The Decision Tree
Captions available
The idea
A decision tree predicts by asking one question at a time, branching on the answer — learned by choosing, at each point, the question that best sorts the pile.
In practice
Audition each feature: split the pile, guess each side's majority, count the misses; the fewest misses wins the root.
Where people slip
The tree commits to a compact, auditable theory — readable and arguable, unlike the stored-neighbors method.
