Decision tree explained: 15 nodes you can read, 8,524 leaves that memorize
In 42 seconds and narrated: a decision tree with no limit reached AUC 1.000 on the days it learned from and dropped to 0.689 on new days; it asks one variable at a time; unchecked it grew more than 8,500 leaves, and at depth 7, chosen on validation, it did better; the first question barely changes, but the predictions disagree on a third of the days; and for numbers it predicts in steps, flat beyond what it saw. Muted by default: turn the sound on in the controls.
