La XXVII° édition des journées FAC a eu lieu les 14 et 15 octobre 2021 à l’ENAC (bâtiment Bréguet, amphithéâtre Bellonte, 7, avenue Édouard-Belin, Toulouse).

Ces journées sont organisées par le groupe IFSE du RTRA STAE avec un soutien spécial de l’INSA Toulouse, de l’ISAE et de l’ENAC.

La participation est gratuite. Pensez à vous inscrire.

Programme des journées

Jeudi 14 octobre

  • 09h00 : accueil présentation des journées

  • 09h30-10h30 : Invited talk.

    Joao Marques-Silva (IRIT, Toulouse): Logic-Based Explainable AI.

The forecast applications of machine learning (ML) in high-risk and safety-critical applications hinge on systems that are robust in their operation and that can be trusted. This talk overviews recent efforts on applying logic-enabled automated reasoning tools in explaining non-interpretable (black-box) ML models. Concretely, the talk details the computation of rigorous explanations of black-box models, and how these serve for assessing the quality of widely used heuristic explanation approaches. The talk also overviews properties relating different kinds of rigorous explanations. Finally, the talk briefly overviews ongoing work on mapping tractable explainability.

Vendredi 15 octobre

  • 09h30-10h30 : Invited Talk

    Behçet Açikmeşe (Univ. Washington, Seattle): Optimization Based Control – An Aerospace Perspective.

Many future aerospace engineering applications will require dramatic increases in our existing autonomous control capabilities. These include robotic sample return missions to planets, comets, and asteroids, formation flying spacecraft, swarms of autonomous spacecraft, unmanned aerial, ground, and underwater vehicles, and autonomous commercial robotic applications. A key control challenge for many autonomous systems is to achieve the performance goals safely with minimal resource use in the presence of mission constraints and uncertainties. In principle these problems can be formulated and solved as optimal control problems. The challenge is solving them reliably in real-time, while assuring: i) full utilization of the performance envelope for the autonomous system; ii) systematic verification of the control algorithms. Our approach to solving these challenging control problems is optimization-based control where we formulate these control problems as optimization problems and then to exploit convex optimization theory and algorithms for their robust and numerically efficient solutions.
