Unbiased Methods for Multi-Goal Reinforcement Learning

no code implementations16 Jun 2021 Léonard Blier, Yann Ollivier

We introduce unbiased deep Q-learning and actor-critic algorithms that can handle such infinitely sparse rewards, and test them in toy environments.

Learning Successor States and Goal-Dependent Values: A Mathematical Viewpoint

no code implementations18 Jan 2021 Léonard Blier, Corentin Tallec, Yann Ollivier

In reinforcement learning, temporal difference-based algorithms can be sample-inefficient: for instance, with sparse rewards, no learning occurs until a reward is observed.

Making Deep Q-learning methods robust to time discretization

1 code implementation28 Jan 2019 Corentin Tallec, Léonard Blier, Yann Ollivier

Despite remarkable successes, Deep Reinforcement Learning (DRL) is not robust to hyperparameterization, implementation details, or small environment changes (Henderson et al. 2017, Zhang et al. 2018).

The Description Length of Deep Learning Models

no code implementations NeurIPS 2018 Léonard Blier, Yann Ollivier

This might explain the relatively poor practical performance of variational methods in deep learning.
