Why Machines Learn: The Elegant Math Behind Modern AI
Anil Ananthaswamy walks through the mathematical ideas that make modern machine learning work, starting with Frank Rosenblatt's perceptron in 1958 and moving through the development of backpropagation, support vector machines, and deep neural networks. He explains the linear algebra, calculus, probability, and optimization that sit underneath each step, while keeping the narrative anchored in the researchers who built the field. The book covers gradient descent, kernel methods, the bias-variance tradeoff, and the surprising effectiveness of overparameterized networks. Ananthaswamy is a science journalist by training, and he treats the math as something to be understood rather than admired from a distance. The result is a book that lets a careful reader see what is actually going on inside systems that are often described only in metaphors.
