Bengio, examiner  \n2025  \nAbstract  \nAs machine learning systems move from statistical tools to core societal infrastructure, their trustworthiness has become a primary scientific challenge. This requires a foundational shift from maximizing accuracy to providing formal guarantees on three critical properties: privacy, to protect the confidentiality of user data; robustness, to ensure integrity against malicious participants and data; and unlearning, to provide meaningful user control. This dissertation analyzes these pillars through a unified lens of quantifiable costs—in model performance (utility), system requirements (assumptions), and computation (resources) . Our analysis uncovers deep interactions between these trust guarantees, revealing them to be both antagonistic, as when privacy mechanisms hinder robustness, and synergistic, as when robust training provides a foundation for efficient unlearning. It also highlights fundamental separations, showing that unlearning, while related to privacy, is a distinct goal that can be achieved at a significantly lower utility cost. This work therefore provides a foundational map of these interactions, contributing towards a principled science of trustworthy machine learning.  \nKeywords: machine learning, differential privacy, robust statistics, optimization, right-to-beforgotten, federated learning, distributed learning, collaborative learning  \nRésumé  \nÀ mesure que les systèmes d’apprentissage automatique passent du statut d’outils statistiques à celui d’infrastructures fondamentales de la société, leur fiabilité est devenue un défi scientifique majeur. Ceci exige un changement de paradigme, passant de la maximisation de la précision à l’obtention de garanties formelles sur trois propriétés critiques : la confidentialité, pour protéger la confidentialité des données des utilisateurs ; la robustesse, pour assurer l’intégrité contre les participants et les données malveillantes ; et le désapprentissage, pour offrir uncontrôle significatif aux utilisateurs. Cette thèse analyse ces piliers à travers le prisme unifié decoûts quantifiables, en performance du modèle (utilité), en exigences du système (hypothèses), et en calcul (ressources) . Notre analyse révèle de profondes interactions entre ces garanties de confiance, montrant qu’elles peuvent être à la fois antagonistes, comme lorsque les mécanismes de confidentialité entravent la robustesse, et synergiques, comme lorsque l’entraînement robuste sert de fondation à un désapprentissage efficace. Elle met également en évidence des séparations fondamentales, montrant que le désapprentissage, bien que lié à la confidentialité, est un objectif distinct qui peut être atteint à un coût nettement inférieur. Ce travail fournit ainsi une cartographie fondatrice de ces interactions, contribuant à une science rigoureuse del’apprentissage automatique fiable.  \nMots clefs : apprentissage automatique, confidentialité différentielle, statistiques robustes, optimisation, droit à l’oubli, apprentissage fédéré, apprentissage distribué, apprentissage collaboratif  \nAcknowledgements  \nI am grateful to all people and institutions who have contributed to or supported this thesis.
