PEC-Home (RAG) - Multi-User Level 4: leaderboard

Smart-home command interpretation in PEC-Home (Shan et al., 2026), multi-user scenario, where household members expect different settings: commands at ellipsis level 4 of 4, which leave out the room, device or operation established earlier, with the model given the three most relevant earlier commands and responses retrieved from the dialogue history. Execution accuracy in percent, the share of commands mapped to the intended device operations; higher is better.

Metric: Execution accuracy (%; 1,068 smart-home commands at ellipsis level 4 of 4 (progressively elliptical), functionally correct device operations; dialogue history retrieved from a vector store, top-3). Source: arxiv.org. Saturation forecast: Estimated already saturated. 10 models tracked.
