A Model-Based Approach for Improving Reinforcement Learning Efficiency Leveraging Expert Observations

no code implementations29 Feb 2024 Erhan Can Ozcan, Vittorio Giammarino, James Queeney, Ioannis Ch. Paschalidis

This paper investigates how to incorporate expert observations (without explicit information on expert actions) into a deep reinforcement learning setting to improve sample efficiency.

Adversarial Imitation Learning from Visual Observations using Latent Information

1 code implementation29 Sep 2023 Vittorio Giammarino, James Queeney, Ioannis Ch. Paschalidis

We focus on the problem of imitation learning from visual observations, where the learning agent has access to videos of experts as its sole learning source.
