Diverse Policy Optimization for Structured Action Space

1 code implementation23 Feb 2023 Wenhao Li, Baoxiang Wang, Shanchao Yang, Hongyuan Zha

We propose a simple and effective RL method, Diverse Policy Optimization (DPO), to model the policies in structured action space as the energy-based models (EBM) by following the probabilistic RL framework.

Edge Rewiring Goes Neural: Boosting Network Resilience without Rich Features

1 code implementation18 Oct 2021 Shanchao Yang, Kaili Ma, Baoxiang Wang, Tianshu Yu, Hongyuan Zha

In this case, GNNs can barely learn useful information, resulting in prohibitive difficulty in making actions for successively rewiring edges under a reinforcement learning context.

Learning to Generate Time Series Conditioned Graphs with Generative Adversarial Nets

no code implementations3 Mar 2020 Shanchao Yang, Jing Liu, Kai Wu, Mingming Li

Differently, in this paper, we are interested in a novel problem named Time Series Conditioned Graph Generation: given an input multivariate time series, we aim to infer a target relation graph modeling the underlying interrelationships between time series with each node corresponding to each time series.
