Beyond classical regimes in statistical inference and machine learning (06/24 --> 12/24)

The current state of the art in Machine Learning (ML) and Statistical Inference heavily relies on principles which defy traditional statistical thinking, such as high overparameterization in deep learning and non-convex optimization on high-dimensional landscapes using stochastic descent. This brings the necessity of investigating previously unexplored statistical regimes where classical results do not apply to better understand these novel and impactful practices. As a result, innovative theoretical approaches have emerged, notably through interdisciplinary collaborations, among which those based on high-dimensional statistics, random matrix theory and mathematical physics figure prominently. This thematic trimester therefore aims at fostering the interaction of researchers from several communities working in this fast-developing and emerging area, as well as providing young researchers and students with opportunities for acquiring knowledge on these new theoretical approaches of ML and statistical inference which will play a major role in the future of these disciplines.
