Bayesian machine learning methods are capable of making predictions with well-quantified uncertainty, and tend to be inherently more robust to noisy data. This makes such methods particularly interesting in engineering and scientific problems that require the use of interpretable machine learning algorithms, but where the available data is sparse and noisy. In this thesis, we explore and demonstrate the usefulness of Bayesian machine learning algorithms in several categories of computational engineering problems. First, we present two Gaussian process-based algorithms for failure prediction of structural components. Second, we show how Bayesian optimization can be applied to efficiently optimize engineering designs that require to be validated by time consuming forward simulations, such as fluid-structure interaction simulations. Third, we demonstrate how Bayesian neural networks can be used for scientific discovery, and present a method to discover unknown partial differential equations from sparse data. Finally, we present a Gaussian process-based reduced-order-model capable of efficiently collecting training data, with application to fluid dynamics simulations.

520 $a Les methodes de machine learning (apprentissage automatique) bayesiennes sont capables de faire des predictions avec une incertitude bien quantifiee et ont tendance a etre intrinsequement plus robustes aux donnees corrompues. Cela rend ces methodes particulierement interessantes pour les problemes scientifiques et d'ingenierie qui necessitent l'utilisation d'algorithmes d'apprentissage automatique interpretables, mais dont les donnees disponibles sont rares et corrompues. Dans cette these, nous explorons et demontrons l'utilite des algorithmes d'apprentissage automatique bayesiens dans plusieurs categories de problemes d'ingenierie numerique. Tout d'abord, nous presentons deux algorithmes bases sur des processus gaussiens pour predire la defaillance de composants structuraux. Deuxiemement, nous montrons comment l'optimisation bayesienne peut etre utilisee pour optimiser efficacement des designs qui necessitent d'etre validees par des simulations couteuses, telles que les simulations d'interaction fluide-structure. Troisiemement, nous demontrons comment des reseaux de neurones bayesiens peuvent etre utilises pour la decouverte scientifique et presentons une methode pour decouvrir des equations aux derivees partielles inconnues a partir de donnees limitees. Enfin, nous presentons un modele d'ordre reduit base sur des processus gaussiens capable de collecter efficacement des donnees d'entrainement, avec une application aux simulations de dynamique des fluides.
