Researchers have developed StickyMoE, a new training method for Mixture-of-Experts (MoE) models designed to improve inference efficiency on edge devices. This technique introduces a differentiable routing consistency loss that discourages abrupt expert switches between consecutive tokens, promoting stable expert assignments for semantically related text spans. Unlike previous methods that applied fixes after pretraining, StickyMoE integrates this optimization directly into the training process, allowing routing and expert representations to co-evolve. Experiments demonstrate a significant reduction in expert switching rates, with minimal impact on model perplexity, offering a Pareto-optimal improvement in quality and locality. AI
