WISE-ATTA: When to Ask for Labels in Budgeted Active Test-Time Adaptation
WISE-ATTA treats label requests as a timing problem, not just a sample-picking problem.
The paper defines “budgeted ATTA,” where a deployed model can ask for labels on only some test batches under distribution shift. Its method uses lightweight online signals to decide when supervision is likely to help most, then selects a drift-heavy sample for labeling inside the chosen batch. The authors report competitive or better results on ImageNet-C and ImageNet-R/K/A while using substantially fewer labels than recent active test-time adaptation methods. HF Daily Papers' note
