RuleSafe-VL: Evaluating Rule-Conditioned Decision Reasoning in Vision-Language Content Moderation

Zhifeng Lu, Dianyuan Wang, Yuhu Shang +1

Platform content moderation applies explicit policy rules and context-dependent conditions to decide whether user content is allowed, restricted, or removed. A correct moderation o…

S-Attention:Attention-Aligned Endogenous Retrieval for Memory-Bounded Long-Context Inference

Qingsen Ma, Dianyun Wang, Yaoye Wang +7

Large language models are increasingly applied to multi-document and long-form inputs, yet long-context inference remains memory- and noise-inefficient. Key-value (KV) caching scal…

Interpretable Safety Alignment via SAE-Constructed Low-Rank Subspace Adaptation

Dianyun Wang, Qingsen Ma, Yuhu Shang +5

Safety alignment -- training large language models (LLMs) to refuse harmful requests while remaining helpful -- is critical for responsible deployment. Prior work established that…

CIP: A Plug-and-Play Causal Prompting Framework for Mitigating Hallucinations under Long-Context Noise

Qingsen Ma, Dianyun Wang, Ran Jing +2

Large language models often hallucinate when processing long and noisy retrieval contexts because they rely on spurious correlations rather than genuine causal relationships. We pr…

Unlocking the Address Book: Dissecting the Sparse Semantic Structure of LLM Key-Value Caches via Sparse Autoencoders

Qingsen Ma, Dianyun Wang, Jiaming Lyu +8

The Key-Value (KV) cache is the primary memory bottleneck in long-context Large Language Models, yet it is typically treated as an opaque numerical tensor. In this work, we propose…
