Finding and Fixing Spurious Patterns with Explanations
Authors that are also TMLR Expert Reviewers: ~Gregory_Plumb2
Abstract: Image classifiers often use spurious patterns, such as “relying on the presence of a person to detect a tennis racket,” which do not generalize. In this work, we present an end-to-end pipeline for identifying and mitigating spurious patterns for such models, under the assumption that we have access to pixel-wise object-annotations. We start by identifying patterns such as “the model’s prediction for tennis racket changes 63% of the time if we hide the people.” Then, if a pattern is spurious, we mitigate it via a novel form of data augmentation. We demonstrate that our method identifies a diverse set of spurious patterns and that it mitigates them by producing a model that is both more accurate on a distribution where the spurious pattern is not helpful and more robust to distribution shift.
