🚀 What if particles in a gas could inspire better AI training? Meet FOCUS - our new optimizer that turns physics intuition into speed! By embracing noise like attractive particles, it outperforms Adam in GPT-2 training. Slower particles → Faster learning! 🧵(1/8) arxiv.org/abs/2501.12243

Ever wondered why some ecosystems are stable while others are not? 🌿 Our study reveals the secret: not just about WHAT species eat, but HOW WELL it feeds them! When species feast on things barely help them grow, chaos emerges. Think of it as dining at the wrong restaurant! 🍽️ go.aps.org/3DLN7X4
Complex Ecosystems Lose Stability When Resource Consumption Is Out of Niche
A simple theoretical framework predicts that complex communities lose stability when species consume resources out of their niche.

Double descent in ecosystems: predators = parameters, prey = data?
As a predator, would you prefer fewer or more competitors? Plot twist: it depends on your prey! Our @pnas.org study shows ecosystem stability isn't about having more or fewer species - it's about the diversity gap between predators and prey. Nature keeps surprising us! 🦊🐰 Read full article:
