Seminar logo

Les séminaires du GEODES visent à rassembler les membres du groupe de manière périodique dans un cadre semi-formel pour échanger autour d'une thématique.
Les séminaires donnent aux étudiants l'opportunité de partager leur avancement et trouvaille et présenter un sujet lié aux thèmes de recherche du groupe. Ils ont ainsi l'occasion de pratiquer leur présentation à venir et récolter de la rétroaction.

    Surrogate Models for Complex System Emulation
    • Paul Saves – Postdoctoral researcher at the University of Toulouse
    Complex systems, whether in engineering design or socio-environmental modeling, often rely on expensive and opaque simulations, typically treated as "black boxes." This presentation focuses on the Surrogate Modeling Toolbox (SMT), an open-source Python package designed to train lightweight statistical emulators to bypass these high computational costs. We will detail how SMT handles heterogeneous design spaces, including mixed variables (continuous and categorical) and conditional hierarchical structures. We will then demonstrate how these surrogate models serve as a stepping stone toward Explainable AI (XAI), active learning, and optimization. Finally, we will illustrate these methods with concrete optimization cases and discuss their application to Agent-Based Models (ABM) for policy analysis and the simulation of socio-technical systems.
