Why Machines Learn

Why it’s on the list: Ananthaswamy works through the mathematics under modern machine learning — the perceptron, gradient descent, backpropagation, the kernel trick — at the level of actually following the derivations rather than gesturing at them. The industry answer for AI if you want the mechanism, not the narrative.

Where I saw it: In the reply thread to @WillManidis’s question, “what is the single best book you can read that will explain an entire industry?” (June 2, 2025) — a crowd-sourced list Kyle recovered by hand and saved to his Apple Note “Books To Read”; the full set of replies lives on what is the single best book… (tweet). It was listed there as “Why Machines Learn”.
