Abstract
The paper introduces Attention-Aware Routing (AAR) to enhance routing in Mixture-of-Experts models by incorporating attention weights, leading to improved performance and insights into the interaction between routing and attention.
Reality Card
Core Claim
AAR improves performance on GSM8K by +3.37 percentage points over a routing-only SFT baseline while isolating routing as the sole variable.
Method / Result
AAR reduces long diverging generation, with incorrect answers getting shorter while correct answers remain unchanged in length.
Limitations
The method is strongly depth-sensitive, and indiscriminate application across layers can degrade factual retrieval.
