Non-Stationary Policy Learning for Multi-Timescale Multi-Agent Reinforcement Learning

no code implementations17 Jul 2023 Patrick Emami, Xiangyu Zhang, David Biagioni, Ahmed S. Zamzam

In detail, we theoretically demonstrate that the effects of non-stationarity introduced by multiple timescales can be learned by a periodic multi-agent policy.

Plug & Play Directed Evolution of Proteins with Gradient-based Discrete MCMC

1 code implementation20 Dec 2022 Patrick Emami, Aidan Perreault, Jeffrey Law, David Biagioni, Peter C. St. John

We introduce a sampling framework for evolving proteins in silico that supports mixing and matching a variety of unsupervised models, such as protein language models, and supervised models that predict protein function from sequence.

From Model-Based to Model-Free: Learning Building Control for Demand Response

1 code implementation18 Oct 2022 David Biagioni, Xiangyu Zhang, Christiane Adcock, Michael Sinner, Peter Graf, Jennifer King

We demonstrate, in this context, that hybrid methods offer many benefits over both purely model-free and model-based methods as long as certain requirements are met.

PowerGridworld: A Framework for Multi-Agent Reinforcement Learning in Power Systems

1 code implementation10 Nov 2021 David Biagioni, Xiangyu Zhang, Dylan Wald, Deepthi Vaidhynathan, Rohit Chintala, Jennifer King, Ahmed S. Zamzam

We present the PowerGridworld software package to provide users with a lightweight, modular, and customizable framework for creating power-systems-focused, multi-agent Gym environments that readily integrate with existing training frameworks for reinforcement learning (RL).

A Modular and Transferable Reinforcement Learning Framework for the Fleet Rebalancing Problem

no code implementations27 May 2021 Erotokritos Skordilis, Yi Hou, Charles Tripp, Matthew Moniot, Peter Graf, David Biagioni

To help bridge the gap between novel and existing methods, we propose a modular framework for fleet rebalancing based on model-free reinforcement learning (RL) that can leverage an existing dispatch method to minimize system cost.

Learning-Accelerated ADMM for Distributed Optimal Power Flow

no code implementations8 Nov 2019 David Biagioni, Peter Graf, Xiangyu Zhang, Ahmed Zamzam, Kyri Baker, Jennifer King

We propose a novel data-driven method to accelerate the convergence of Alternating Direction Method of Multipliers (ADMM) for solving distributed DC optimal power flow (DC-OPF) where lines are shared between independent network partitions.
