New training method boosts CNN robustness against context shift

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new training framework to enhance the robustness of convolutional neural networks against context shift, a phenomenon where diverse test-time environments degrade model performance. The proposed method uses spatial feature attribution to guide models towards object-relevant features rather than non-causal contextual cues. This involves a novel attribution variant called ContrastiveCAMs and a modified loss function, Context-Regularized Cross-Entropy (CR-CE), which suppresses the influence of contextual regions. The approach demonstrated consistent improvements in context-shift robustness across several datasets, including Waterbirds, Spawrious, and ImageNet variants. AI

IMPACT Enhances the reliability of image classification models in real-world, unpredictable environments.

    Improving Context-Shift Robustness of Convolutional Networks via Context-Regularized Cross-Entropy

    arXiv:2611.08157v1 Announce Type: cross Abstract: Image classification models often encounter objects in diverse and unpredictable contexts at test time, which may differ substantially from those seen during training. This phenomenon, termed context shift, exposes a key fragility…
