Researchers are developing advanced techniques for test-time adaptation (TTA) to improve the robustness of large language models (LLMs) under distribution shifts. One approach, Distributional Hypernetworks, predicts distributions over weight updates rather than point estimates, enabling better adaptation and test-time scaling by sampling multiple adapted models. Another method, Misclassification Aware Rank-Limited Adaptation (MARLA), focuses on improving worst-group performance without explicit subgroup annotations by identifying and correcting errors in low-dimensional subspaces. Additionally, Conformal Prediction Active TTA (CPATTA) and WISE-ATTA address the efficiency of active TTA, with CPATTA using principled conformal uncertainty for better data selection and WISE-ATTA focusing on when to request labels within a budget to optimize supervision allocation.
