Using Generative Adversarial Nets on Atari Games for Feature Extraction in Deep Reinforcement Learning

no code implementations • 6 Apr 2020 • Ayberk Aydın, Elif Surer

In this study, Proximal Policy Optimization (PPO) algorithm is augmented with Generative Adversarial Networks (GANs) to increase the sample efficiency by enforcing the network to learn efficient representations without depending on sparse and delayed rewards as supervision.
