When Are Experts Misrouted? Counterfactual Routing Analysis in Mixture-of-Experts Language Models

Youngsik Yoon, Siwei Wang, Wei Chen +1

Mixture-of-Experts (MoE) language models route each token to a small subset of experts, but whether the routes selected by a trained top- router are good ones is rarely evaluate…
