UniMoMo framework compresses MoE recommendation models for faster inference

By PulseAugur Editorial · [2 sources] ·

Researchers have developed UniMoMo, a post-training compression framework designed to accelerate large recommendation models that utilize mixture-of-experts (MoE) layers. This method groups experts based on their functional similarity rather than parameter distance, using unlabeled calibration data to assess how similarly experts respond to recommendation states. UniMoMo also incorporates a layer-adaptive protection mechanism to prevent performance degradation by restricting the merging of high-traffic experts. Experiments on datasets like Amazon Beauty, KuaiRec, and TenRec demonstrated that compressing MoE models to fewer experts significantly increased inference speedups while maintaining high recommendation quality. AI

IMPACT This research offers a practical method for reducing the computational cost of large recommendation models, potentially enabling wider deployment and faster user experiences.
