a) A set of data points in a two-dimensional feature space is given by: A (6, 6), B(1, 3), C(6, 5), D(3,2), E(7, 7), F(2, 2,), G(3, 4), H(7, 6), I(2,4) Using geometric interpretation and K-means clustering, Identify the number of clusters that can be formed and compute the centroid of these clusters. [2+2=4M] b) In a binary classification problem of two features with the class labels as (yes, no), the data points are given by: A(-1, 1, yes), B(0, 1, no), C(1, - 1. no). Using 2-Nearest Neighbours, obtain the condition for which the unknown instance point Q(a, b, ?) to be classified as ho [4M]
