New method reveals spatial shortcut patterns in vision models

Researchers have developed a new method to identify and characterize shortcut learning in vision models by grouping per-image contribution maps into recurring spatial patterns. This approach, utilizing K-means and non-negative matrix factorization, reveals shared and distinct spatial patterns of shortcut and task contributions across various datasets and model architectures like ResNet and ViT. The discovered shortcut groups enable targeted inspection of image subsets with higher error rates, and interventions to suppress shortcut contributions can significantly degrade model performance, suggesting a combined suppression and amplification approach to reduce performance disparities.

    Discovery and Spatial Characterisation of Multiple Shortcut Groups for Auditing Vision Model Bias

    arXiv:2608.14051v1 Announce Type: new Abstract: Deep learning models trained on datasets with spurious correlations can achieve high average accuracy whilst relying on shortcut features that do not generalise out of distribution. Whilst out-of-distribution testing highlights subg…
