Investigation of Independent Reinforcement Learning Algorithms in Multi-Agent Environments

no code implementations1 Nov 2021 Ken Ming Lee, Sriram Ganapathi Subramanian, Mark Crowley

We show that in fully-observable environments, independent algorithms can perform on par with multi-agent algorithms in cooperative and competitive settings.

Multi-Agent Advisor Q-Learning

1 code implementation26 Oct 2021 Sriram Ganapathi Subramanian, Matthew E. Taylor, Kate Larson, Mark Crowley

In the last decade, there have been significant advances in multi-agent reinforcement learning (MARL) but there are still numerous challenges, such as high sample complexity and slow convergence to stable policies, that need to be overcome before wide-spread deployment is possible.

The Effect of Q-function Reuse on the Total Regret of Tabular, Model-Free, Reinforcement Learning

no code implementations7 Mar 2021 Volodymyr Tkachuk, Sriram Ganapathi Subramanian, Matthew E. Taylor

We aim to bridge the gap between theoretical and empirical work in $Q$-function reuse by providing some theoretical insights on the effectiveness of $Q$-function reuse when applied to the $Q$-learning with UCB-Hoeffding algorithm.

Partially Observable Mean Field Reinforcement Learning

1 code implementation31 Dec 2020 Sriram Ganapathi Subramanian, Matthew E. Taylor, Mark Crowley, Pascal Poupart

Traditional multi-agent reinforcement learning algorithms are not scalable to environments with more than a few agents, since these algorithms are exponential in the number of agents.

Maximum Reward Formulation In Reinforcement Learning

1 code implementation8 Oct 2020 Sai Krishna Gottipati, Yashaswi Pathak, Rohan Nuttall, Sahir, Raviteja Chunduru, Ahmed Touati, Sriram Ganapathi Subramanian, Matthew E. Taylor, Sarath Chandar

Reinforcement learning (RL) algorithms typically deal with maximizing the expected cumulative return (discounted or undiscounted, finite or infinite horizon).

A review of machine learning applications in wildfire science and management

no code implementations2 Mar 2020 Piyush Jain, Sean C P Coogan, Sriram Ganapathi Subramanian, Mark Crowley, Steve Taylor, Mike D Flannigan

Artificial intelligence has been applied in wildfire science and management since the 1990s, with early applications including neural networks and expert systems.

Multi Type Mean Field Reinforcement Learning

1 code implementation6 Feb 2020 Sriram Ganapathi Subramanian, Pascal Poupart, Matthew E. Taylor, Nidhi Hegde

We consider two different kinds of mean field environments: a) Games where agents belong to predefined types that are known a priori and b) Games where the type of each agent is unknown and therefore must be learned based on observations.
