Mitigating Covariate Shift in Behavioral Cloning via Robust Stationary Distribution Correction

NeurIPS 2024poster

We consider offline imitation learning (IL), which aims to train an agent to imitate from the dataset of expert demonstrations without online interaction with the environment. Behavioral Cloning (BC) has been a simple yet effective approach to offline IL, but it is also well-known to be vulnerable t…

Information-Theoretic State Space Model for Multi-View Reinforcement Learning

ICML 2023oral

Multi-View Reinforcement Learning (MVRL) seeks to find an optimal control for an agent given multi-view observations from various sources. Despite recent advances in multi-view learning that aim to extract the latent representation from multi-view data, it is not straightforward to apply them to con…

Regularized Behavior Cloning for Blocking the Leakage of Past Action Information

NeurIPS 2023spotlight

For partially observable environments, imitation learning with observation histories (ILOH) assumes that control-relevant information is sufficiently captured in the observation histories for imitating the expert actions. In the offline setting wherethe agent is required to learn to imitate without…

DemoDICE: Offline Imitation Learning with Supplementary Imperfect Demonstrations

ICLR 2022poster

We consider offline imitation learning (IL), which aims to mimic the expert's behavior from its demonstration without further interaction with the environment. One of the main challenges in offline IL is to deal with the narrow support of the data distribution exhibited by the expert demonstrations…

Multi-View Representation Learning via Total Correlation Objective

NeurIPS 2021poster

Multi-View Representation Learning (MVRL) aims to discover a shared representation of observations from different views with the complex underlying correlation. In this paper, we propose a variational approach which casts MVRL as maximizing the amount of total correlation reduced by the representati…

Variational Interaction Information Maximization for Cross-domain Disentanglement

NeurIPS 2020poster

Cross-domain disentanglement is the problem of learning representations partitioned into domain-invariant and domain-specific representations, which is a key to successful domain transfer or measuring semantic distance between two domains. Grounded in information theory, we cast the simultaneous lea…
