The result is a fair, end‑to‑end comparison that isolates what actually drives performance for radiology foundation models.

including not just findings but also lines & tubes classification/segmentation and report generation. We also test the effect of adding structured labels alongside reports during CLIP‑style pretraining, and study scaling laws under these controlled conditions.

That makes it hard to tell whether wins come from the model design or just from more data/compute or favorable benchmarks. We fix this by holding the pretraining dataset and compute constant and standardizing evaluation across tasks,

Why this matters: Prior comparisons of radiology encoders have often been apples‑to‑oranges: models trained on different datasets, with different compute budgets, and evaluated mostly on small datasets of finding‑only tasks.

✅ Pretrained on 3.5M CXRs to study scaling laws for radiology models
✅ Compared MedImageInsight (CLIP-based) vs RAD-DINO (DINOv2-based)
✅ Found that structured labels + text can significantly boost performance
✅ Showed that as little as 30k in-domain samples can outperform public foundation models

Data Scaling Laws for Radiology Foundation Models Foundation vision encoders such as CLIP and DINOv2, trained on web-scale data, exhibit strong transfer performance across tasks and datasets. However, medical imaging foundation models remain constrai...

🩻Excited to share our latest preprint: “Data Scaling Laws for Radiology Foundation Models”
Foundation vision encoders like CLIP and DINOv2 have transformed general computer vision, but what happens when we scale them for medical imaging?

Dear computer vision researchers, students & practitioners🔇🔇🔇

Remi Denton & I have written what I consider to be a comprehensive paper on the harms of computer vision systems reported to date & how people have proposed addressing them, from different angles.

Kudos to @blackhc.bsky.social for calling out this neurips oral: openreview.net/forum?id=0NM... for not giving the rho-loss paper (arxiv.org/abs/2206.07137) the recognition it deserves!

In all of the reposts I see of articles criticising generative AI, I still don't see enough mention of work like Dr. Birhane's, which shows the biases against disadvantaged groups in the training datasets.
This is very good.

One of the reasons the university sector has come so spectacularly off the rails is the fact it's so unfriendly to family life, people with caring responsibilities and parents. The attitude is often: 'Not working 24/7? You're not fully committed!'

Medical Adaptation of Large Language and Vision-Language Models: Are We Making Progress? Several recent works seek to develop foundation models specifically for medical applications, adapting general-purpose large language models (LLMs) and vision-language models (VLMs) via continued pret...

Medically adapted foundation models (think Med-*) turn out to be more hot air than hot stuff. Correcting for fatal flaws in evaluation, the current crop are no better on balance than generic foundation models, even on the very tasks for which benefits are claimed.
arxiv.org/abs/2411.04118

What a surprise (not!). Yet again ... poor evaluations of specialized medical LLMs result in overhyped claims relative to the base LLMs. #bioMLeval

Not sure about IRM thought. They early stopped their experiments to get the colored MNIST results.

Good repost would have completely missed this :)

Thanks for the pack! Can you please add me :)

Even as an interpretable ML researcher, I wasn't sure what to make of Mechanistic Interpretability, which seemed to come out of nowhere not too long ago.

But then I found the paper "Mechanistic?" by
@nsaphra.bsky.social and @sarah-nlp.bsky.social, which clarified things.
