arXiv:2606.26457v1 Announce Type: cross Abstract: This paper presents a probabilistic framework for online test-time adaptation problems. In them, a model is trained on labeled data but must adapt to unlabeled data at test time under the assumption that training and test distributions potentially differ, that is, there might have been a distributional shift. The framework is based on a state-space modelling architecture from which parameter learning, parameter time evolution, prior tuning, and prediction can be characterized.
The increasing deployment of AI models in real-world scenarios highlights the immediate need for robust adaptation mechanisms to handle distributional shifts, which are common in dynamic environments.
This probabilistic framework offers a systematic approach to online test-time adaptation, critical for ensuring the reliability and effectiveness of AI systems in production under varying data conditions.
The ability of AI models to adapt more effectively to unseen, unlabeled data at test-time under distributional shifts becomes more formalized and robust than previous heuristic approaches.
