DBES: A Systematic Benchmark and Metric Suite for Evaluating Expert Specialization in Large-Scale MoEs
DBES supplies a multi-domain benchmark and five metrics (Routing Specialization, Normalized Effective Rank, Domain Isolation, Routing Stiffness Score, N-gram Expertise) that reveal distinct specialization patterns across MoE models and enable 66-94% domain gains with 15% training resources.
