From Player to Master: Enhancing Test-Time Learning of LLM Agents via Reinforcement Learning over Memory

ICML 2026poster

Large language model (LLM) agents are increasingly deployed in long-running settings where improving through experience at test time becomes important. A common approach is to update an explicit memory after each interaction to guide future decisions. However, most existing methods rely on hand-desi…

Learning Adaptive Distribution Alignment with Neural Characteristic Function for Graph Domain Adaptation

ICLR 2026poster

Graph Domain Adaptation (GDA) transfers knowledge from labeled source graphs to unlabeled target graphs but is challenged by complex, multi-faceted distributional shifts. Existing methods attempt to reduce distributional shifts by aligning manually selected graph elements (e.g., node attributes or s…

Learning Structure-Semantic Evolution Trajectories for Graph Domain Adaptation

ICLR 2026poster

Graph Domain Adaptation (GDA) aims to bridge distribution shifts between domains by transferring knowledge from well-labeled source graphs to given unlabeled target graphs. One promising recent approach addresses graph transfer by discretizing the adaptation process, typically through the construct…

SynGR: Unleashing the Potential of Cross-Modal Synergy for Generative Recommendation

ICML 2026poster

Generative Recommendation (GR) has emerged as a promising paradigm by formulating item recommendation as a sequence-to-sequence generation task over item identifiers. Recent studies have incorporated multimodal signals to provide richer token-level evidence for generation. However, existing approach…
