Does More Retrieved Evidence Help Visual Retrieval-Augmented Generation with Diffusion Language Models?

Jiankun Wang, Yisen Gao, Ziwei Zhang +3

Visual retrieval-augmented generation (RAG) commonly expands the retrieved evidence set to improve answer-page coverage, implicitly assuming that all available evidence should be p…

MAFIA: Query-Only Memory Attacks via Probing and Factual Injection against Audited LLM Agents

Jiaming Chen, Yisen Gao, Yanping Li +3

Memory-augmented LLM agents rely on rich context for long-horizon reasoning and acting, yet their memory modules expose a persistent attack surface for malicious records, making th…

PatchWorld: Gradient-Free Optimization of Executable World Models for Agent Environments

Jiaxin Bai, Yue Guo, Yifei Dong +13

World models for interactive text agents must typically be learned from observation-action trajectories alone. Specifically, the environment returns text observations after each ac…

SING: Synthetic Intention Graph for Scalable Active Tool Discovery in LLM Agents

Qiao Xiao, Haochen Shi, Yisen Gao +9

Large language model (LLM) agents increasingly rely on agent harnesses that manage context, tools, and multi-turn execution, making tools a central interface for acting in realisti…

HypoAgent: An Agentic Framework for Interactive Abductive Hypothesis Generation over Knowledge Graphs

Yisen Gao, Yixi Cai, Tianshi Zheng +2

Abductive reasoning over knowledge graphs aims to generate logical hypotheses that explain observed entities or facts. Existing controllable hypothesis generation methods allow use…

NGDBench: Towards Neural Graph Data Management

Yufei Li, Yisen Gao, Jiaxuan Xiong +6

Data critical to real-world decision-making is increasingly found within organizations. Such data is heterogeneous, constantly evolving, and only imperfectly captured. However, cur…
