Singular Learning Theory (SLT), pioneered by Sumio Watanabe, acknowledges the presence of singularities in statistical models. provides a foundation grounded in Algebraic Geometry to work with singularities. clarifies foundational results in probability and statistics when regularity assumptions are violated. studies how properties of model singularities and other algebro-geometric properties affect properties of statistical models.

Three volume history of Mathematics recommended by Timothy Gowers at the end of his Mathematics: A Very Short Introduction

This book is an invitation to discover advanced topics in category theory through concrete, real-world examples. It aims to give a tour: a gentle, quick introduction to guide later exploration. The tour takes place over seven sketches, each pairing an evocative application, such as databases, electric circuits, or dynamical systems, with the exploration of a categorical structure, such as adjoint functors, enriched categories, or toposes. No prior knowledge of category theory is assumed.
