arXiv:2606.15730v1 Announce Type: cross Abstract: Backdoor unlearning aims to remove a malicious trigger behavior from a deployed model while preserving clean utility. We study the update-free inference-time setting, where model parameters remain frozen. First, we audit a common projection assumption under oracle paired clean and triggered features. Projection succeeds mainly on BadNets and leaves WaNet, Blended, and SIG at 0.683, 0.888, and 0.941 ASR on CIFAR-10 ResNet-18. This failure is not explained by spectral compactness, spatial locality, or subspace misalignment. It is predicted by a l
This research addresses a critical and evolving challenge in AI security, particularly relevant as AI models are increasingly deployed in sensitive applications.
A strategic reader should care about advancements in backdoor unlearning as it directly impacts the trustworthiness and reliability of AI systems, especially in defence and critical infrastructure.
This research introduces 'InstantForget' as a novel, update-free method to mitigate backdoor threats, which could improve the resilience of deployed AI models.
