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.

Fast Sampling via De-randomization for Discrete Diffusion Models

no code implementations14 Dec 2023 Zixiang Chen, Huizhuo Yuan, YongQian Li, Yiwen Kou, Junkai Zhang, Quanquan Gu

Despite its success in continuous spaces, discrete diffusion models, which apply to domains such as texts and natural languages, remain under-studied and often suffer from slow generation speed.

Optimal Horizon-Free Reward-Free Exploration for Linear Mixture MDPs

no code implementations17 Mar 2023 Junkai Zhang, Weitong Zhang, Quanquan Gu

The sample complexity of our algorithm only has a polylogarithmic dependence on the planning horizon and therefore is "horizon-free".

Rate-Energy Balanced Precoding Design for SWIPT based Two-Way Relay Systems

no code implementations28 Jan 2021 Navneet Garg, Junkai Zhang, Tharmalingam Ratnarajah

It is analyzed that given a non-negative value of CD, the achieved harvested energy for the proposed balanced precoder is higher than that for the perfect interference alignment (IA) precoder.
