GRPO-TTA reformulates test-time adaptation for vision-language models as group-wise policy optimization via top-K sampling from CLIP distributions and alignment/dispersion rewards to tune the visual encoder.
ADAPT reframes test-time adaptation as probabilistic Gaussian inference with CLIP-guided regularization, delivering SOTA results without gradients, source data, or full target access in both online and transductive settings.
