The Little Book of Generative AI Foundations: An Intuitive Mathematical Primer
The Little Book of Generative AI Foundations: An Intuitive Mathematical Primer
This book provides a concise derivation introduction, explaining the mathematical foundations of modern generative AI. It constructs a coherent understanding path by connecting the ideas of major generative model families (from PCA, variational autoencoders to diffusion models, GANs, etc.). The revised edition adds visual explanations, with 195 pages, suitable for researchers, practitioners, and students interested in mathematics.
Abstract:This book provides a compact, derivation-oriented introduction to the mathematical foundations of modern generative artificial intelligence. Rather than surveying every recent architecture or implementation detail, it develops a coherent route through the ideas connecting major families of generative models, from PCA, probabilistic PCA, variational autoencoders, and diffusion models to normalising flows, autoregressive factorisations, GANs, Wasserstein GANs, and energy-based models. The aim is to make the structure of generative modelling more accessible without removing the mathematical substance needed to understand how these models are derived and related. The book is intended as a foundation-building primer for mathematically curious researchers, practitioners, and students.
