Given the prototypes and the corresponding labels below, assign the new sample s = (4,4) by a nearest
neighbor classifier for
(i) k = 1,
(ii) k = 3,
(iii) k = 5.
Prototypes Labels
(1,7) W1
(2,4) W2
(5,4) W1
(1,1) W2
(3,3) W2
(3,6) W1
(6,1) W2
(6,6) W1
Hint: Sketch the prototypes on a 2D space for a clearer picture.
