🧠🤖 Foundation models are shaking up medical imaging! @Neda_TV et al show how these models streamline workflows, boost accuracy, personalize care, & generate synthetic images. For real impact, we need trust, explainability, & integration! #AI #Radiology pubs.rsna.org/doi/10.1148/ra…

So much controversy triggered by claims about how humans learn. But the deeper question is why the way we learn works. We need to understand the why to know in what way “how” matters. Nature is inspiration for AI, not prescription. The crux of the whole debate is abstraction. Underneath all learning is representation. The key question is not whether there is a “world model” or whether there is imitation or not. The instrumental question is, what kind of representation does the learning mechanism produce? And then, what are all the leaning mechanisms, natural or not, that can produce good representations?

.@RichardSSutton, father of reinforcement learning, doesn’t think LLMs are bitter-lesson-pilled. My steel man of Richard’s position: we need some new architecture to enable continual (on-the-job) learning. And if we have continual learning, we don't need a special training phase - the agent just learns on-the-fly - like all humans, and indeed, like all animals. This new paradigm will render our current approach with LLMs obsolete. I did my best to represent the view that LLMs will function as the foundation on which this experiential learning can happen. Some sparks flew. 0:00:00 – Are LLMs a dead-end? 0:13:51 – Do humans do imitation learning? 0:23:57 – The Era of Experience 0:34:25 – Current architectures generalize poorly out of distribution 0:42:17 – Surprises in the AI field 0:47:28 – Will The Bitter Lesson still apply after AGI? 0:54:35 – Succession to AI

Shoutout to CBP for handcuffing me and my wife at the border. No warning, no reason, just a “you matched a profile” (explained after the cuffs, of course). Cut the science, cuff the scientists!🇺🇸 #MAGA #BorderPatriotism

Advanced Prostate Cancer Consensus Conference
Physics-Informed Autoencoder for Prostate Tissue Microstructure Profiling with Hybrid Multidimensional MRI The Physics-Informed Autoencoder (PIA) is a self-supervised deep learning model🤖 that accurately and efficiently measures prostate tissue biomarkers using hybrid multidimensional MRI, outperforming traditional nonlinear least squares (NLLS) methods. By embedding a biophysical diffusion-relaxation model into a neural network, PIA achieves high agreement with histopathology🔬across epithelium, stroma, and lumen compartments, even under noisy conditions. In both in silico and in vivo validation, PIA demonstrated strong correlations with prostate cancer aggressiveness and delivered results up to 10,000 times faster than NLLS. These findings highlight PIA's promise as a robust, noninvasive, and explainable tool for #ProstateCancer detection and characterization. @ulasbagci @UChicagoRADS @NURadiology #MRI #AI #MachineLearning @OncoAlert 🚨 @nataliagandur @bavilima @Silke_Gillessen @AOmlin

🚀 Introducing our proceedings on efficient MedSAMs in CVPR2024! Promptable segmentation foundation models are revolutionizing medical imaging, yet their high computational demands hinder clinical adoption. To address this, we launched the first international competition in CVPR 2024 on efficient segmentation foundation models. 🏆 Key highlights: 🔹A large-scale benchmark spanning nine imaging modalities from 20+ institutions. 🔹Top teams developed lightweight segmentation models with efficient inference pipelines, dramatically reduced computational costs while maintaining state-of-the-art accuracy. 🔹 The best-performing algorithms are now integrated into open-source 3D Slicer software with a user-friendly interface to bridge research and clinical practice. Proceedings: link.springer.com/book/10.1007/9… Summary: arxiv.org/abs/2412.16085

An effective day brainstorming and learning - for both the scholars & the mentors As our guest lecturer @ulasbagci says " AI will not replace physicians, but physicians who learn AI will replace them in healthcare research" Thanks @ASGEendoscopy ! -with @AliSoroushMD
