Causal Graph ODE: Continuous Treatment Effect Modeling in Multi-agent Dynamical Systems

no code implementations29 Feb 2024 Zijie Huang, Jeehyun Hwang, Junkai Zhang, Jinwoo Baik, Weitong Zhang, Dominik Wodarz, Yizhou Sun, Quanquan Gu, Wei Wang

Real-world multi-agent systems are often dynamic and continuous, where the agents co-evolve and undergo changes in their trajectories and interactions over time.

Generalizing Graph ODE for Learning Complex System Dynamics across Environments

no code implementations10 Jul 2023 Zijie Huang, Yizhou Sun, Wei Wang

In practice, however, we might observe multiple systems that are generated across different environments, which differ in latent exogenous factors such as temperature and gravity.

CF-GODE: Continuous-Time Causal Inference for Multi-Agent Dynamical Systems

no code implementations20 Jun 2023 Song Jiang, Zijie Huang, Xiao Luo, Yizhou Sun

We model a multi-agent dynamical system as a graph and propose CounterFactual GraphODE (CF-GODE), a causal model that estimates continuous-time counterfactual outcomes in the presence of inter-dependencies between units.

Multilingual Knowledge Graph Completion with Self-Supervised Adaptive Graph Alignment

1 code implementation ACL 2022 Zijie Huang, Zheng Li, Haoming Jiang, Tianyu Cao, Hanqing Lu, Bing Yin, Karthik Subbian, Yizhou Sun, Wei Wang

In this paper, we explore multilingual KG completion, which leverages limited seed alignment as a bridge, to embrace the collective knowledge from multiple languages.

Coupled Graph ODE for Learning Interacting System Dynamics

1 code implementation ACM SIGKDD Conference on Knowledge Discovery & Data Mining 2021 Zijie Huang, Yizhou Sun, Wei Wang

On one hand, features of objects change over time, influenced by the linked objects in the interaction graph.

Learning Continuous System Dynamics from Irregularly-Sampled Partial Observations

1 code implementation NeurIPS 2020 Zijie Huang, Yizhou Sun, Wei Wang

In this paper, we propose to learn system dynamics from irregularly-sampled partial observations with underlying graph structure for the first time.
