From Knowledge Access to Source Learning: Developing Source-Specific Competence

Lucheng Fu, Kejing Xia, Yiyang Wang +10

Large language model (LLM) agents increasingly rely on persistent external sources to solve sequences of knowledge-intensive tasks. Existing methods improve how source content is a…

Made to Measure: Designing Image Watermarks to Specification

Mingzhe Li, Yuefeng Peng, Kejing Xia +3

Image watermarking supports provenance and attribution by embedding verifiable identity information into images. Practical deployments, however, must jointly satisfy requirements f…

ChainSWE: Benchmarking Coding Agents on Multi-Bug Software Maintenance

Qirui Jin, Lingching Tung, Kenan Li +12

Language model (LM) agents are increasingly deployed to maintain codebases over extended periods, fixing streams of related defects while carrying context from one fix to the next.…

PACT: Privileged Trace Co-Training for Multi-Turn Tool-Use Agents

Zhenbang Du, Jun Luo, Zhiwei Zheng +8

Multi-turn tool-use agents must reason, call tools, and adapt to observations across several interaction turns. Post-training such agents is challenging, as reinforcement learning…

-dLLM: Accelerating Diffusion Large Language Models via Spatio-Temporal Redundancy Reduction

Zhenbang Du, Kejing Xia, Xinrui Zhong +6

Diffusion Large Language Models (dLLMs) have emerged as a promising alternative to autoregressive generation by enabling parallel token prediction. However, practical dLLM decoding…

CopT: Contrastive On-Policy Thinking with Continuous Spaces for General and Agentic Reasoning

Dachuan Shi, Hanlin Zhu, Xiangchi Yuan +4

Chain-of-thought (CoT) is a standard approach for eliciting reasoning capabilities from large language models (LLMs). However, the common CoT paradigm treats thinking as a prerequi…

Membership Inference Attacks on Vision-Language-Action Models

Yuefeng Peng, Mingzhe Li, Kejing Xia +2

Membership inference attacks (MIAs) have been extensively studied in large language models (LLMs) and vision-language models (VLMs), yet their implications for vision-language-acti…

MetaState: Persistent Working Memory Enhances Reasoning in Discrete Diffusion Language Models

Kejing Xia, Mingzhe Li, Lixuan Wei +5

Discrete diffusion language models (dLLMs) generate text by iteratively denoising a masked sequence. However, standard dLLMs condition each denoising step solely on the current har…

DGS: Dense Depth Regularization for LiDAR-free Urban Scene Reconstruction

Kejing Xia, Jidong Jia, Ke Jin +4

Recently, Gaussian Splatting (GS) has shown great potential for urban scene reconstruction in the field of autonomous driving. However, current urban scene reconstruction methods o…
