Adversarial imitation learning from visual observations using latent information

V Giammarino, J Queeney, IC Paschalidis - arXiv preprint arXiv …, 2023 - arxiv.org
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. The challenges of this …

Visually robust adversarial imitation learning from videos with contrastive learning

V Giammarino, J Queeney, IC Paschalidis - arXiv preprint arXiv …, 2024 - arxiv.org
We propose C-LAIfO, a computationally efficient algorithm designed for imitation learning
from videos in the presence of visual mismatch between agent and expert domains. We …
