Decision Trees

Finding the questions that split — and knowing when a tree has stopped learning.

The first path in AI & ML Foundations where you build a model rather than sort problems, and it is a tree first because a tree's reasoning is a conversation you can have out loud. One question runs the whole path — which question do you ask first, and how do you know it was right — asked by feel on sixteen animals, by arithmetic on twenty-four films, and then on 1,500 real employees where feel fails. By the end you can build a tree by hand, read every decision it makes, and say when it has stopped learning and started memorising.
