Learning to Learn-at-Test-Time: Language Agents with Learnable Adaptation Policies

Zhanzhi Lou, Hui Chen, Yibo Li +2

The paper introduces Meta-TTL, a bi‑level optimization framework that learns adaptation policies for test‑time learning in language agents, using evolutionary search to improve per…

Just-In-Time Reinforcement Learning: Continual Learning in LLM Agents Without Gradient Updates

Yibo Li, Zijie Lin, Ailin Deng +5

While Large Language Model (LLM) agents excel at general tasks, they inherently struggle with continual adaptation due to the frozen weights after deployment. Conventional reinforc…

Generalizing Graph Transformers Across Diverse Graphs and Tasks via Pre-training

Yufei He, Zhenyu Hou, Yukuo Cen +5

Graph pre-training has been concentrated on graph-level tasks involving small graphs (e.g., molecular graphs) or learning node representations on a fixed graph. Extending graph pre…

Enabling Self-Improving Agents to Learn at Test Time With Human-In-The-Loop Guidance

Yufei He, Ruoyu Li, Alex Chen +8

Large language model (LLM) agents often struggle in environments where rules and required domain knowledge frequently change, such as regulatory compliance and user risk screening.…

UniGraph2: Learning a Unified Embedding Space to Bind Multimodal Graphs

Yufei He, Yuan Sui, Xiaoxin He +3

Existing foundation models, such as CLIP, aim to learn a unified embedding space for multimodal data, enabling a wide range of downstream web-based applications like search, recomm…
