D1.3.4 - nearest neighbour algorithm

The nearest neighbour algorithm.

Use nearest neighbour algorithm to connect the rule to the data and decision in the question.

This matters because nearest neighbour algorithm determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply nearest neighbour algorithm to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: nearest neighbour algorithm is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
