Learning Synthetic Environments and Reward Networks for Reinforcement Learning

open access: yesCoRR, 2022
We introduce Synthetic Environments (SEs) and Reward Networks (RNs), represented by neural networks, as proxy environment models for training Reinforcement Learning (RL) agents. We show that an agent, after being trained exclusively on the SE, is able to solve the corresponding real environment. While an SE acts as a full proxy to a real environment by

Reinforcement Learning in an Environment Synthetically Augmented with Digital Pheromones [PDF]

open access: yesAdvances in Artificial Intelligence, 2014
Reinforcement learning requires information about states, actions, and outcomes as the basis for learning. For many applications, it can be difficult to construct a representative model of the environment, either due to lack of required information or because of that the model's state space may become too large to allow a solution in a reasonable ...
