Using AI for anomaly detection is nothing new though. Haven't read any article about this specific 'discovery' but usually this uses a completely different technique than the AI that comes to mind when people think of AI these days.

    That's why I hate the term AI. Say it is a predictive llm or a pattern recognition model.

    Say it is a predictive llm

    According to the paper cited by the article OP posted, there is no LLM in the model. If I read it correctly, the paper says that it uses PyTorch's implementation of ResNet18, a deep convolutional neural network that isn't specifically designed to work on text. So this term would be inaccurate.

    or a pattern recognition model.

    Much better term IMO, especially since it uses a convolutional network. But since the article is a news publication, not a serious academic paper, the author knows the term "AI" gets clicks and positive impressions (which is what their job actually is) and we wouldn't be here talking about it.

    Well, this is very much an application of AI... Having more examples of recent AI development that aren't 'chatgpt'(/transformers-based) is probably a good thing.

    Op is not saying this isn't using the techniques associated with the term AI. They're saying that the term AI is misleading, broad, and generally not desirable in a technical publication.

    Correct, also not what I was replying about. I said that using AI in the headline here is very much correct. It is after all a paper using AI to detect stuff.

    it's a good term, it refers to lots of thinks. there are many terms like that.

    So it's a bad term.

    It's literally the name of the field of study. Chances are this uses the same thing as LLMs. Aka a neutral network, which are some of the oldest AIs around.

    It refers to anything that simulates intelligence. They are using the correct word. People just misunderstand it.

    The problem is that it refers to so many and constantly changing things that it doesn't refer to anything specific in the end. You can replace the word "AI" in any sentence with the word "magic" and it basically says the same thing...

    From the conclusion of the actual paper:

    Deep learning models that use full-field mammograms yield substantially improved risk discrimination compared with the Tyrer-Cuzick (version 8) model.

    If I read this paper correctly, the novelty is in the model, which is a deep learning model that works on mammogram images + traditional risk factors.

    For the image-only DL model, we implemented a deep convolutional neural network (ResNet18 [13]) with PyTorch (version 0.31; pytorch.org). Given a 1664 × 2048 pixel view of a breast, the DL model was trained to predict whether or not that breast would develop breast cancer within 5 years.

    The only "innovation" here is feeding full view mammograms to a ResNet18(2016 model). The traditional risk factors regression is nothing special (barely machine learning). They don't go in depth about how they combine the two for the hybrid model, so it's probably safe to assume it is something simple (merely combining the results, so nothing special in the training step). edit: I stand corrected, commenter below pointed out the appendix, and the regression does in fact come into play in the training step

    As a different commenter mentioned, the data collection is largely the interesting part here.

    I'll admit I was wrong about my first guess as to the network topology used though, I was thinking they used something like auto encoders (but that is mostly used in cases where examples of bad samples are rare)

    Actually they did, it's in Appendix E (PDF warning) . A GitHub repo would have been nice, but I think there would be enough info to replicate this if we had the data.

    Yeah it's not the most interesting paper in the world. But it's still a cool use IMO even if it might not be novel enough to deserve a news article.

    I skimmed the paper. As you said, they made a ML model that takes images and traditional risk factors (TCv8).

    I would love to see comparison against risk factors + human image evaluation.

    Nevertheless, this is the AI that will really help humanity.
