Regularizing Adversarial Imitation Learning Using Causal Invariance

no code implementations17 Aug 2023 Ivan Ovinnikov, Joachim M. Buhmann

Imitation learning methods are used to infer a policy in a Markov decision process from a dataset of expert demonstrations by minimizing a divergence measure between the empirical state occupancy measures of the expert and the policy.

Learning Invariant Reward Functions through Trajectory Interventions

no code implementations29 Sep 2021 Ivan Ovinnikov, Eugene Bykovets, Joachim M. Buhmann

Inverse reinforcement learning methods aim to retrieve the reward function of a Markov decision process based on a dataset of expert demonstrations.

Inverse Reinforcement Learning via Matching of Optimality Profiles

no code implementations18 Nov 2020 Luis Haug, Ivan Ovinnikov, Eugene Bykovets

Given an optimality profile and a small amount of additional supervision, our algorithm fits a reward function, modeled as a neural network, by essentially minimizing the Wasserstein distance between the corresponding induced distribution and the optimality profile.
