Hearing the shape of an arena with spectral swarm robotics

no code implementations25 Mar 2024 Leo Cazenille, Nicolas Lobato-Dauzier, Alessia Loi, Mika Ito, Olivier Marchal, Nathanael Aubert-Kato, Nicolas Bredeche, Anthony J. Genot

Diffusion over a domain is mathematically encapsulated by the Laplacian, a linear operator that measures the local curvature of a function.

Joint Intrinsic Motivation for Coordinated Exploration in Multi-Agent Deep Reinforcement Learning

1 code implementation6 Feb 2024 Maxime Toquebiau, Nicolas Bredeche, Faïz Benamar, Jae-Yun Jun

We demonstrate the strengths of this approach both in a synthetic environment designed to reveal shortcomings of state-of-the-art MADRL methods, and in simulated robotic tasks.

Meta-control of social learning strategies

1 code implementation18 Jun 2021 Anil Yaman, Nicolas Bredeche, Onur Çaylak, Joel Z. Leibo, Sang Wan Lee

Based on these findings, we hypothesized that meta-control of individual and social learning strategies provides effective and sample-efficient learning in volatile and uncertain environments.

Policy Search with Rare Significant Events: Choosing the Right Partner to Cooperate with

1 code implementation11 Mar 2021 Paul Ecoffet, Nicolas Fontbonne, Jean-Baptiste André, Nicolas Bredeche

This paper focuses on a class of reinforcement learning problems where significant events are rare and limited to a single positive reward per episode.

Exploring Self-Assembling Behaviors in a Swarm of Bio-micro-robots using Surrogate-Assisted MAP-Elites

1 code implementation1 Oct 2019 Leo Cazenille, Nicolas Bredeche, Nathanael Aubert-Kato

Swarms of molecular robots are a promising approach to create specific shapes at the microscopic scale through self-assembly.

Evolutionary optimisation of neural network models for fish collective behaviours in mixed groups of robots and zebrafish

no code implementations9 Aug 2018 Leo Cazenille, Nicolas Bredeche, José Halloy

These models are designed to be implementable as robot controllers to form mixed-groups of fish and robots, using few a priori knowledge of the fish behaviours.

Embodied Evolution in Collective Robotics: A Review

no code implementations26 Sep 2017 Nicolas Bredeche, Evert Haasdijk, Abraham Prieto

This paper provides an overview of evolutionary robotics techniques applied to on-line distributed evolution for robot collectives -- namely, embodied evolution.
