SARSteer: Safeguarding Large Audio Language Models via Safe-Ablated Refusal Steering

ICML 2026poster

Large Audio–Language Models (LALMs) are becoming essential as a powerful multimodal backbone for real-world applications. However, recent studies show that audio inputs can more easily elicit harmful responses than text, exposing new risks toward deployment. While safety alignment has made initial a…

BackdoorDM: A Comprehensive Benchmark for Backdoor Learning on Diffusion Model

NeurIPS 2025poster

Backdoor learning is a critical research topic for understanding the vulnerabilities of deep neural networks. While the diffusion model (DM) has been broadly deployed in public over the past few years, the understanding of its backdoor vulnerability is still in its infancy compared to the extensive…

Fusing Pruned and Backdoored Models: Optimal Transport-based Data-free Backdoor Mitigation

AAAI 2025technical

Backdoor attacks present a serious security threat to deep neuron networks (DNNs). Although numerous effective defense techniques have been proposed in recent years, they inevitably rely on the availability of either clean or poisoned data. In contrast, data-free defense techniques have evolved slow…

Gradient Norm-based Fine-Tuning for Backdoor Defense in Automatic Speech Recognition

ICASSP 2025accepted

Backdoor attacks have posed a significant threat to the security of deep neural networks (DNNs). Despite considerable strides in developing defenses against backdoor attacks in the visual domain, the specialized defenses for the audio domain remain empty. Furthermore, the defenses adapted from the v…

Unveiling and Mitigating Backdoor Vulnerabilities based on Unlearning Weight Changes and Backdoor Activeness

NeurIPS 2024poster

The security threat of backdoor attacks is a central concern for deep neural networks (DNNs). Recently, without poisoned data, unlearning models with clean data and then learning a pruning mask have contributed to backdoor defense. Additionally, vanilla fine-tuning with those clean data can help rec…
