Top 19 Medical Datasets to Supercharge Your Machine Learning Models

[deepdreamnights]

Hey, you know how I said there was nothing ethical about Adobe's approach to AI? Well whaddya know?

Adobe wants your team lead to contact their customer service to not have your private documents scraped!

This isn't the first of Adobe's always-online subscription-based products (which should not have been allowed in the first place) to have sneaky little scraping permissions auto-set to on and hidden away, but this is the first one (I'm aware of) where you have to contact customer service to turn it off for a whole team.

Now, I'm on record for saying I see scraping as fair use, and it is. But there's an aspect of that that is very essential to it being fair use: The material must be A) public facing and B) fixed published work.

All public facing published work is subject to transformative work and academic study, the use of mechanical apparatus to improve/accelerate that process does not change that principle. Its the difference between looking through someone's public instagram posts and reading through their drafts folder and DMs.

But that's not the kind of work that Adobe's interested in. See, they already have access to that work just like everyone else. But the in-progress work that Creative Cloud gives them access to, and the private work that's never published that's stored there isn't in LIAON. They want that advantage.

And that's valuable data. For an example: having a ton of snapshots of images in the process of being completed would be very handy for making an AI that takes incomplete work/sketches and 'finishes' it. That's on top of just being general dataset grist.

But that work is, definitionally, not published. There's no avenue to a fair use argument for scraping it, so they have to ask. And because they know it will be an unpopular ask, they make it a quiet op-out.

This was sinister enough when it was Photoshop, but PDF is mainly used for official documents and forms. That's tax documents, medical records, college applications, insurance documents, business records, legal documents. And because this is a server-side scrape, even if you opt-out, you have no guarantee that anyone you're sending those documents to has done so.

So, in case you weren't keeping score, corps like Adobe, Disney, Universal, Nintendo, etc all have the resources to make generative AI systems entirely with work they 'own' or can otherwise claim rights to, and no copyright argument can stop them because they own the copyrights.

They just don't want you to have access to it as a small creator to compete with them, and if they can expand copyright to cover styles and destroy fanworks they will. Here's a pic Adobe trying to do just that:

If you want to know more about fair use and why it applies in this circumstance, I recommend the Electronic Frontier Foundation over the Copyright Alliance.

whenever tumblr has a viral post about a "good" project or idea related to ai I just assume it's not going to work.

Yeah, mostly the ones I've seen have to do with medical stuff, and generally medical domains make it very hard to get ML to work. There's just so many barriers. You have HIPAA making it hard to get large datasets. For labelled datasets you also need to pay a doctor to label images, which is expensive because doctors are expensive. And unlike other domains, where it's perfectly okay to have a "good enough" answer, with medical stuff generally it has to be really accurate. So all these papers are trying to get 95% accuracy+ generalization on like 500 samples, when realistically they need 100x as much, minimum. So to be honest, I find these diagnostic applications way more morally suspect than any image gen network. Maybe in the future if they pass legislation to allow ML training on anonymized medical scans, it'll get a lot better, but until then I don't expect much.

The few tumblr-approved applications outside of medical stuff I can think of are a pretty bad idea as well but for different reasons. Mostly because they expect it to actually be accurate

[atalienart]

Most importantly regarding AI, even if we ignored the entire discussion around "what is art? who can make it? what makes it valid?", the fact of the matter is that generative AI programs are inherently based on theft

Someone, some human(s), made the conscious decision to scrape the entire internet for literal billions of artworks, photos, videos, stories, blogs, social media posts, articles, copyrighted works, personal works, private works, private medical images. They took all of this data, crammed it all into a dataset for their generative programs to reference, and sold the idea of "look what a computer can 'create' from 'nothing' "

These programs do nothing on their own. They do not create spontaneously. They do not experiment or discover or express themselves. This is why they need data, a LOT of data, because they can only operate with designated user input, they can only regurgitate what has come before, they can only reference and repurpose what has come before. They steal from all of humanity, without due, without credit, without compensation or any sense of ethics, and the people vehemently selling the idea of AI are doing precisely that: selling it. They're exploiting the hard work, the identities, the privacy of billions of people for the sole purpose of making a quick, easy buck

In any sane world, the argument would end then and there, but unfortunately, we live in a world where are many of our laws are from the stone age (with people actively seeking to keep them there for fear of losing their power/influence). The creators of these AI programs are well-aware of these legal shortcomings, they have openly stated as such on numerous occasions, and are explicitly proud to be operating in this "legal grey area" because they know it means there are ill-gotten profits to be made

Regardless of whether or not a computer can genuinely make "art" or whether some person mashing words into a search bar is genuine "art", the fact of the matter is that it is objectively unethical in its current form. But, even that's an uphill battle to preach because too many people couldn't give a rats ass about ethics unless it personally affects them, and that's why we're in this position to begin with

I completely agree. It's entirely build on theft and it shouldn't exist. But as long as those who steal think they won't face any consequences and it brings them profit they won't stop. It's terrifying how so many people don't care about anything these days. It's just so frustrating to listen to all the excuses.

Virtual Pathologist

Image identification by machine learning models is a major application of artificial intelligence (AI). And, with ever-improving capabilities, the use of these models for medical diagnostics and research is becoming more commonplace. Doctors analysing X-rays and mammograms, for instance, are already being assisted by AI technology, and models trained to identify signs of disease in tissue sections are also being developed to help histopathologists. The models are trained with microscope images annotated by humans – the image, for example, shows a section of rat testis with signs of tubule atrophy (pale blue shapes) with other coloured shapes indicating normal tubules and structures. Once trained, the models are tasked with categorising unannotated datasets. The latest iteration of this technology was able to identify disease in testis, ovary, prostate and kidney samples with exceptional speed and high accuracy – in some cases finding signs of disease that even trained human pathologists had missed.

okay so like disregarding the horrid ethics of ai scraping without consent and compensation and the huge impact ai has on the environment, focusing solely on the claim companies love to make, that ai is a tool for artists, IF ai had stayed looking like shit, if the early days of dall e mini had been the extent of it's power, I could see it being a tool.

If it had stayed like this. Where everything is melting and hard to decipher, it could have been a tool specifically for practice. Because that's what it was when it first came out. Artists, before learning about the ethics of ai, saw these images and thought "wouldn't that be a fun exercise in interpretation?" and made redraws of these horrible awful images. It was a good exercise in creativity, it was fun to take these melting monstrosities and make them into something tangible. But then ai kept getting better at replicating actual images and now if you want a picture of an anime girl you can get one in just a few seconds and it looks like this

and that SUCKS. I can pick out the artists these images are pulling from, they have names and years of hard work under their belt and... what is there to do with these images really? This isn't a tool, there is no work to be done with them, they are, for all intents and purposes, the same as a finished illustration. The most an artist would do to these is make some small touch ups to make the blunders of ai like hair or clothing details not quite making sense, a little bit less noticeable. At that point it is not a tool. It does not aide the creative process, it takes it from the hands of the artist.

When ai gen images were first gaining traction and it still looked like shit. I did a few of these interpretation exercises and they were genuinely fun. The ai images were made by feeding Looking Glass AI some images of vocal synth character portraits and seeing what it spat out. And it spat out a lot of shit, girls with 8 arms and 4 legs and no head and hair for eyes and whatnot. So it was FUN and A TOOL because it looked so bad. Do I think the designs I interpreted from these are good? No not really. I think they could be if I did a few more passes to flesh them out, they aren't really something I'd usually design so it could be fun to keep letting them evolve, but as it stands they definitely need work.

But at the end of the day, saying all this, the fact of the matter is that ai image generation, in it's current state, regardless of what it looks like or how artists can or can't use it, doesn't matter. Because ai image generation is unethical. The scraping is unethical, the things that these datasets contain should be considered a violation of privacy considering some of them include pictures from MEDICAL DATA. And the environmental impact is absolutely abhorrent. The planet is already dying, do we need to speed it up for anime girl tiddies at the press of a button?

So if you're an artist looking to do an exercise like this where you look at something unintelligible and make sense of it with your pencil, what can you do? Well there's a few options really.

Having poor eyesight helps if you want to observe things in real life. take your glasses off and look around.

Look at the patterns in the paint on your ceiling or the stains on the floor or the marble texture of your counter top or the wood grain of a table or whatever else is around you.

Take poor quality screenshots of things you see online, you can even make the image quality worse digitally.

random paint or marker splotch doodle page. Draw over the shapes that random paint or marker marks make on a page.

take pictures of things from weird angles. distort them even more digitally if you want.

make collages in a photo app. I used to use pixlr in high school to make weird little pictures and while I never drew from them, they certainly changed the original images

I still think that if they ai looks bad enough that this kind of exercise can be fun and helpful if you're in a bit of an art block, and I do truly believe you can take inspiration from anything. I may take ai generated images that already exist on the internet, reference a few of them at once, and try to make something good out of them. But the way that ai exists right now, it just simply isn't the tool the companies are trying to sell you, and I most certainly won't be generating any new ai images any time soon.

[bitstitchbitch]

had to do a presentation on an ai application for my final project (idk why? It wasn’t an ai class). Made it bearable by focusing on medical imaging which does actually have potential benefits and is done with closed datasets, so not copyrighted data (though there are still privacy concerns as with any medical research) and I even managed to find a good fibromyalgia study to squeeze in there and that gave me a few opportunities to talk about the value of self-reported pain levels and I even got to explain fibromyalgia to someone!

Had to listen to other people talk about generative ai but all in all it wasn’t too awful

Still wish that professor had just let us do a computational em project (the topic of the class) instead of making us do an ai project because then I could have used my research topic that I’m already working, but that would have been logical

Radiology and AI expert Nina Kottler shares insights on how artificial intelligence is reshaping diagnostic imaging, clinical workflows, and radiologist roles. This episode of Bytes of Innovation dives into real-world impacts, emerging trends, and what's ahead for the field.

[hardwiredweird]

Genuine question: how does AI destroy the environment?

I'm totally with you on not using AI and that it harms artists but I've not heard the environment angle before.

I think a lot of people aren't aware of that because they don't think about how AI works.

While there are builds that can run on a local machine and even on phones, the way most people use generative machine learning systems like SD and ChatGPT is through a client (often a web client) where the actual processing takes place on remote servers. Those servers need power and cooling.

The processing power needed to generate millions and billions of images and text replies a day is immense, which means the power draw is horrendous. And all those servers need to be cooled. Often with water.

I think you see where there might be a severe environmental impact just from these factors alone. And for what?

Is "haha, funny image of my blorbo" really worth all that?

And then we're not even touching on the whole metric shitton of other ethical issues like the racism, sexism, ableism and mysoginy presented in the output or the medical data that's been scraped and put into the datasets or the fact that people are producing p*rn of real people and children or the potential legal ramifications of not being able to use photo evidence in legal procedings anymore or....

You know.

AI just all-round bad.

But there's still people justifying the use of it because "I'm just doing it for fun."

Despite uncovering widespread AI errors in healthcare, Ziad remained optimistic about how algorithms might help to care better for all patients. He felt they could be particularly useful in improving diagnostics that doctors tended to get wrong, but also in improving our current medical knowledge by discovering new patterns in medical data. Most modern healthcare AI is trained on doctors’ diagnoses, which Ziad felt wasn’t enough. ‘If we want AI algorithms to teach us new things,’ he said, ‘that means we can’t train them to learn just from doctors, because then it sets a very low ceiling – they can only teach us what we already know, possibly more cheaply and more efficiently.’ Rather than use AI as an alternative to human doctors – who weren’t as scarce as in rural India – he wanted to use the technology to augment what the best doctors could do.

[….]

To solve the mystery, Ziad had to return to first principles. He wanted to build a software that could predict a patient’s pain levels based on their X-ray scans. But rather than training the machine-learning algorithms to learn from doctors with their own intrinsic biases and blind spots, he trained them on patients’ self-reports. To do this, he acquired a training dataset from the US National Institutes of Health, a set of knee X-rays annotated with patients’ own descriptions of their pain levels, rather than simply a radiologist’s classification. The arthritis pain model he built found correlations between X-ray images and pain descriptions. He then used it to predict how severe a new patient’s knee pain was, from their X-ray. His goal wasn’t to build a commercial app, but to carry out a scientific experiment.

It turned out that the algorithms trained on patients’ own reported pain did a far better job than a human radiologist in predicting which knees were more painful.

The most striking outcome was that Ziad’s pain model outperformed human radiologists at predicting pain in African American patients. ‘The algorithms were seeing signals in the knee X-ray that the radiologist was missing, and those signals were disproportionately present in black patients and not white patients,’ he said. The research was published in 2021, and concluded: ‘Because algorithmic severity measures better capture underserved patients’ pain, and severity measures influence treatment decisions, algorithmic predictions could potentially redress disparities in access to treatments like arthroplasty.’

Meanwhile, Ziad plans to dig deeper to decode what those signals are. He is using machine-learning techniques to investigate what is causing excess pain using MRIs and samples of cartilage or bone in the lab. If he finds explanations, AI may have helped to discover something new about human physiology and neuroscience that would have otherwise been ignored.

For organizations and funding bodies These insights are essential to allocate resources as well as strategic plans. If they can understand where research is heading, they are able to help support research projects that are in line with future requirements, ultimately leading to improvements that benefit the entire society.

Ethical Considerations and Challenges

While the advantages of AI in speeding up research in photonics are evident however, ethical considerations need to be taken into consideration. Questions like privacy of data and bias in algorithmic computation, as well as the possibility of misuse by AI technology warrant careful consideration. Institutions and researchers must adopt responsible AI practices to ensure that the applications they use enhance human decision-making and not substitute it.

In addition, the incorporation in the use of AI into academic studies calls for the level of digital literacy which not every researcher are able to attain. Therefore, investing in education and education about AI methods and tools is vital to reap the maximum potential advantages.

Mastering Neural Networks: A Deep Dive into Combining Technologies

How Can Two Trained Neural Networks Be Combined?

Introduction

In the ever-evolving world of artificial intelligence (AI), neural networks have emerged as a cornerstone technology, driving advancements across various fields. But have you ever wondered how combining two trained neural networks can enhance their performance and capabilities? Let’s dive deep into the fascinating world of neural networks and explore how combining them can open new horizons in AI.

Basics of Neural Networks

What is a Neural Network?

Neural networks, inspired by the human brain, consist of interconnected nodes or "neurons" that work together to process and analyze data. These networks can identify patterns, recognize images, understand speech, and even generate human-like text. Think of them as a complex web of connections where each neuron contributes to the overall decision-making process.

How Neural Networks Work

Neural networks function by receiving inputs, processing them through hidden layers, and producing outputs. They learn from data by adjusting the weights of connections between neurons, thus improving their ability to predict or classify new data. Imagine a neural network as a black box that continuously refines its understanding based on the information it processes.

Types of Neural Networks

From simple feedforward networks to complex convolutional and recurrent networks, neural networks come in various forms, each designed for specific tasks. Feedforward networks are great for straightforward tasks, while convolutional neural networks (CNNs) excel in image recognition, and recurrent neural networks (RNNs) are ideal for sequential data like text or speech.

Why Combine Neural Networks?

Advantages of Combining Neural Networks

Combining neural networks can significantly enhance their performance, accuracy, and generalization capabilities. By leveraging the strengths of different networks, we can create a more robust and versatile model.

Methods of Combining Neural Networks

Ensemble Learning

Ensemble learning involves training multiple neural networks and combining their predictions to improve accuracy. This approach reduces the risk of overfitting and enhances the model's generalization capabilities.

Bagging

Bagging, or Bootstrap Aggregating, trains multiple versions of a model on different subsets of the data and combines their predictions. This method is simple yet effective in reducing variance and improving model stability.

Boosting

Boosting focuses on training sequential models, where each model attempts to correct the errors of its predecessor. This iterative process leads to a powerful combined model that performs well even on difficult tasks.

Stacking

Stacking involves training multiple models and using a "meta-learner" to combine their outputs. This technique leverages the strengths of different models, resulting in superior overall performance.

Transfer Learning

Transfer learning is a method where a pre-trained neural network is fine-tuned on a new task. This approach is particularly useful when data is scarce, allowing us to leverage the knowledge acquired from previous tasks.

Concept of Transfer Learning

In transfer learning, a model trained on a large dataset is adapted to a smaller, related task. For instance, a model trained on millions of images can be fine-tuned to recognize specific objects in a new dataset.

How to Implement Transfer Learning

To implement transfer learning, we start with a pretrained model, freeze some layers to retain their knowledge, and fine-tune the remaining layers on the new task. This method saves time and computational resources while achieving impressive results.

Advantages of Transfer Learning

Transfer learning enables quicker training times and improved performance, especially when dealing with limited data. It’s like standing on the shoulders of giants, leveraging the vast knowledge accumulated from previous tasks.
