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…

Continuous Semantic Caching for Low-Cost LLM Serving

Baran Atalar, Xutong Liu, Jinhang Zuo +3

As Large Language Models (LLMs) become increasingly popular, caching responses so that they can be reused by users with semantically similar queries has become a vital strategy for…

Offline Learning for Combinatorial Multi-armed Bandits

Xutong Liu, Xiangxiang Dai, Jinhang Zuo +4

The combinatorial multi-armed bandit (CMAB) is a fundamental sequential decision-making framework, extensively studied over the past decade. However, existing work primarily focuse…
