Question-14

KNN

You have the following \(5\) data points: \((0, 0), (2, 2), (4, 4), (5, 5)\) and \((10, 10)\), with corresponding labels \(A, A, B, B\) and \(A\). If you use KNN with \(k = 3\), what will be the predicted label for a test point at \((3,3)\)

A
B
Cannot be determined
A and B equally

Hint

Answer

A
B
Cannot be determined
A and B equally

Solution

All the five points lie on the line \(y = x\). The distance computation therefore becomes quite trivial.
