SoftGPT: Learn Goal-oriented Soft Object Manipulation Skills by Generative Pre-trained Heterogeneous Graph Transformer

1 code implementation22 Jun 2023 Junjia Liu, Zhihao LI, WanYu Lin, Sylvain Calinon, Kay Chen Tan, Fei Chen

Soft object manipulation tasks in domestic scenes pose a significant challenge for existing robotic skill learning techniques due to their complex dynamics and variable shape characteristics.

Tensor Train for Global Optimization Problems in Robotics

no code implementations10 Jun 2022 Suhan Shetty, Teguh Lembono, Tobias Loew, Sylvain Calinon

We treat the task parameters as random variables, and for a given task, we generate samples for decision variables from the conditional distribution to initialize the optimization solver.

Ergodic Exploration using Tensor Train: Applications in Insertion Tasks

1 code implementation12 Jan 2021 Suhan Shetty, João Silvério, Sylvain Calinon

In robotics, ergodic control extends the tracking principle by specifying a probability distribution over an area to cover instead of a trajectory to track.

Learning from demonstration using products of experts: applications to manipulation and task prioritization

no code implementations7 Oct 2020 Emmanuel Pignat, João Silvério, Sylvain Calinon

In particular, we show that the proposed approach can be extended to PoE with a nullspace structure (PoENS), where the model is able to recover tasks that are masked by the resolution of higher-level objectives.

Interaction-limited Inverse Reinforcement Learning

no code implementations1 Jul 2020 Martin Troussard, Emmanuel Pignat, Parameswaran Kamalaruban, Sylvain Calinon, Volkan Cevher

This paper proposes an inverse reinforcement learning (IRL) framework to accelerate learning when the learner-teacher \textit{interaction} is \textit{limited} during training.

Bayesian Optimization Meets Riemannian Manifolds in Robot Learning

no code implementations11 Oct 2019 Noémie Jaquier, Leonel Rozo, Sylvain Calinon, Mathias Bürger

Bayesian optimization (BO) recently became popular in robotics to optimize control parameters and parametric policies in direct reinforcement learning due to its data efficiency and gradient-free approach.

Learning from demonstration with model-based Gaussian process

no code implementations11 Oct 2019 Noémie Jaquier, David Ginsbourger, Sylvain Calinon

In learning from demonstrations, it is often desirable to adapt the behavior of the robot as a function of the variability retrieved from human demonstrations and the (un)certainty encoded in different parts of the task.

Gaussians on Riemannian Manifolds: Applications for Robot Learning and Adaptive Control

no code implementations12 Sep 2019 Sylvain Calinon

This article presents an overview of robot learning and adaptive control applications that can benefit from a joint use of Riemannian geometry and probabilistic representations.

Tensor-variate Mixture of Experts for Proportional Myographic Control of a Robotic Hand

1 code implementation28 Feb 2019 Noémie Jaquier, Robert Haschke, Sylvain Calinon

The proposed formulation takes into account the underlying structure of the data and remains efficient when few training data are available.

A survey on policy search algorithms for learning robot controllers in a handful of trials

no code implementations6 Jul 2018 Konstantinos Chatzilygeroudis, Vassilis Vassiliades, Freek Stulp, Sylvain Calinon, Jean-Baptiste Mouret

Most policy search algorithms require thousands of training episodes to find an effective policy, which is often infeasible with a physical robot.

Probabilistic Learning of Torque Controllers from Kinematic and Force Constraints

no code implementations19 Dec 2017 João Silvério, Yanlong Huang, Leonel Rozo, Sylvain Calinon, Darwin G. Caldwell

When learning skills from demonstrations, one is often required to think in advance about the appropriate task representation (usually in either operational or configuration space).
