Researchers have developed a new theoretical framework for understanding and improving large language model (LLM) optimizers, moving beyond empirical tuning to a physics-inspired model. This approach treats the LLM's weight matrix as a responsive medium with memory, providing answers to why certain update rules like Muon are effective and how long momentum should be averaged. Based on this model, they propose the Bi-Maxwell optimizer, which incorporates a two-timescale memory kernel and has shown improved training efficiency on LLM benchmarks. AI
