Exploration by Learning Diverse Skills through Successor State Measures

no code implementations14 Jun 2024 Paul-Antoine Le Tolguenec, Yann Besse, Florent Teichteil-Konigsbuch, Dennis G. Wilson, Emmanuel Rachelson

We propose a formalization of this search for diverse skills, building on a previous definition based on the mutual information between states and skills.

Genetic Drift Regularization: on preventing Actor Injection from breaking Evolution Strategies

no code implementations7 May 2024 Paul Templier, Emmanuel Rachelson, Antoine Cully, Dennis G. Wilson

Here, we highlight the phenomenon of genetic drift where the actor genome and the ES population distribution progressively drift apart, leading to injection having a negative impact on the ES.

Quality with Just Enough Diversity in Evolutionary Policy Search

no code implementations7 May 2024 Paul Templier, Luca Grillotti, Emmanuel Rachelson, Dennis G. Wilson, Antoine Cully

Evolution Strategies (ES) are effective gradient-free optimization methods that can be competitive with gradient-based approaches for policy search.

When, where, and how to add new neurons to ANNs

1 code implementation17 Feb 2022 Kaitlin Maile, Emmanuel Rachelson, Hervé Luga, Dennis G. Wilson

Neurogenesis in ANNs is an understudied and difficult problem, even compared to other forms of structural learning like pruning.

Disentanglement by Cyclic Reconstruction

1 code implementation24 Dec 2021 David Bertoin, Emmanuel Rachelson

This enables the isolation of task-specific information from both domains and a projection into a common representation.

Large Batch Experience Replay

2 code implementations4 Oct 2021 Thibault Lahire, Matthieu Geist, Emmanuel Rachelson

The optimal sampling distribution being intractable, we make several approximations providing good results in practice and introduce, among others, LaBER (Large Batch Experience Replay), an easy-to-code and efficient method for sampling the replay buffer.
