New LITE strategy accelerates LLM pre-training by enhancing flat-direction dynamics

Researchers have developed a new acceleration strategy called LITE to improve the efficiency of Large Language Model (LLM) pre-training. LITE enhances training dynamics by applying larger damping coefficients and learning rates along the flat directions of the optimization landscape, which are crucial for loss reduction. This method has been shown to significantly speed up optimizers like Muon and SOAP across various model architectures, parameter scales, and datasets, offering a principled approach to more efficient LLM pre-training.
