Reallocating Attention Across Layers to Reduce Multimodal Hallucination

CVPR 2026

Multimodal large reasoning models (MLRMs) often suffer from hallucinations that stem not only from insufficient visual grounding but also from imbalanced allocation between perception and reasoning processes. Building upon recent interpretability findings suggesting a staged division of attention ac

Advancing Expert Specialization for Better MoE

NeurIPS 2025oral

Mixture-of-Experts (MoE) models enable efficient scaling of large language models (LLMs) by activating only a subset of experts per input. However, we observe that the commonly used auxiliary load balancing loss often leads to expert overlap and overly uniform routing, which hinders expert speciali…

Auditing Meta-Cognitive Hallucinations in Reasoning Large Language Models

NeurIPS 2025poster

The development of Reasoning Large Language Models (RLLMs) has significantly improved multi-step reasoning capabilities, but it has also made hallucination problems more frequent and harder to eliminate. While existing approaches address hallucination through external knowledge integration, model pa…

KGMark: A Diffusion Watermark for Knowledge Graphs

ICML 2025poster

Knowledge graphs (KGs) are ubiquitous in numerous real-world applications, and watermarking facilitates protecting intellectual property and preventing potential harm from AI-generated content. Existing watermarking methods mainly focus on static plain text or image data, while they can hardly be ap…
