where fine-tuning comes in – the process of adapting a pre-trained LLM to excel at a particular application or use-case. By further training the model on a smaller, task-specific dataset, we can tune its capabilities to align with the nuances and requirements of that domain.

Fine-tuning is analogous to transferring the wide-ranging knowledge of a highly educated generalist to craft an subject matter expert specialized in a certain field. In this guide, we’ll explore the whats, whys, and hows of fine-tuning LLMs.

Fine-tuning Large Language Models

What is Fine-Tuning?

At its core, fine-tuning involves taking a large pre-trained model and updating its parameters using a second training phase on a dataset tailored to your target task or domain. This allows the model to learn and internalize the nuances, patterns, and objectives specific to that narrower area.

While pre-training captures broad language understanding from a huge and diverse text corpus, fine-tuning specializes that general competency. It’s akin to taking a Renaissance man and molding them into an industry expert.

The pre-trained model’s weights, which encode its general knowledge, are used as the starting point or initialization for the fine-tuning process. The model is then trained further, but this time on examples directly relevant to the end application.

By exposing the model to this specialized data distribution and tuning the model parameters accordingly, we make the LLM more accurate and effective for the target use case, while still benefiting from the broad pre-trained capabilities as a foundation.

Why Fine-Tune LLMs?

There are several key reasons why you may want to fine-tune a large language model:

Domain Customization: Every field, from legal to medicine to software engineering, has its own nuanced language conventions, jargon, and contexts. Fine-tuning allows you to customize a general model to understand and produce text tailored to the specific domain.

Task Specialization: LLMs can be fine-tuned for various natural language processing tasks like text summarization, machine translation, question answering and so on. This specialization boosts performance on the target task.

Data Compliance: Highly regulated industries like healthcare and finance have strict data privacy requirements. Fine-tuning allows training LLMs on proprietary organizational data while protecting sensitive information.

Limited Labeled Data: Obtaining large labeled datasets for training models from scratch can be challenging. Fine-tuning allows achieving strong task performance from limited supervised examples by leveraging the pre-trained model’s capabilities.

Model Updating: As new data becomes available over time in a domain, you can fine-tune models further to incorporate the latest knowledge and capabilities.

Mitigating Biases: LLMs can pick up societal biases from broad pre-training data. Fine-tuning on curated datasets can help reduce and correct these undesirable biases.

In essence, fine-tuning bridges the gap between a general, broad model and the focused requirements of a specialized application. It enhances the accuracy, safety, and relevance of model outputs for targeted use cases.

Fine-tuning Large Language Models

Fine-Tuning Approaches

There are two primary strategies when it comes to fine-tuning large language models:

1) Full Model Fine-tuning

In the full fine-tuning approach, all the parameters (weights and biases) of the pre-trained model are updated during the second training phase. The model is exposed to the task-specific labeled dataset, and the standard training process optimizes the entire model for that data distribution.

This allows the model to make more comprehensive adjustments and adapt holistically to the target task or domain. However, full fine-tuning has some downsides:

It requires significant computational resources and time to train, similar to the pre-training phase.

The storage requirements are high, as you need to maintain a separate fine-tuned copy of the model for each task.

There is a risk of “catastrophic forgetting”, where fine-tuning causes the model to lose some general capabilities learned during pre-training.

Despite these limitations, full fine-tuning remains a powerful and widely used technique when resources permit and the target task diverges significantly from general language.

2) Efficient Fine-Tuning Methods

To overcome the computational challenges of full fine-tuning, researchers have developed efficient strategies that only update a small subset of the model’s parameters during fine-tuning. These parametrically efficient techniques strike a balance between specialization and reducing resource requirements.

Some popular efficient fine-tuning methods include:

Prefix-Tuning: Here, a small number of task-specific vectors or “prefixes” are introduced and trained to condition the pre-trained model’s attention for the target task. Only these prefixes are updated during fine-tuning.

LoRA (Low-Rank Adaptation): LoRA injects trainable low-rank matrices into each layer of the pre-trained model during fine-tuning. These small rank adjustments help specialize the model with far fewer trainable parameters than full fine-tuning.

Sure, I can provide a detailed explanation of LoRA (Low-Rank Adaptation) along with the mathematical formulation and code examples. LoRA is a popular parameter-efficient fine-tuning (PEFT) technique that has gained significant traction in the field of large language model (LLM) adaptation.

What is LoRA?

LoRA is a fine-tuning method that introduces a small number of trainable parameters to the pre-trained LLM, allowing for efficient adaptation to downstream tasks while preserving the majority of the original model’s knowledge. Instead of fine-tuning all the parameters of the LLM, LoRA injects task-specific low-rank matrices into the model’s layers, enabling significant computational and memory savings during the fine-tuning process.

Mathematical Formulation

LoRA (Low-Rank Adaptation) is a fine-tuning method for large language models (LLMs) that introduces a low-rank update to the weight matrices. For a weight matrix 0∈W0​∈Rd×k, LoRA adds a low-rank matrix BA, with A∈Rr×k and B∈Rd×r, where r is the rank. This approach significantly reduces the number of trainable parameters, enabling efficient adaptation to downstream tasks with minimal computational resources. The updated weight matrix is given by W=W0​+B⋅A.

This low-rank update can be interpreted as modifying the original weight matrix $W_0$ by adding a low-rank matrix $BA$. The key advantage of this formulation is that instead of updating all $d times k$ parameters in $W_0$, LoRA only needs to optimize $r times (d + k)$ parameters in $A$ and $B$, significantly reducing the number of trainable parameters.

Here’s an example in Python using the peft library to apply LoRA to a pre-trained LLM for text classification:

In this example, we load a pre-trained BERT model for sequence classification and define a LoRA configuration. The r parameter specifies the rank of the low-rank update, and lora_alpha is a scaling factor for the update. The target_modules parameter indicates which layers of the model should receive the low-rank updates. After creating the LoRA-enabled model, we can proceed with the fine-tuning process using the standard training procedure.

Adapter Layers: Similar to LoRA, but instead of low-rank updates, thin “adapter” layers are inserted within each transformer block of the pre-trained model. Only the parameters of these few new compact layers are trained.

Prompt Tuning: This approach keeps the pre-trained model frozen completely. Instead, trainable “prompt” embeddings are introduced as input to activate the model’s pre-trained knowledge for the target task.

These efficient methods can provide up to 100x compute reductions compared to full fine-tuning, while still achieving competitive performance on many tasks. They also reduce storage needs by avoiding full model duplication.

However, their performance may lag behind full fine-tuning for tasks that are vastly different from general language or require more holistic specialization.

The Fine-Tuning Process

Regardless of the fine-tuning strategy, the overall process for specializing an LLM follows a general framework:

Dataset Preparation: You’ll need to obtain or create a labeled dataset that maps inputs (prompts) to desired outputs for your target task. For text generation tasks like summarization, this would be input text to summarized output pairs.

Dataset Splitting: Following best practices, split your labeled dataset into train, validation, and test sets. This separates data for model training, hyperparameter tuning, and final evaluation.

Hyperparameter Tuning: Parameters like learning rate, batch size, and training schedule need to be tuned for the most effective fine-tuning on your data. This usually involves a small validation set.

Model Training: Using the tuned hyperparameters, run the fine-tuning optimization process on the full training set until the model’s performance on the validation set stops improving (early stopping).

Evaluation: Assess the fine-tuned model’s performance on the held-out test set, ideally comprising real-world examples for the target use case, to estimate real-world efficacy.

Deployment and Monitoring: Once satisfactory, the fine-tuned model can be deployed for inference on new inputs. It’s crucial to monitor its performance and accuracy over time for concept drift.

While this outlines the overall process, many nuances can impact fine-tuning success for a particular LLM or task. Strategies like curriculum learning, multi-task fine-tuning, and few-shot prompting can further boost performance.

Additionally, efficient fine-tuning methods involve extra considerations. For example, LoRA requires techniques like conditioning the pre-trained model outputs through a combining layer. Prompt tuning needs carefully designed prompts to activate the right behaviors.

Advanced Fine-Tuning: Incorporating Human Feedback

While standard supervised fine-tuning using labeled datasets is effective, an exciting frontier is training LLMs directly using human preferences and feedback. This human-in-the-loop approach leverages techniques from reinforcement learning:

PPO (Proximal Policy Optimization): Here, the LLM is treated as a reinforcement learning agent, with its outputs being “actions”. A reward model is trained to predict human ratings or quality scores for these outputs. PPO then optimizes the LLM to generate outputs maximizing the reward model’s scores.

RLHF (Reinforcement Learning from Human Feedback): This extends PPO by directly incorporating human feedback into the learning process. Instead of a fixed reward model, the rewards come from iterative human evaluations on the LLM’s outputs during fine-tuning.

While computationally intensive, these methods allow molding LLM behavior more precisely based on desired characteristics evaluated by humans, beyond what can be captured in a static dataset.

Companies like Anthropic used RLHF to imbue their language models like Claude with improved truthfulness, ethics, and safety awareness beyond just task competence.

Potential Risks and Limitations

While immensely powerful, fine-tuning LLMs is not without risks that must be carefully managed:

Bias Amplification: If the fine-tuning data contains societal biases around gender, race, age, or other attributes, the model can amplify these undesirable biases. Curating representative and de-biased datasets is crucial.

Factual Drift: Even after fine-tuning on high-quality data, language models can “hallucinate” incorrect facts or outputs inconsistent with the training examples over longer conversations or prompts. Fact retrieval methods may be needed.

Scalability Challenges: Full fine-tuning of huge models like GPT-3 requires immense compute resources that may be infeasible for many organizations. Efficient fine-tuning partially mitigates this but has trade-offs.

Catastrophic Forgetting: During full fine-tuning, models can experience catastrophic forgetting, where they lose some general capabilities learned during pre-training. Multi-task learning may be needed.

IP and Privacy Risks: Proprietary data used for fine-tuning can leak into publicly released language model outputs, posing risks. Differential privacy and information hazard mitigation techniques are active areas of research.

Overall, while exceptionally useful, fine-tuning is a nuanced process requiring care around data quality, identity considerations, mitigating risks, and balancing performance-efficiency trade-offs based on use case requirements.

The Future: Language Model Customization At Scale

Looking ahead, advancements in fine-tuning and model adaptation techniques will be crucial for unlocking the full potential of large language models across diverse applications and domains.

More efficient methods enabling fine-tuning even larger models like PaLM with constrained resources could democratize access. Automating dataset creation pipelines and prompt engineering could streamline specialization.

Self-supervised techniques to fine-tune from raw data without labels may open up new frontiers. And compositional approaches to combine fine-tuned sub-models trained on different tasks or data could allow constructing highly tailored models on-demand.

Ultimately, as LLMs become more ubiquitous, the ability to customize and specialize them seamlessly for every conceivable use case will be critical. Fine-tuning and related model adaptation strategies are pivotal steps in realizing the vision of large language models as flexible, safe, and powerful AI assistants augmenting human capabilities across every domain and endeavor.
