LIMSSR: A New Method for Scoring Actions with Missing Modalities

机器之心 · wechat · 2026-07-10

A joint team from Peking University (led by Peng Yuxin) and Fuzhou University (led by Ke Xiao) proposed LIMSSR for incomplete multimodal action quality assessment when modalities are missing during the training phase. The paper has been accepted as a Spotlight at ICML 2026, and the code is now open-source.

The method reformulates the task as conditional sequence inference for "partially observed scores": it first uses prompt-guided, context-aware modality completion to infer missing semantic modalities, then aggregates evaluation information through multi-dimensional fusion tokens, and finally balances the LLM's semantic reasoning with statistical recovery via mask-aware dual-path aggregation.
