Learning Discriminative and Generalizable Anomaly Detector for Dynamic Graph with Limited Supervision
Researchers propose a novel framework for detecting anomalies in dynamic graphs using limited labeled data, combining residual representation encoding with a bi-boundary optimization strategy to balance discrimination and generalization. The model-agnostic approach addresses the gap between unsupervised methods (which produce ambiguous boundaries) and semi-supervised methods (which overfit to limited anomalies).

AgensFlow: A Coordination-Policy Substrate for Multi-Agent Systems
AgensFlow is an open-source framework that treats multi-agent LLM coordination as a learnable policy problem rather than a fixed pipeline, enabling dynamic routing decisions across skill protocols, agent roles, and model bindings. Evaluated on distributed systems and security tasks, the framework demonstrates that learned coordination outperforms static designs while reducing exploration costs through warm-started policy graphs.
