Did you know our Open Science community has an ML Math group led by @KatrinaL2899 and @neel_ghoshal? 🔢 This group dives into the math that powers machine learning and deep learning, exploring topics like Implicit Differentiation, Gradient vs Jacobian vs Hessian Matrix, Solving Equations Analytically vs Numerically and many more! Whether you're brushing up on fundamentals or digging deeper into the math behind AI and LLMs, all skill levels are welcome. ✨ 📹 Check out some of their resources including these ones on YouTube: youtube.com/watch?v=DXNCBu… youtube.com/watch?v=JxyAD5…

Modern ML optimizers aren’t just update rules, they’re sophisticated ways of navigating complex loss geometry. My latest video with @Cohere_Labs breaks down the evolution from SGD to OLion through the lens of Taylor approximations. Watch here: youtu.be/DXNCBu1mSYM #AI #ML

Taylor Series aren’t just a calculus topic, they’re foundational to ML optimization. My latest video with @Cohere_Labs breaks down how local approximations of loss functions lead to Gradient Descent and Newton’s Method. Watch here: youtu.be/ALP1J81Sqxw #MachineLearning #AI

🔢 @KatrinaL2899 has been leading the ML Math Group for two years and brings so much enthusiasm to everything she does. From participating in multiple Expeditions to hosting one of our biggest ML Summer School sessions on math, Katrina’s passion for the field is clear. She’s even launched her own YouTube channel focused on all things math - an extension of the dedication she brings to the community.

On Feb 28, six planets will appear to line up. But they aren’t actually aligned. They orbit on nearly the same geometric plane. From Earth, projecting that 3D plane onto our 2D sky makes it look like a straight line. YouTube: youtube.com/shorts/ojiDMo0… #math #Astronomy @NASA
