New DECAF method enhances machine unlearning by disrupting data clusters

Researchers have introduced DECAF, a novel post-hoc machine unlearning method designed to enhance privacy and adaptive deployment by specifically targeting and disrupting residual feature-space structures associated with forgotten data. Unlike existing methods, DECAF operates solely on the forget set, combining input noise, confidence suppression, and entropy-based output diversification to effectively break clustering attacks. In experiments on CIFAR-10 using ResNet-18, DECAF achieved a forget-class accuracy of 0.10% and a retain accuracy of 79.4%, demonstrating superior performance and efficiency compared to other baselines.
