COLLATOR: Compositional Multi-Agent Orchestration with Counterfactual Reinforcement Learning

Xudong Chen, Yixin Liu, Hua Wei +1

Large language models (LLMs) provide a flexible foundation for multi-agent systems, but their effectiveness and computational cost depend critically on orchestration design. Across…

Bridging Modalities, Spanning Time: Structured Memory for Ultra-Long Agentic Video Reasoning

Jiazheng Li, Chi-Hao Wu, Yunze Liu +3

Understanding ultra-long videos such as egocentric recordings, live streams, or surveillance footage spanning days to weeks, remains a challenge. For current multimodal LLMs: even…

Generalizing GNNs with Tokenized Mixture of Experts

Xiaoguang Guo, Zehong Wang, Jiazheng Li +5

Deployed graph neural networks (GNNs) are frozen at deployment yet must fit clean data, generalize under distribution shifts, and remain stable to perturbations. We show that stati…

Explainable and Fine-Grained Safeguarding of LLM Multi-Agent Systems via Bi-Level Graph Anomaly Detection

Junjun Pan, Yixin Liu, Rui Miao +5

Large language model (LLM)-based multi-agent systems (MAS) have shown strong capabilities in solving complex tasks. As MAS become increasingly autonomous in various safety-critical…

Task Vectors, Learned Not Extracted: Performance Gains and Mechanistic Insight

Haolin Yang, Hakaze Cho, Kaize Ding +1

Large Language Models (LLMs) can perform new tasks from in-context demonstrations, a phenomenon known as in-context learning (ICL). Recent work suggests that these demonstrations a…

Tackling Fake Forgetting through Uncertainty Quantification

Yingdan Shi, Sijia Liu, Kaize Ding +1

Machine unlearning seeks to remove the influence of specified data from a trained model. While the unlearning accuracy provides a widely used metric for assessing unlearning perfor…

Towards Self-Interpretable Graph-Level Anomaly Detection

Yixin Liu, Kaize Ding, Qinghua Lu +3

Graph-level anomaly detection (GLAD) aims to identify graphs that exhibit notable dissimilarity compared to the majority in a collection. However, current works primarily focus on…
