Geodesics, Non-linearities and the Archive of Novelty Search

no code implementations6 May 2022 Achkan Salehi, Alexandre Coninx, Stephane Doncieux

An argument that is often encountered in the literature is that the archive prevents exploration from backtracking or cycling, i. e. from revisiting previously encountered areas in the behavior space.

Few-shot Quality-Diversity Optimization

1 code implementation14 Sep 2021 Achkan Salehi, Alexandre Coninx, Stephane Doncieux

Experiments carried in both sparse and dense reward settings using robotic manipulation and navigation benchmarks show that it considerably reduces the number of generations that are required for QD optimization in these environments.

BR-NS: an Archive-less Approach to Novelty Search

1 code implementation8 Apr 2021 Achkan Salehi, Alexandre Coninx, Stephane Doncieux

In this paper, we discuss an alternative approach to novelty estimation, dubbed Behavior Recognition based Novelty Search (BR-NS), which does not require an archive, makes no assumption on the metrics that can be defined in the behavior space and does not rely on nearest neighbours search.

Sparse Reward Exploration via Novelty Search and Emitters

1 code implementation5 Feb 2021 Giuseppe Paolo, Alexandre Coninx, Stephane Doncieux, Alban Laflaquière

Contrary to existing emitters-based approaches, SERENE separates the search space exploration and reward exploitation into two alternating processes.

Novelty Search makes Evolvability Inevitable

2 code implementations13 May 2020 Stephane Doncieux, Giuseppe Paolo, Alban Laflaquière, Alexandre Coninx

Evolvability is thus a natural byproduct of the search in this context.

State Representation Learning from Demonstration

no code implementations15 Sep 2019 Astrid Merckling, Alexandre Coninx, Loic Cressot, Stéphane Doncieux, Nicolas Perrin-Gilbert

Indeed, a compact representation of such a state is beneficial to help robots grasp onto their environment for interacting.

Unsupervised Learning and Exploration of Reachable Outcome Space

1 code implementation12 Sep 2019 Giuseppe Paolo, Alban Laflaquière, Alexandre Coninx, Stephane Doncieux

Results show that TAXONS can find a diverse set of controllers, covering a good part of the ground-truth outcome space, while having no information about such space.

Bootstrapping Robotic Ecological Perception from a Limited Set of Hypotheses Through Interactive Perception

1 code implementation30 Jan 2019 Léni K. Le Goff, Ghanim Mukhtar, Alexandre Coninx, Stéphane Doncieux

A robot with the ability to build and adapt this interpretation process according to its own tasks and capabilities would push away the limits of what robots can achieve in a non controlled environment.

From exploration to control: learning object manipulation skills through novelty search and local adaptation

no code implementations3 Jan 2019 Seungsu Kim, Alexandre Coninx, Stephane Doncieux

The approach has been validated on two different experiments on the Baxter robot: a ball launching and a joystick manipulation tasks.

Quick and energy-efficient Bayesian computing of binocular disparity using stochastic digital signals

no code implementations14 Sep 2016 Alexandre Coninx, Pierre Bessière, Jacques Droulez

Reconstruction of the tridimensional geometry of a visual scene using the binocular disparity information is an important issue in computer vision and mobile robotics, which can be formulated as a Bayesian inference problem.
