In this paper, researchers tackle the problem of machine learning model robustness under distribution shifts by adapting models during inference without access to labels. The authors investigate optimal hyperparameter selection for existing Test-Time Adaptation (TTA) methods using surrogate-based strategies that don’t require test label access. They find that state-of-the-art TTA methods perform poorly when evaluated realistically, and that forgetting remains a problem in TTA. The study highlights the importance of rigorous benchmarking and model selection strategies, making their code open-source to facilitate further research.

This paper helps us make machine learning models more robust by adapting them during use without needing any labels. It’s like fine-tuning a car to drive well on different roads! The researchers tried different ways to choose the best settings for these adaptations and found that some methods don’t work as well when tested in a realistic way. They also discovered that it’s still easy for the models to forget what they learned. To make things better, the authors are sharing their code so others can build on their work.
