arXiv:2605.28057v1 Announce Type: new Abstract: Test-time adaptation (TTA) aims to adapt models to maintain reliable performance on non-stationary test streams without requiring labeled data. Despite its empirical success, the learnability of TTA under non-stationary streams remains unexplored. A key challenge is the lack of a principled theoretical framework that simultaneously aligns with the TTA objective and captures both continuously evolving distribution shifts and intrinsic information constraints. To address this gap, we propose the first theoretical framework for studying the learnabi
The proliferation of AI models in real-world, dynamic environments necessitates robust adaptation strategies, making theoretical understanding of test-time adaptation crucial.
A principled theoretical framework for test-time adaptation can accelerate the development of more reliable and generalizable AI systems, moving beyond empirical success to foundational understanding.
The theoretical foundation for understanding how AI models can continuously adapt to new data without retraining changes, enabling more robust and practical AI deployments.
