Researchers have developed EPnG, a novel framework for parameter-efficient fine-tuning of Mixture-of-Experts (MoE) models. This method adaptively reallocates fine-tuning capacity by pruning under-utilized experts and growing high-importance ones, guided by router gate probabilities. EPnG demonstrates superior performance compared to standard LoRA methods on MoE architectures like OLMoE and Qwen1.5-MoE, achieving results comparable to full fine-tuning while updating a significantly smaller fraction of parameters.
