Researchers have developed two new methods, LorExperts and BTExperts, for compressing Mixture-of-Experts (MoE) language models. These techniques aim to reduce the computational cost of deploying MoE models by compressing expert weight matrices while preserving accuracy. LorExperts clusters experts and uses a dominant full-precision expert with low-rank corrections for others, retaining the original router. BTExperts further organizes these into a tree structure for amortized computation. Both methods show improved performance over existing baselines, particularly as the number of experts increases, demonstrating their effectiveness in maintaining accuracy with significant compression on models like Qwen3-30B-A3B and Gemma-4-26B-A4B.
