the generative noise reduction artifact experiments that people call "AI Art" were not initially a collage machine, but grew closer to one over time as demands for accuracy and beautiful convincing results without any extra interactions were heeded. overfitting has gotten easier to do accidentally as models have focused more on using smaller datasets efficiently after running into the ceiling of "oops, that's all the data on earth." of course it still can't point you towards the parts of its training data that it "used" because all of it is already in the bread, its just a shit image search now.

Any more Headcannons for Ultimus Richtofen and his s/o? Bonus points if it's for him helping them with life with their AuHd

💫 Welcome, welcome!! I do in fact have some HC’s for this, so let’s do it!! ✨

💫 Richtofen with an AuDHD S/O HC’s!! ✨

✨ Your first mistake is thinking that he helps his s/o.(/j) Richtofen also has AuDHD and his aggressive hyperactivity would either encourage his s/o to be the same way or overstimulate them severely.

✨ If his s/o was medicated for their ADHD, he would happily support them by making sure they take their medicine, but he wouldn’t exactly be too fussed if they chose not to go down the medication route.

✨ Richtofen could listen to his s/o talk for hours, which he probably has done before without saying a word. When his s/o loses their train of thought, he’ll help them find their place again— If he’s able to remember.

✨ If not, Richtofen will ask a question he thinks is related just so he can listen to his s/o talk more.

✨ Richtofen will bug his s/o. Tapping them, poking them, waking them up just as they nod off. It’s all on the table. Richtofen knows it’s overstimulating sometimes and that’s why he does it, he’s a menace and that’s how he shows his love.

✨ He will make a point of doing his best to remember his s/o’s special interests and will ask questions about them if he has any.

✨ If his s/o needs any accommodations like noise reduction or fidget toys, he is more than happy to provide them!! He likely has some fidget toys of his own that he lends them.

✨ Richtofen sticks to a routine, and if his s/o has one, he helps them stick to theirs as well, it’s a way of bonding that isn’t just irritating them.

✨ Given his time served in the war, Richtofen knows some breathing exercises and will employ them to help calm his s/o if everything is too much.

✨ Rather than parallel play, Richtofen will prefer to just be in the presence of his s/o, even if he’s not doing anything while they are. If he’s working, he also likes his s/o to just be near by.

✨ when noticing his s/o is masking around him- And he does notice, he will call it out and laugh in a teasing way. Pointing it out will make his s/o drop their mask and laugh with him, meaning they’re comfortable around him.

✨ If his s/o and him have any shared interests, their down time is filled with interacting with those interests for as long as they’re allowed. He loves enthusing with them about shared passions.

✨ Richtofen is prone to getting defensive if someone is judging his s/o for their AUDHD traits. He will speak up for them and defend them with all he has until his s/o has to drag him away from the confrontation lest it turn into a fight.

💫 Thank you so much for your ask and I hope these were satisfactory!! ✨

✨ NEXT! > ⭐️

"I think we have to say first and foremost that there is zero evidence whatsoever that anything to do with the FAA's efforts to hire people of diverse backgrounds, people with disabilities, had anything to do with this tragedy.

. . .

First of all, at that press conference, president Trump read out a sentence from the Biden-era FAA website about the FAA's desire to hire people with so-called targeted disabilities. Those are significant disabilities like psychiatric and intellectual issues, paralysis, missing extremities, and so on. What he did not mention was that that exact language was on the FAA website under president Trump the entirety of his own administration. We grabbed a screenshot from December 2020 late in his first term, so this was not something Biden invented. In fact, it's been on that website at least since 2013."

. . .

"No. 2, this was not just language on a Trump-era website," Dale added. "In fact, in 2019, under president Trump, the FAA launched a pilot program specifically to hire people with these so-called targeted disabilities – intellectual, psychiatric, etc, in air traffic control roles, so they emphasized at the time, these people would have to meet all criteria in terms of medical criteria, qualifications, security criteria. But regardless, this was not something the Biden administration invented, as he suggested."

For years, the Metropolitan Washington Airports Authority warned Congress that the region’s airports were at capacity, DeFazio said in an interview with POLITICO Magazine. But their pleas for restraint fell short among lawmakers, who voted to add more flights to an airport already struggling with its heavy load and a shortage of air traffic controllers caused by previous government shutdowns and pandemic-era hits to its workforce.

“Every senator in particular wants a nonstop flight to and from wherever they live,” said DeFazio, an Oregon Democrat.

. . .

This is an incredibly congested airspace. First off, if the military wants to run training missions, they could run them between 10 p.m. and 6 a.m., when Washington National has noise reductions in place and traffic is dramatically reduced. I don’t see any reason to be running training missions during peak hours.

. . .

Secondly, it’s unbelievable that the president of the United States and three of his minions — Secretary [Sean] Duffy, Secretary [Pete] Hegseth, and Vice President [JD] Vance — immediately blamed DEI. I mean, let’s be real here. All air traffic controllers go through the same training. They have to pass the same unbelievably rigorous test. It’s a very, very stressful job.

Disability employment law, she says, requires "that the person with a disability must be able to perform the essential functions of the job."

. . .

"To scapegoat people with disabilities for this tragedy just seems inconsistent with the facts," Katy Neas, chief executive officer of The Arc of the United States, which advocates for people with intellectual and developmental disabilities, told NPR.

"It's very sad that this stigma against people with disabilities continues to be used as a reason why qualified people can't be hired."

THE WOMAN WHO OUTSMARTED EDISON: Meet Mary Walton, the Forgotten Genius Who Cleaned Up America!

In the smoky, noisy chaos of 1800s New York City, when even Thomas Edison couldn't solve the pollution crisis, one determined woman rolled up her sleeves and changed everything. Mary Walton didn't just complain about the problems - she fixed them!

BASEMENT BREAKTHROUGH: From Problem to Patent

While cities choked on black locomotive smoke and soot covered every building, Mary Walton got to work in her basement. She studied how smoke moved, built prototypes, and invented a revolutionary system that forced train emissions through water tanks, trapping pollutants before they reached the air. Her 1879 patent transformed city life overnight!

NOISE NIGHTMARE SOLVED: When Edison Failed, Mary Succeeded

New York's elevated trains created unbearable noise that rattled buildings and kept residents awake. Thomas Edison tried to fix it and failed completely. But Mary Walton didn't give up! She discovered that wooden support boxes amplified the sound and created an ingenious dampening system that finally gave New Yorkers peace and quiet.

REVOLUTIONARY IMPACT: Double Innovation Champion

At a time when women rarely held patents, Mary Walton earned not one but TWO groundbreaking patents that solved major urban problems. Her smoke reduction system was adopted by railroads nationwide, while her noise dampening technology was purchased by New York's Metropolitan Railroad, making her financially successful too!

LASTING LEGACY: Environmental Pioneer Ahead of Her Time

Mary Walton was essentially the world's first environmental engineer! Her innovations didn't just clean the air and quiet the streets - they proved that ordinary people could solve extraordinary problems through observation, experimentation, and determination. Cities worldwide still benefit from the principles she pioneered over 140 years ago.

Next time you breathe clean city air or enjoy a quiet train ride, remember Mary Walton - the brilliant woman who showed that innovation knows no gender!

aww thats swell! hope you got to make many warm and kind memories with your boyfriend!

ive been okay recently, just moseying along, trying to find work (i trained as a peer support worker last year and finished up my practicum early this year). i had a question regarding voice acting; im in no way a va but i thought it'd be fun to apply for the posting i sent your way. itd be cool to pick up a high school hobby (of general drama/acting), and i can tell myself i tried!

only issue is i have no idea what program to use to record. my friend whos more into audio tech and programming in general looked up reaper and ive been wrestling with it with off and on again success haha. friend is really knowledgeable about the technical side of audio and music, but as someone with literally a blank slate experience, im finding myself overwhelmed by the technical aspects. would you happen to have any insight on where i can look for tutorials/advice/beginner voice recording stuff?

hehe thank you!! it was a great trip and im really happy i got a chance to go :> (i just hope i can come visit again soon alsjdfh)

But i'm glad to hear you've been okay and hoping that the peer support work goes well!!

oh yeah va has been a very fun hobby to do (i've been doing va as a hobby since high school myself haha but was Very shy about it because 'serious student persona'), so it's definitely worth giving a shot at least once!

i know reaper has a biiiig learning curve and i know eventually i also want to learn how to make use of that since it sounds like it has way more functions, but i personally use audacity because it's a pretty simple program that's overall pretty straightforward to use! there's a lot of functions that can be overwhelming but my main go tos is the noise reduction (to clean out the background noise by sampling 2 seconds of silence in your recording before clearing from the rest), compression (which stabilizes the volume of all the audio), and then normalize (to help with volume control).

i'm also not super well versed on the technical side of audio recording, but at the very least with voice acting and all, it really is just a hobby that you just have to do. so auditioning for gb patch's casting call is one way of doing that! and if not that, then just record yourself reading as characters you like and whatnot. like ik pretty early on with vaing i was just doing random voices as characters while i wasplaying danganronpa. so things like that :'D

hopefully that kinda answers some questions for voice recording but :'>

oh also warm up your voice before you do it. don't strain your voice and figure out what's the most comfortable for you when it comes to voicing.

i acquired noise reduction headphones over the winter break and this has been life changing. earplugs cannot even compare. the luxury of listening to very quiet classical music on a train or any other loud public setting... or just wearing them with nothing playing when walking in the street... just me and the silence

[anarkittyuwuuniverse]

I think there's a certain type of person - I guess the ones who get all their information about "neurodivergence" through social media - who just kind of need to be told: Hey, the reason why people express doubt about you claiming to be autistic is not because autism has been "stereotyped" as this screaming non-verbal head-banging nursery rhyme and train obsessed young boy archetype (whom I'm sure you are probably very passionate about advocating for), it's because the diagnostic category of autism has widened and broadened so much in the latest years both within psychiatry but especially within pop psychology social media spaces that the image of autism you have been presented with is completely unrecognizable from the image of autism a lot of people have grown up with. This cannot be explained away with vague gestures towards "stereotyping" or "it's a spectrum", it's only a spectrum because some psychiatrists decided to pair a bunch of traits they saw occurring together under the same label but then sometimes they would occur with other traits and the chain just gets so long and the edges so far from each other, no single core to consistently unite all of it. And that's one thing but a lot of the things held up as "autism traits" on TikTok or Instagram infographics are just completely ordinary and trivial things. I've seen posts saying that being sensitive to conflict, scared of horror movies, having hobbies and interests, having strong moral beliefs, fidgeting (no reference to extent of fidgeting) and enjoying saying funny noises are all signs of autism and I just. A lot of the stuff I see is also just responding with stress to stressful situations, getting overwhelmed from socializing for a long time, struggling to balance home and work-life balance (this one was presented as a trait in autistic women hmm, I wonder why women specifically would struggle more to hold both a job and keep a household in order) and I think a problem is that a lot of people genuinely don't know that other people are also really fucking struggling because it's not visible most of the time, just as your suffering is not visible to others because you are "masking". I get that it feels good to get a label that kind of acknowledges and validates your suffering but there are other ways to do that, ways that don't make your suffering an essential part about who you are and encourages identity formation around it, it is also very likely that the people pushing for this broadening of the term are looking for customers to sell self-help to. It's a bit of a cliché to say that a lot of these problems are caused by capitalism but there is some truth to it, though it is reductive. A lot of people also just feel alienated because the way social dynamics are in many societies just are highly alienating, people interrogate and scrutinize each other's behavior all the time and everyone's hiding and performing so much and in a globalized ever accelerating neoliberal society, there are so many different kinds of constantly disrupting social spaces people find themselves in all the time, so many new forms of labor that require high degrees of emotional regulation and intuitiveness, and constant new norms being generated, no wonder more and more people feel like they "don't understand social norms". (This post is not an attack on any person who identifies as autistic or has low support needs though I am highly critical of the ontology of the diagnosis, it can be relevant to some people. You decide whether or not this post applies to you.)

[thevoiceofdog]

Reiterating Our Position on AI.

Given this platform's recent intent to sell user data to generative AI companies, we had to put a lot of consideration into deleting this blog.

We're not going to. Yet.

To be clear, it has been and will always remain the position of the Voice of Dog that nothing of what we feature on the show is AI-generated. Submitted stories must be in your own words, which absolutely rules out AI, and we reserve the right to deny or remove a story if we have reason to believe AI--or any other means of plagiarism--has been used to make it. All the stories are by real members of the furry community. Any images are by actual artists, even if only on a let-me-ask-if-my-boyfriend-will-draw-that basis, as is tradition. The closest an AI will ever get to anything you hear from us is the spell-check in someone's word processor or the noise-reduction filter in someone's audio editing software.

We have zero confidence that the opt-out in the blog settings will be respected, especially given reports that Tumblr's intended enforcement mechanism is the honor system. This will stop nothing.

But given the possibility that it is an attempt to assemble a "clean" training database, that companies will attempt to claim is fully consensual despite inevitably containing data from writers and artists who did not in any consent, we are making the following statement: We do not consent for any material to be used for the purposes of training generative AI. Not one word. Not one pixel. Not one second of audio.

One factor in this has been that we don't anticipate that anything they take from us--and we expect they will, again, we have zero confidence that the opt-out will be in any way respected either by Tumblr or the companies they sell user data to--will actually be useful. Our episodes are not embedded. What will they get? The "today's story is-" intros, some promotion of author's other works, and URLs to where episodes can be listened to. None of that data is useful.

Another factor is that, if they want to copy and plagiarize our work, they don't need Tumblr's help to do it. The only way to keep them from copying the stories we tell would be to not tell stories, which is not an option and will never be an option. This does not constitute consent! The act of plagiarism is and remains reprehensible, but it is not on us to prevent you from practicing it against us. The fact we cannot realistically stop a plagiarist makes them more culpable, not less.

It remains very possible that this decision will cause the collapse of the community here, such that there will be no benefit to remaining.

Until such a time, So long as any soul has a story to tell, So long is any listener waits at the fireside, We will be here.

Thank you for listening to the Voice of Dog.

Tamaki fights plans to build SDF training site in Okinawa

(This article was compiled from reports by Nen Satomi, Taro Ono and Satsuki Tanahashi.)

NAHA--Okinawa Governor Denny Tamaki called on Defense Minister Minoru Kihara to retract plans to build a Self-Defense Force training site in his prefecture as the central government moves to bolster defenses in the nation’s southwestern islands.

“We cannot agree with the project,” Tamaki told Kihara at the Okinawa prefectural government office here Feb. 17 during a meeting that lasted less than 30 minutes. “We want the government to take the plan back to the drawing board and review it.”

The Defense Buildup Program, one of the three national security documents the government adopted in 2022, calls for enhancing SDF capabilities in southwestern Japan, centered around Okinawa Prefecture, due to China’s growing presence in the East China Sea.

The document said the Ground SDF’s 15th Brigade, which is based in Naha and comprises around 2,000 members, will be reorganized into a division.

The GSDF plans to open a new training ground in Uruma, Okinawa Prefecture, to handle the range of exercises required for the expanded division.

“In the face of the most severe and complicated security environment Japan has faced after World War II, we can lose no time in drastically reinforcing our defense capabilities based on the three national security documents,” Kihara told Tamaki during the meeting.

The proposed training site lies next to a residential area.

Residents are concerned about noise issues and the potential for accidents. Neighborhood community associations had already called for scrapping the project.

The meeting with Kihara marked the first time for Tamaki to publicly express his opposition to the project.

“The government has been hastily pressing everything forward particularly after it published the three security documents,” Tamaki told reporters after the meeting. “Anxiety among many prefectural residents is only growing, not subsiding.”

Before his meeting with Tamaki, Kihara sat down for talks with the heads of 11 municipalities in Okinawa Prefecture that host U.S. military bases.

Uruma Mayor Masato Nakamura told Kihara, “We want the central government to take the voices of local residents seriously and give careful consideration to the issue.”

Tamaki and Kihara also remained far apart over the project to relocate the U.S. Marine Corp Air Station Futenma in Ginowan, Okinawa Prefecture, to Nago, also in the prefecture.

While Tamaki renewed his call for suspending reclamation work, Kihara stressed that the government would forge ahead with the divisive project.

The Defense Ministry started reclamation work in Oura Bay north of Henoko Point in Nago in January after land minister Tetsuo Saito approved design changes by proxy the previous month, overriding Tamaki’s refusal to sign off on the modifications.

During the meeting, Tamaki called for convening a session of the Futenma air station burden reduction promotion council, which would bring together Kihara, Tamaki, Chief Cabinet Secretary Yoshimasa Hayashi, Ginowan Mayor Masanori Matsugawa and others.

The meeting was last held five years ago.

But Kihara said working-level officials will discuss the issue at a working group under the council.

“We renewed our determination to produce solid results toward reducing Okinawa’s base burden and drastically reinforcing defense capabilities in the southwestern region,” Kihara told reporters after the meeting.

Kihara’s visit was his first to Okinawa’s main island since taking office in September, which is exceptionally overdue for a newly appointed defense minister.

He visited Miyakojima and Ishigakijima, two islands in Okinawa Prefecture, in September to inspect GSDF units deployed at camps that opened in 2019 and March 2023, respectively.

Kihara met with Tamaki, who has consistently called for easing the U.S. bases burden borne by his prefecture, for the first time at the Defense Ministry in Tokyo in January.

Quantum convolutional neural networks for feature processing

Quantum convolutional neural networks improve picture categorisation and feature processing.

Scientists have developed a novel quantum convolutional neural network (QCNN) technology that could improve picture categorisation efficiency and accuracy. Quantum physics is used to solve challenging pattern recognition issues that challenge conventional computer methods.

This study is led by Shaswata Mahernob Sarkar, Sheikh Iftekhar Ahmed, and colleagues from the University of Rochester and Bangladesh University of Engineering and Technology. Their research uses a parallel-mode QCNN and selective feature re-encoding to improve feature processing and classification accuracy.

Image Processing with Quantum Technology

Quantum CNN for image classification

Noisy Intermediate-Scale Quantum (NISQ) devices are advancing quantum machine learning. It has many uses, including image recognition. Despite their success, standard convolutional neural networks (CNNs) are computationally expensive and resource-intensive, especially for big and complicated datasets. This inherent limitation of standard CNNs has spurred research into Quantum Convolutional Neural Networks (QCNNs), which have superior representational capacity and computing efficiency. QCNNs use quantum notions like entanglement and superposition to improve image categorisation.

New Feature Extraction Methods

The researchers introduce two major breakthroughs in this groundbreaking study:

Selective Feature Re-Encoding Strategy: This novel method forces quantum circuits to prioritise an input image's most informative features. By selecting and encoding only the most important data, this method increase signal-to-noise ratio and reduce processing load. The quantum system uses this targeted strategy to explore Hilbert space, the complicated vector space that describes all quantum system states, to discover the optimal feature processing solutions.

A New Parallel QCNN Architecture: This complicated approach integrates PCA and autoencoder features into a single training scheme.

PCA, a popular dimensionality reduction method, identifies the most important variances in data.

In contrast, autoencoders are neural networks that train to efficiently extract important properties from compressed input data. By combining PCA and autoencoders in a quantum framework, the research team hopes to increase classification performance by creating a more precise and trustworthy feature representation.

Thorough Verification and Excellent Results

These methods were thoroughly tested using MNIST and Fashion-MNIST, two popular photo datasets. The number of qubits, the quantum equivalent of classical bits, and the quantum circuit depth affect the QCNN's performance. Investigations were crucial to showing this. The importance of optimisation and fine-tuning in QCNN design is highlighted.

The jointly optimised parallel QCNN architecture consistently outperformed both individual QCNN models and conventional ensemble approaches. Merging PCA and Autoencoders within the quantum framework gives the QCNN a more complete and trustworthy feature representation of input images, which improves performance.

Common quantum computing topics like orthogonal matrix decomposition and two-qubit gate circuit topologies underpin this study. Using strong quantum simulation and machine learning software tools and frameworks like TensorFlow Quantum and PennyLane helped with development and testing. This study's code and data are freely available in the quantum machine learning community to encourage repeatability and collaboration.

Introducing Future Quantum Developments

Over time, the study team hopes to increase the adoption of their QCNN design. They will test its applicability in more difficult picture classification tasks like object recognition and image segmentation. They may also consider employing more advanced quantum algorithms to boost performance. The development of hardware-efficient Quantum Convolutional Neural Networks (QCNNs) architectures for near-term quantum devices will also be prioritised, moving this technology towards real-world deployment.

To conclude, this pioneering study reveals how quantum convolutional neural networks may perform at the forefront of image classification tasks and how to build a trustworthy and effective system. The innovative parallel QCNN architecture and inventive feature encoding approaches have produced a system that outperforms conventional methods, paving the way for quantum machine learning advancements.

One of the best On3 scale model train dioramas with Shay, Climax and Heisler steam locomotives

Jul 6, 2025 There is a special type of steam locomotive, the so-called geared steam locomotive. The steam locomotive, as commonly employed, has its pistons directly attached to cranks on the driving wheels; thus, there is no gearing. A geared steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design. This gearing is part of the machinery within the locomotive and should not be confused with the pinion that propels a rack locomotive along the rack between the rails.

Well-known geared steam locomotives are the Shay locomotive, the Climax locomotive and the Heisler locomotive. The Shay locomotive features an offset boiler with a multiple-cylinder engine affixed to it on the opposite side, driving a longitudinal shaft geared to the axles via bevel gears. The Climax locomotive has two inclined cylinders driving a transverse crankshaft, geared to a longitudinal driveshaft placed centrally on the locomotive and driving the powered trucks via internal gearing. The Heisler locomotive has one cylinder each side of the boiler, affixed to a centrally located longitudinal driveshaft, again geared to the wheels.

René Paul, a railway enthusiast and model builder from the Netherlands, was so fascinated by these special steam locomotives that he constructed a wonderful model train diorama. The model railroad layout depicts a typical American railroad junction in a small town. The miniature world was constructed in On3 scale (1/48 scale) as a shunting layout for sorting and shunting goods wagons with the help of these impressive geared steam locomotives. The model railway layout is 2.85 meters long and 0.60 meters wide. All rail and turnouts are hand built. There are no kits. There are no prefabricated buildings. The attention to detail is sensational, for example, four nails are placed in each sleeper.

In the foreground is the continuous track from which a turnout branches off. This serves two warehouses with sidings on the left-hand side of the model train layout. Opposite, i.e. on the right-hand side of the model railroad layout, is an engine shed for the narrow-gauge locomotives with a workshop and with the necessary facilities for maintaining the rolling stock. The model train diorama was filmed at a large model railroad exhibition in Luxembourg. Because there were too many noises from visitors, Pilentum Television dubbed the video with authentic sounds.
