Why do I still have to work my boring job while AI gets to create art and look at boobs?

[-] SomeGuy69@lemmy.world 53 points 3 months ago

Because life is suffering and machines dream of electric sheeps.

Now make mammograms not $500 and not have a 6 month waiting time and make them available for women under 40. Then this'll be a useful breakthrough

[-] ConstantPain@lemmy.world 78 points 3 months ago

It's already this way in most of the world.

[-] ALoafOfBread@lemmy.ml 42 points 3 months ago* (last edited 3 months ago)

Oh for sure. I only meant in the US where MIT is located. But it's already a useful breakthrough for everyone in civilized countries

Better yet, give us something better to do about the cancer than slash, burn, poison. Something that's less traumatic on the rest of the person, especially in light of the possibility of false positives.

Unfortunately AI models like this one often never make it to the clinic. The model could be impressive enough to identify 100% of cases that will develop breast cancer. However if it has a false positive rate of say 5% it’s use may actually create more harm than it intends to prevent.

Another big thing to note, we recently had a different but VERY similar headline about finding typhoid early and was able to point it out more accurately than doctors could.

But when they examined the AI to see what it was doing, it turns out that it was weighing the specs of the machine being used to do the scan... An older machine means the area was likely poorer and therefore more likely to have typhoid. The AI wasn't pointing out if someone had Typhoid it was just telling you if they were in a rich area or not.

[-] KevonLooney@lemm.ee 22 points 3 months ago

That's actually really smart. But that info wasn't given to doctors examining the scan, so it's not a fair comparison. It's a valid diagnostic technique to focus on the particular problems in the local area.

That's why these systems should never be used as the sole decision makers, but instead work as a tool to help the professionals make better decisions.

Keep the human in the loop!

[-] CptOblivius@lemmy.world 16 points 3 months ago

Breast imaging already relys on a high false positive rate. False positives are way better than false negatives in this case.

The most beneficial application of AI like this is to reverse-engineer the neural network to figure out how the AI works. In this way we may discover a new technique or procedure, or we might find out the AI's methods are bullshit. Under no circumstance should we accept a "black box" explanation.

[-] CheesyFox@lemmy.sdf.org 29 points 3 months ago

good luck reverse-engineering millions if not billions of seemingly random floating point numbers. It's like visualizing a graph in your mind by reading an array of numbers, except in this case the graph has as many dimensions as the neural network has inputs, which is the number of pixels the input image has.

Under no circumstance should we accept a "black box" explanation.

Go learn at least basic principles of neural networks, because this your sentence alone makes me want to slap you.

[-] thecodeboss@lemmy.world 13 points 3 months ago

Don't worry, researchers will just get an AI to interpret all those floating point numbers and come up with a human-readable explanation! What could go wrong? /s

[-] petrol_sniff_king 12 points 3 months ago

Hey look, this took me like 5 minutes to find.

Censius guide to AI interpretability tools

Here's a good thing to wonder: if you don't know how you're black box model works, how do you know it isn't racist?

Here's what looks like a university paper on interpretability tools:

As a practical example, new regulations by the European Union proposed that individuals affected by algorithmic decisions have a right to an explanation. To allow this, algorithmic decisions must be explainable, contestable, and modifiable in the case that they are incorrect.

Oh yeah. I forgot about that. I hope your model is understandable enough that it doesn't get you in trouble with the EU.

Oh look, here you can actually see one particular interpretability tool being used to interpret one particular model. Funny that, people actually caring what their models are using to make decisions.

Look, maybe you were having a bad day, or maybe slapping people is literally your favorite thing to do, who am I to take away mankind's finer pleasures, but this attitude of yours is profoundly stupid. It's weak. You don't want to know? It doesn't make you curious? Why are you comfortable not knowing things? That's not how science is propelled forward.

iirc it recently turned out that the whole black box thing was actually a bullshit excuse to evade liability, at least for certain kinds of model.

IMO, the "black box" thing is basically ML developers hand waiving and saying "it's magic" because they know it will take way too long to explain all the underlying concepts in order to even start to explain how it works.

I have a very crude understanding of the technology. I'm not a developer, I work in IT support. I have several friends that I've spoken to about it, some of whom have made fairly rudimentary machine learning algorithms and neural nets. They understand it, and they've explained a few of the concepts to me, and I'd be lying if I said that none of it went over my head. I've done programming and development, I'm senior in my role, and I have a lifetime of technology experience and education... And it goes over my head. What hope does anyone else have? If you're not a developer or someone ML-focused, yeah, it's basically magic.

I won't try to explain. I couldn't possibly recall enough about what has been said to me, to correctly explain anything at this point.

[-] homura1650@lemm.ee 21 points 3 months ago

The AI developers understand how AI works, but that does not mean that they understand the thing that the AI is trained to detect.

For instance, the cutting edge in protein folding (at least as of a few years ago) is Google's AlphaFold. I'm sure the AI researchers behind AlphaFold understand AI and how it works. And I am sure that they have an above average understanding of molecular biology. However, they do not understand protein folding better than the physisits and chemists who have spent their lives studying the field. The core of their understanding is "the answer is somewhere in this dataset. All we need to do is figure out how to through ungoddly amounts of compute at it, and we can make predictions". Working out how to productivly throw that much compute power at a problem is not easy either, and that is what ML researchers understand and are experts in.

In the same way, the researchers here understand how to go from a large dataset of breast images to cancer predictions, but that does not mean they have any understanding of cancer. And certainly not a better understanding than the researchers who have spent their lives studying it.

An open problem in ML research is how to take the billions of parameters that define an ML model and extract useful information that can provide insights to help human experts understand the system (both in general, and in understanding the reasoning for a specific classification). Progress has been made here as well, but it is still a long way from being solved.

If it has just as low of a false negative rate as human-read mammograms, I see no issue. Feed it through the AI first before having a human check the positive results only. Save doctors' time when the scan is so clean that even the AI doesn't see anything fishy.

Alternatively, if it has a lower false positive rate, have doctors check the negative results only. If the AI sees something then it's DEFINITELY worth a biopsy. Then have a human doctor check the negative readings just to make sure they don't let anything that's worth looking into go unnoticed.

Either way, as long as it isn't worse than humans in both kinds of failures, it's useful at saving medical resources.

[-] match@pawb.social 21 points 3 months ago

an image recognition model like this is usually tuned specifically to have a very low false negative (well below human, often) in exchange for a high false positive rate (overly cautious about cancer)!

Ok, I'll concede. Finally a good use for AI. Fuck cancer.

[-] ilinamorato@lemmy.world 26 points 3 months ago

It's got a decent chunk of good uses. It's just that none of those are going to make anyone a huge ton of money, so they don't have a hype cycle attached. I can't wait until the grifters get out and the hype cycle falls away, so we can actually get back to using it for what it's good at and not shoving it indiscriminately into everything.

Honestly they should go back to calling useful applications ML (that is what it is) since AI is getting such a bad rap.

This is similar to wat I did for my masters, except it was lung cancer.

Stuff like this is actually relatively easy to do, but the regulations you need to conform to and the testing you have to do first are extremely stringent. We had something that worked for like 95% of cases within a couple months, but it wasn't until almost 2 years later they got to do their first actual trial.

[-] bluefishcanteen@sh.itjust.works 21 points 3 months ago

This is a great use of tech. With that said I find that the lines are blurred between "AI" and Machine Learning.

Real Question: Other than the specific tuning of the recognition model, how is this really different from something like Facebook automatically tagging images of you and your friends? Instead of saying "Here's a picture of Billy (maybe) " it's saying, "Here's a picture of some precancerous masses (maybe)".

That tech has been around for a while (at least 15 years). I remember Picasa doing something similar as a desktop program on Windows.

[-] AdrianTheFrog@lemmy.world 15 points 3 months ago

I've been looking at the paper, some things about it:

  • the paper and article are from 2021
  • the model needs to be able to use optional data from age, family history, etc, but not be reliant on it
  • it needs to combine information from multiple views
  • it predicts risk for each year in the next 5 years
  • it has to produce consistent results with different sensors and diverse patients
  • its not the first model to do this, and it is more accurate than previous methods

Serious question: is there a way to get access to medical imagery as a non-student? I would love to do some machine learning with it myself, as I see lot’s of potential in image analysis in general. 5 years ago I created a model that was able to spot certain types of ships based only on satellite imagery, which were not easily detectable by eye and ignoring the fact that one human cannot scan 15k images in one hour. Similar use case with medical imagery - seeing the things that are not yet detectable by human eyes.
