Hello Expert, could you please help me for solving this question (a)(b)(c)(d)?

Thank You Sir

[画像:K-nearest neighbor classification : As shown in the table below, there are seven three-dimensional data points, among which six are labeled and one is unlabeled. Please determine the label of data point C by using the K-nearest neighbor classification method according to the Euclidean distance metric. data points A(7,3,9) B(6,2,1) C(7,10,9) D(8,1,6) E(1,6,7) F(9,7,3) G(9,1,7) label 1 1 2 2 1 1 unknown The definition of Euclidean distance is given below. If you are given two data points, i.e., A = (a1, a2, a3) and B (b1,b2, 63), then Euclidean distance between A and B can be calculated by distance (A, B) = √(a1 − b1)2 + (a2 b2)2 + (a3 -b3)2. = a) Please calculate the Euclidean distances between point and the other points, and fill in the table below. distance(A, G) | distance(B,G) distance(C, G) distance(D, G) | distance(E, G) | distance(F, G) b) Please determine the label of the data point based on the 1-nearest neighbor method (i.e., k = 1). c) Please determine the label of the data point ( based on the 3-nearest neighbors method (i.e., k = 3). d) Please implement the above three questions by coding and paste your codes below. For example, you can paste your Matlab or Python codes below (other programming languages are also welcome).]
