Boosting Adversarial Robustness with CLAT: Criticality Leveraged Adversarial Training

ICML 2025poster

Adversarial training (AT) enhances neural network robustness. Typically, AT updates all trainable parameters, but can lead to overfitting and increased errors on clean data. Research suggests that fine-tuning specific parameters may be more effective; however, methods for identifying these essential…
