Ripple-Pivot Search: Active Parallel Decoding for Diffusion Large Language Models

Yushi Ye, Xu Chen, Haoyun Jiang +7

Diffusion Large Language Models (dLLMs) have emerged as a competitive alternative to autoregressive language models, offering the potential for substantially faster inference throu…

SkillDAG: Self-Evolving Typed Skill Graphs for LLM Skill Selection at Scale

Tong Bai, Zhenglin Wan, Pengfei Zhou +3

As LLM agents adopt large skill libraries, selecting the right subset becomes a structural problem rather than a similarity-matching one: skills depend on, conflict with, specializ…

Don't Blindly Trust It: How Unreliable Feedback Breaks Tool-Using LLM Agents

Chubin Zhang, Zhenglin Wan, Xingrui Yu +5

Tool-augmented agents are typically evaluated by their gains under reliable external feedback. Yet these gains leave open a key counterfactual: when feedback is unreliable, would t…

Calibration Is Not Control: Why LLM-Agent Oversight Needs Intervention

Chubin Zhang, Zhenglin Wan, Xingrui Yu +5

Runtime oversight for LLM agents is commonly framed as scalar risk prediction: estimate failure likelihood, confidence, or uncertainty, then intervene once the score crosses a thre…

Training Diffusion Policies via Prior-Mapping Co-Evolution

Chubin Zhang, Zhenglin Wan, Feng Chen +7

Reinforcement learning (RL) faces a persistent tension: policies that are stable to optimize (e.g., Gaussians) are often too simple to represent the multimodal action distributions…

Plug-and-Adapt: Multimodal Coreference Resolution at First Sight with a Pretrained Alignment Model

Jinghan Wu, Jing Li, Ivor W. Tsang +1

Visual information helps resolve ambiguity in coreference resolution, leading to notable performance gains. However, existing Multi-modal Coreference Resolution (MCR) methods requi…
