ImitationFlow : learning deep stable stochastic dynamic systems by normalizing flows

Urain, Julen ; Ginesi, Michele ; Tateo, Davide LU orcid and Peters, Jan (2020) 2020 IEEE/RSJ International Conference on Intelligent Robots and Systems, IROS 2020 In IEEE International Conference on Intelligent Robots and Systems p.5231-5237
Abstract

We introduce ImitationFlow, a novel Deep generative model that allows learning complex globally stable, stochastic, nonlinear dynamics. Our approach extends the Normalizing Flows framework to learn stable Stochastic Differential Equations. We prove the Lyapunov stability for a class of Stochastic Differential Equations and we propose a learning algorithm to learn them from a set of demonstrated trajectories. Our model extends the set of stable dynamical systems that can be represented by state-of-the-art approaches, eliminates the Gaussian assumption on the demonstrations, and outperforms the previous algorithms in terms of representation accuracy. We show the effectiveness of our method with both standard datasets and a real robot... (More)
