New framework tackles backdoor attacks in continual learning

Researchers have introduced a novel framework for continual learning that addresses the challenge of backdoor attacks in sequentially arriving tasks. This framework integrates sample purification, selective recovery, and robust expert routing to mitigate catastrophic forgetting, maintain adaptation, and prevent the absorption of malicious supervision. The proposed methods include Bi-Prototype Purification (BPP) for identifying suspicious samples, Gradient Discrepancy-based Robustness Optimization (GDBRO) for selective recovery and pseudo-label correction, and Robust Feature Consistency-based Expert Selection (RFCBES) for reliable expert routing.
