GoTTA be Diverse: Rethinking Memory Policies for Test-Time Adaptation

Shyma Alhuwaider, Yasmeen Alsaedy, Merey Ramazanova +2

Test-time adaptation (TTA) enables a pre-trained model to adapt online to an unlabeled test stream under distribution shift. While most TTA research focuses on the adaptation objec…
