The Tie in the Ruler
Captions available
The idea
Nearest neighbor stands or falls with its similarity ruler — a coarse ruler produces ties between neighbors with opposite answers, and the method stalls.
In practice
A rainy festival weekend matches one sold-out day and one quiet day equally — two matches each, split verdict.
Where people slip
The patches — more neighbors voting, weighted features — refine the ruler, not the idea.
