Towards Principled Representation Learning from Videos for Reinforcement Learning

no code implementations20 Mar 2024 Dipendra Misra, Akanksha Saran, Tengyang Xie, Alex Lamb, John Langford

We study two types of settings: one where there is iid noise in the observation, and a more challenging setting where there is also the presence of exogenous noise, which is non-iid noise that is temporally correlated, such as the motion of people or cars in the background.

Interaction-Grounded Learning with Action-inclusive Feedback

no code implementations16 Jun 2022 Tengyang Xie, Akanksha Saran, Dylan J. Foster, Lekan Molu, Ida Momennejad, Nan Jiang, Paul Mineiro, John Langford

Consider the problem setting of Interaction-Grounded Learning (IGL), in which a learner's goal is to optimally interact with the environment with no explicit reward to ground its policies.

A Ranking Game for Imitation Learning

no code implementations7 Feb 2022 Harshit Sikchi, Akanksha Saran, Wonjoon Goo, Scott Niekum

We propose a new framework for imitation learning -- treating imitation as a two-player ranking-based game between a policy and a reward.

Efficiently Guiding Imitation Learning Agents with Human Gaze

no code implementations28 Feb 2020 Akanksha Saran, Ruohan Zhang, Elaine Schaertl Short, Scott Niekum

Based on similarities between the attention of reinforcement learning agents and human gaze, we propose a novel approach for utilizing gaze data in a computationally efficient manner, as part of an auxiliary loss function, which guides a network to have higher activations in image regions where the human's gaze fixated.
