Latent Collaboration in Multi-Agent Systems

ICML 2026spotlight

Multi-agent systems (MAS) extend large language models (LLMs) from independent single-model reasoning to coordinative system-level intelligence. While existing LLM agents depend on text-based mediation for reasoning and communication, we take a step forward by enabling models to collaborate directly…

Invariant Link Selector for Spatial-Temporal Out-of-Distribution Problem

AISTATS 2025poster

In the era of foundation models, Out-of-Distribution (OOD) problems, i.e., the data discrepancy between the training environments and testing environments, hinder AI generalization. Further, relational data like graphs disobeying the Independent and Identically Distributed (IID) condition makes the…

Learnable Spatial-Temporal Positional Encoding for Link Prediction

ICML 2025poster

Accurate predictions rely on the expressiveness power of graph deep learning frameworks like graph neural networks and graph transformers, where a positional encoding mechanism has become much more indispensable in recent state-of-the-art (SOTA) works to record the canonical position information. Ho…

Temporal Graph Neural Tangent Kernel with Graphon-Guaranteed

NeurIPS 2024poster

_Graph Neural Tangent Kernel_ (GNTK) fuses graph neural networks and graph kernels, simplifies the process of graph representation learning, interprets the training dynamics of graph neural networks, and serves various applications like protein identification, image segmentation, and social network…
