Frank Nielsen's short textbook "An Elementary Introduction to Information Geometry" (2020) is now available via ChapterPal, with the author sharing the PDF.
The book is a foundational entry into the differential geometric study of probability, statistics, and machine learning, aimed at graduate students, researchers, and practitioners. It assumes basic linear algebra, multivariable calculus, and classical probability/statistics, and builds up differential geometry from first principles—tangent spaces, metric tensor fields, and affine connections.
