Guaranteed approximations of arbitrarily quantified reachability problems

no code implementations14 Sep 2023 Eric Goubault, Sylvie Putot

We propose an approach to compute inner and outer-approximations of the sets of values satisfying constraints expressed as arbitrarily quantified formulas.

Taylor-Lagrange Neural Ordinary Differential Equations: Toward Fast Training and Evaluation of Neural ODEs

1 code implementation14 Jan 2022 Franck Djeumou, Cyrus Neary, Eric Goubault, Sylvie Putot, Ufuk Topcu

Neural ordinary differential equations (NODEs) -- parametrizations of differential equations using neural networks -- have shown tremendous promise in learning models of unknown continuous-time dynamical systems from data.

Neural Networks with Physics-Informed Architectures and Constraints for Dynamical Systems Modeling

1 code implementation14 Sep 2021 Franck Djeumou, Cyrus Neary, Eric Goubault, Sylvie Putot, Ufuk Topcu

The physics-informed constraints are enforced via the augmented Lagrangian method during the model's training.

Static analysis of ReLU neural networks with tropical polyhedra

no code implementations30 Jul 2021 Eric Goubault, Sébastien Palumby, Sylvie Putot, Louis Rustenholz, Sriram Sankaranarayanan

This paper studies the problem of range analysis for feedforward neural networks, which is a basic primitive for applications such as robustness of neural networks, compliance to specifications and reachability analysis of neural-network feedback systems.

Neural Network Based Model Predictive Control for an Autonomous Vehicle

no code implementations30 Jul 2021 Maria Luiza Costa Vianna, Eric Goubault, Sylvie Putot

We study learning based controllers as a replacement for model predictive controllers (MPC) for the control of autonomous vehicles.

Tractable higher-order under-approximating AE extensions for non-linear systems

1 code implementation27 Jan 2021 Eric Goubault, Sylvie Putot

We consider the problem of under and over-approximating the image of general vector-valued functions over bounded sets, and apply the proposed solution to the estimation of reachable sets of uncertain non-linear discrete-time dynamical systems.

Reasoning about Uncertainties in Discrete-Time Dynamical Systems using Polynomial Forms.

no code implementations NeurIPS 2020 Sriram Sankaranarayanan, Yi Chou, Eric Goubault, Sylvie Putot

In this paper, we propose polynomial forms to represent distributions of state variables over time for discrete-time stochastic dynamical systems.

On-The-Fly Control of Unknown Systems: From Side Information to Performance Guarantees through Reachability

no code implementations11 Nov 2020 Franck Djeumou, Abraham P. Vinod, Eric Goubault, Sylvie Putot, Ufuk Topcu

Besides, $\texttt{DaTaControl}$ achieves near-optimal control and is suitable for real-time control of such systems.

On-The-Fly Control of Unknown Smooth Systems from Limited Data

no code implementations27 Sep 2020 Franck Djeumou, Abraham P. Vinod, Eric Goubault, Sylvie Putot, Ufuk Topcu

We investigate the problem of data-driven, on-the-fly control of systems with unknown nonlinear dynamics where data from only a single finite-horizon trajectory and possibly side information on the dynamics are available.
