Tent: Fully Test-time Adaptation by Entropy Minimization
What this work does
Updates normalization statistics and affine parameters online by minimizing prediction entropy on unlabeled target inputs.
Connection to discovery
A compact label-free adaptation baseline and a warning that optimizing confidence differs from acquiring reliable new evidence.
Evidence
Inspected source/target-data access distinctions, corruption-error comparisons and feature-modulation ablations; some embedded figure text is poorly extracted.
Scope and limitations
Entropy can decrease for incorrect predictions. Image-corruption results do not establish usefulness for LLM scientific discovery, especially with new classes or mechanisms.
