🚨 Agentic Systems in Radiology

Everyone’s talking about agents🕵️‍♀️🕵️‍♂️ — but what happens when you bring them into real clinical workflows?

Our new preprint explores the design, applications, challenges, and evaluation of LLM-based agents and agentic workflows in radiology 👇

💥 We unveil our paper accepted at the #ACL2025 Main Conference:
Automated Structured Report Generation

Let's revisit automated radiology report generation for CXR.
Free-form reports make it hard for AI systems to learn accurate generation, and even harder to evaluate. 🧵👇

👍 If you're interested in #LLMs in #radiology, this is a recommended read!

💯 While the article focuses primarily on LLMs, as the authors recommended, "Keep an eye on [large multimodal models]".

When reading AI benchmarks, aside from the fact that many of the AIs are (accidentally or on purpose) trained on the test set, many tests are just bad. MMLU likely maxes out at 90% or so because so many of the questions in it are just wrong. It is also uncalibrated in difficulty across questions.

lot of folks talking about MCP and developers rushing to support it - but it does seem a bit like hype-y.

230. MCP - It's Hot, But Will It Win?
There's a long history of "middleware" in our industry. Everyone wants it. There's always a hot one, but it rarely makes to the finish line and often disappoints.

With the release of new AI models that are better at coding, developers are increasingly using AI to generate code. One of the newest examples is the current batch of Y Combinator, the storied Silicon Valley startup accelerator. A quarter of the W25…

The Illustrated DeepSeek-R1

Spent the weekend reading the paper and sorting through the intuitions. Here's a visual guide and the main intuitions to understand the model and the process that created it.

People: please don't ML for the sake of ML.

I keep seeing manuscripts using fancy machine learning on brain-imaging data, where, in my opinion (having processed a lot of brain-imaging data), the method is way too complex for the richness of the data.

Fancier is not better per se

"productization requires [standardization in development and deployment], which is antithetical to research. [...] PhDs are supposed to come up with innovative ideas, validate these ideas, report the findings to the community by writing papers and then move on."

VLMs go MoE ✨

DeepSeek AI dropped three new commercially permissive vision LMs based on SigLIP encoder and their DeepSeek-MoE decoder 🐳

the models come in 1.0B, 2.8B and 4.5B active params 🥹 models seem to catch up with state-of-the-art with less active parameters! huggingface.co/collections/...
