Preface

This book is a personal study log for Mathematics for Machine Learning by Marc Peter Deisenroth, A. Aldo Faisal and Cheng Soon Ong. It is not a textbook and it is not a substitute for one: it is a record of working through the book section by section, with the reasoning, the dead ends and the corrections left visible.

Who these notes are for

The notes are written for a reader with an applied-mathematics and professional background — school and additional mathematics, ACCA, and hands-on implementation of Oracle MRP — who wants the formalism of the book connected to practice rather than left floating. Concretely, that means:

• Formal statements are kept, but always attached to an interpretation. A system $Ax=b$ is described both as a matrix equation and as a resource-consumption ledger.
• Operational framings are compared explicitly. When the book’s model differs from how a real planning or optimisation system behaves, the differences are tabulated rather than glossed over.
• Claims are checked. Numerical claims in a note are backed by a runnable script in scripts/, and mistakes are corrected in place with a dated Corrections and additions section instead of being quietly edited away.

How each note is built

Every note follows the same shape, described in detail in docs/note-format.md:

1. The question — the question that motivated the note, reproduced as asked.
2. Screenshots — the page or pages of the book under discussion, so the note is self-contained.
3. Response — the answer that was given, edited only for formatting.
4. Corrections and additions — later fixes, extensions and clarifications, each dated and each stating what it supersedes.
5. References — a link back to the exact section of the book.
