While the native action space is completely intractable for simple DQN agents, our architecture can be used to establish an effective way to interact with different tasks, significantly improving the performance of the same DQN agent over different levels of abstraction.

What can I do here? A Theory of Affordances in Reinforcement Learning

1 code implementation • ICML 2020 • Khimya Khetarpal, Zafarali Ahmed, Gheorghe Comanici, David Abel, Doina Precup

Gibson (1977) coined the term "affordances" to describe the fact that certain states enable an agent to do certain actions, in the context of embodied agents.

Basis refinement strategies for linear value function approximation in MDPs

no code implementations • NeurIPS 2015 • Gheorghe Comanici, Doina Precup, Prakash Panangaden

We provide a theoretical framework for analyzing basis function construction for linear value function approximation in Markov Decision Processes (MDPs).
