Dynamic Optimization and Safety Indicator Injection for Jailbreaking Text-to-Image Models with Multimodal Safety Filters

Zixuan Chen, Hao Lin, Ke Xu +2

Text-to-image (T2I) models can generate not-safe-for-work (NSFW) content, motivating multi-stage safety pipelines with both text and image filters. Newer LLM-based filters detect l…

Reactivation: Empirical NTK Dynamics Under Task Shifts

Yuzhi Liu, Zixuan Chen, Zirui Zhang +2

The Neural Tangent Kernel (NTK) offers a powerful tool to study the functional dynamics of neural networks. In the so-called lazy, or kernel regime, the NTK remains static during t…
