Researchers have developed MESH, a novel optimization technique designed to improve the efficiency of training Mixture-of-Experts (MoE) models. Traditional memory-efficient optimizers like Sinkhorn struggle with MoE architectures due to the conditional and varying nature of their gradients. MESH introduces a hidden-momentum Sinkhorn update that preserves temporal first-moment signals, reducing optimizer state memory by approximately 62.5% and peak PyTorch CUDA allocation by about 12.6% compared to AdamW, while maintaining competitive evaluation loss.
