Leveraging Gradients for Unsupervised Accuracy Estimation under Distribution Shift

no code implementations17 Jan 2024 Renchunzi Xie, Ambroise Odonnat, Vasilii Feofanov, Ievgen Redko, Jianfeng Zhang, Bo An

Our key idea is that the model should be adjusted with a higher magnitude of gradients when it does not generalize to the test dataset with a distribution shift.
