MDPGT: Momentum-based Decentralized Policy Gradient Tracking

1 code implementation6 Dec 2021 Zhanhong Jiang, Xian Yeow Lee, Sin Yong Tan, Kai Liang Tan, Aditya Balu, Young M. Lee, Chinmay Hegde, Soumik Sarkar

We propose a novel policy gradient method for multi-agent reinforcement learning, which leverages two different variance-reduction techniques and does not require large batches over iterations.

Query-based Targeted Action-Space Adversarial Policies on Deep Reinforcement Learning Agents

1 code implementation13 Nov 2020 Xian Yeow Lee, Yasaman Esfandiari, Kai Liang Tan, Soumik Sarkar

As the complexity of CPS evolved, the focus has shifted from traditional control methods to deep reinforcement learning-based (DRL) methods for control of these systems.

Deep Reinforcement Learning for Adaptive Traffic Signal Control

no code implementations14 Nov 2019 Kai Liang Tan, Subhadipto Poddar, Anuj Sharma, Soumik Sarkar

In this paper, we propose a DRL-based adaptive traffic signal control framework that explicitly considers realistic traffic scenarios, sensors, and physical constraints.

Spatiotemporally Constrained Action Space Attacks on Deep Reinforcement Learning Agents

1 code implementation5 Sep 2019 Xian Yeow Lee, Sambit Ghadai, Kai Liang Tan, Chinmay Hegde, Soumik Sarkar

In this work, we first frame the problem as an optimization problem of minimizing the cumulative reward of an RL agent with decoupled constraints as the budget of attack.
