Calculus Books for Machine Learning

Knowledge of calculus is not required to get results and solve problems in machine learning or deep learning.

However, knowing some calculus will help you in a number of ways, such as in reading mathematical notation in books and papers, and in understanding the terms used to describe fitting models like “gradient,” and in understanding the learning dynamics of models fit via optimization such as neural networks.

Calculus is a challenging topic as taught at a university level, but you don’t need to know all of calculus, just a handful of terms and methods related to numerical function optimization, central to fitting algorithms like neural networks. And the best way to get a handle on calculus is from books.

In this tutorial, you will discover books on calculus for machine learning.

After completing this tutorial, you will know:

• Which books on machine learning provide a gentle introduction to the relevant calculus topics.
• Books that you can use to learn the intuitions, history, and techniques of calculus.
• Textbooks you can use for reference or deeper learning of calculus techniques and their proofs.

Let’s get started.

Tutorial Overview

This tutorial is divided into three parts; they are:

1. Calculus in Machine Learning Books
2. Introductory Calculus Books
3. Calculus Textbooks

Calculus in Machine Learning Books

Start with machine learning books that cover the basics of calculus.

This is perfect if you learned calculus in school (a long time ago) and need a refresh, or if you need a quick crash course in the terms and methods.

Many top machine learning and deep learning textbooks will cover the basics, and it is often enough for most cases, e.g. when you’re focused on getting results with machine learning algorithms.

Also, it helps if you already own a machine learning textbook that covers some calculus as you don’t need to get another book.

Two great textbooks that cover some calculus include:

• Deep Learning, 2016.
• Pattern Recognition and Machine Learning, 2006.

The coverage of calculus in the “Deep Learning” textbook is brief.

Deep Learning

Calculus is introduced in the context of optimization, first in terms of linear regression then more generally for multivariate optimization–seen when fitting neural nets.

This includes topics such as:

• Derivative
• Partial derivative
• Second derivative
• Hessian matrix
• Gradient
• Gradient descent
• Critical points
• Stationary points
• Local maximum
• Global minimum
• Saddle points
• Jacobian matrix

And more.

The book “Pattern Recognition and Machine Learning” provides more in-depth coverage.

Specifically:

• Chapter 10: Approximate Inference
• Appendix D: Calculus of Variations

Pattern Recognition and Machine Learning

Appendix D introduces the topic of “calculus of variations” and Chapter 10 makes use of the technique. The topic is also covered in the deep learning book.

If a typical calculus problem involves finding a value of a variable that optimizes a function, then calculus of variations is about funding a function that optimizes another function. We can see that this is relevant in machine learning and specifically neural networks as the neural network model (circuit) learns arbitrary functions under a loss function.

A common problem in conventional calculus is to find a value of x that maximizes (or minimizes) a function y(x). Similarly, in the calculus of variations we seek a function y(x) that maximizes (or minimizes) a functional F [y]. That is, of all possible functions y(x), we wish to find the particular function for which the functional F [y] is a maximum (or minimum).

— Page 703, Pattern Recognition and Machine Learning, 2006.

The calculus of variations is not required to fit neural nets, but it provides a useful tool to better understand the problem we are solving when fitting a neural net and the types of learning dynamics we may see in practice.

Finally, we are starting to see books dedicated to the mathematical understanding that underlies machine learning.

One example is “Mathematics for Machine Learning.”

Mathematics for Machine Learning

This book covers a lot of the calculus required for machine learning and provides the context showing where it fits in terms of the optimization (training/learning) of models.

Calculus and its Connection to Machine Learning.
Taken from Mathematics for Machine Learning, page 140.

The discussion of calculus is confined to Chapter 5: Vector Calculus, which covers the following topics:

• Section 5.1 Differentiation of Univariate Functions
• Section 5.2 Partial Differentiation and Gradients
• Section 5.3 Gradients of Vector-Valued Functions
• Section 5.4 Gradients of Matrices
• Section 5.5 Useful Identities for Computing Gradients
• Section 5.6 Backpropagation and Automatic Differentiation
• Section 5.7 Higher-Order Derivatives
• Section 5.8 Linearization and Multivariate Taylor Series

This book is an excellent starting point to fill out or refresh your knowledge of calculus for machine learning.

Introductory Calculus Books

Knowing the names of terms is one thing, but what if you want to know some of the methods more generally?

For that, I would recommend a solid beginner book, such as:

• The Hitchhiker’s Guide to Calculus, 2019.
• Calculus For Dummies, 2016.

These are not textbooks; instead, they assume little or no background (e.g. pre-calculus) and will step you through the intuitions and the techniques and their application to simple exercises.

Intuition is key! We’re not doing math degrees; we’re solving machine learning problems.

A textbook will teach you the method and the proof but rarely tell you what problem the method was designed to solve in the first place and a little history. I think background is critical.

Calculus For Dummies

I own both books. I like “Calculus For Dummies” and would recommend it, if you can get past the name and style.

There are many who say that calculus is one of the crowning achievements in all of intellectual history. As such, it’s worth the effort. Read this jargon-free book, get a handle on calculus, and join the happy few who can proudly say, “Calculus? Oh, sure, I know calculus. It’s no big deal.”

The Hitchhiker’s Guide to Calculus

I find “The Hitchhiker’s Guide to Calculus” good, but terse. It’s straight to the point of each method.

The best thing about this book is that it is focused on making you do calculations. Learn by calculating. This is how I learn.

… Calculus requires understanding a whole new set of ideas, ones which are very interesting and quite beautiful, but admittedly also a bit hard to grasp. Yet, with all the new ideas that it entails, Calculus is a method of calculation, so in your Calculus course you are going to be doing calculations, reams of calculations, oodles of calculations, a seeming endless number of calculations!

— Pages 1-2, The Hitchhiker’s Guide to Calculus, 2019.

Another book I strongly recommend is a popular science book:

• Infinite Powers: How Calculus Reveals the Secrets of the Universe, 2020.

Infinite Powers

This book will get you excited about calculus.

It covers the history and will ground you in why the tools of calculus were invented and why they are so powerful.

Without calculus, we wouldn’t have cell phones, computers, or microwave ovens. We wouldn’t have radio. Or television. Or ultrasound for expectant mothers, or GPS for lost travelers. We wouldn’t have split the atom, unraveled the human genome, or put astronauts on the moon. We might not even have the Declaration of Independence.

— Page vii, Infinite Powers, 2020.

History is important. You need someone to lay out the hard problems that geometry and algebra could not solve, the hacks that were tried, and the new methods that were invented that work really well.

Calculus began as an outgrowth of geometry. Back around 250 bce in ancient Greece, it was a hot little mathematical startup devoted to the mystery of curves.

— Page 3, Infinite Powers, 2020.

It hammers home that calculus is not magic and spells, but tools for solving problems. And that it’s all learnable, if you want.

Calculus Textbooks

Maybe you want to go deeper.

You want to see and work through proofs for each method, work through practice exercises at an undergraduate level, go deep.

This is not required to be effective at machine learning, but sometimes we want to go all in. I understand. In that case, I recommend a textbook, such as a textbook used for undergraduate courses.

It can also be a good idea to have a textbook on hand to dip into the details of specific terms and methods on demand when using high-level/simpler material. E.g. really digging into the Hessian matrix.

There are a huge number of textbooks on calculus and seemingly new editions every few years.

Nevertheless, some of the top textbooks used at the university level include the following:

• Calculus, 3rd Edition, 2017. (Gilbert Strang)
• Calculus, 8th edition, 2015. (James Stewart)
• Calculus, 4th edition, 2008. (Michael Spivak)
• Calculus, 11th edition, 2017. (Ron Larson, Bruce Edwards)
• Thomas’ Calculus, 14th edition, 2017. (Joel Hass, Christopher Heil, Maurice Weir)

I like Stewart, but they’re all pretty much the same. All are hard work.

Calculus

You will be expected to do a ton of worked examples. There’s no way around it.

Perhaps skim a few and pick one that feels like a good fit for your learning style.
