Mitigating Spurious Correlation with Sample Clusterness

This paper addresses the problem of spurious correlations in deep learning models, a significant issue that can lead to poor generalization. The proposed data-oriented approach, which leverages the 'clusterness' of samples influenced by spurious features, offers a novel perspective. The pipeline of identifying, neutralizing, eliminating, and updating is well-defined and provides a clear methodology. The reported improvement in worst group accuracy (over 20%) compared to ERM is a strong indicator of the method's effectiveness. The availability of code and checkpoints enhances reproducibility and practical application.
