RAMP: Reversing Adversarial Perturbations to Strengthen Clean-Label Backdoor Attacks against Malware Detectors

Jinwen Xin, Dongni Zhang, Chenyang Wang وآخرون · 2026

Deep learning-based malware detectors are commonly updated by fine-tuning on newly collected samples, but this practical update pipeline also creates an attack surface for training-time backdoor attacks. In realistic crowdsourced data collection, however, strict label vetting typically restricts attackers to the clean- …

Uncertainty-Guided Sparse Refinement for Action Chunking Transformer Policies

Chenyang Wang, Yuntian Wang, Xiaoxiong Yang وآخرون · 2026

Learning chunk-based visuomotor policies for long-horizon robot manipulation remains challenging. Recent action-chunking methods have shown promising performance by predicting temporally extended action sequences. However, their failures are often dominated by prediction errors at a small number of critical timesteps r …
