GLASS: Graph-Language Alignment with Spherical Scoring for Transferable Graph-Level Anomaly Detection

Xudong Wang, Chris Ding, Tongxin Li +1

We introduce GLASS, a framework for graph-level anomaly detection (GLAD) that achieves robust cross-domain transferability through graph-language alignment on the unit hypersphere.…

The Retriever Should Remember: Experience-Amortized Reranking for Long-Term Agent Memory

Qi Feng, Chris Ding, Jicong Fan

Long-term language-model agents accumulate memories across interactions, but their retrievers typically do not accumulate retrieval experience. Semantic retrieval is efficient, but…

Mapping and Measuring the Behavioral Evolution of Large Language Models

Dong Qiao, Chris Ding, Jicong Fan

Benchmark leaderboards summarize how well a language model performs, but not how its behavior relates to that of other models or changes across generations. We characterize the out…
