Welcome, Idiot

You picked up a book called Practical AI For Idiots. That takes guts. Or maybe you just have bad taste. Either way, you are in the right place.

What This Book Is

This is not a textbook. There are no proofs. No 40-page papers with Greek letters playing hide and seek.

This is a book for people who want to understand AI by building it. From scratch. With their own hands. Like cavemen discovering fire, except the fire is matrix multiplication.

The Three Parts

We are going on a journey:

Part 1: The Tools (Python) You cannot build AI if you cannot talk to a computer. We will learn Python — the language that powers ChatGPT, Tesla, and your Netflix recommendations. It reads like English. You will be fine.

Part 2: The Brain (Machine Learning) We will build 13 different AI algorithms. From drawing a line (Linear Regression) to generating fake human faces (GANs). Each one is a character in a story. You will meet The Sorting Hat, The Blind Hiker, The Goldfish, and The Forger. They all have jobs. They are all idiots in their own way.

Part 3: The Apps (Build Real AI) We stop learning and start building. You will build your own backpropagation engine, your own GPT, your own image classifier, and then put it on the internet for the world to see.

Who This Is For

• You have heard about AI and want to understand it for real
• You tried a textbook and gave up on page 3
• You learn by doing, not by reading about doing
• You are okay with pizza analogies

Who This Is NOT For

• PhDs looking for bleeding-edge research
• People who enjoy reading papers with 47 citations
• Anyone who thinks "softmax" is a type of mattress (okay, maybe you too)

The Rules

1. Every chapter has code. You can read it, but you should run it.
2. Every ML chapter has an interactive demo. Play with the sliders. Break things. That is how you learn.
3. We explain things simply. If something sounds complicated, we failed, not you.

Let's Go

Turn the page. Part 1 starts with Python — the language of gods, written by idiots.
