% implements Classify, return the predicted class for each row (we'll call each row x) in data % by computing the posterior probability that x is in class 1 vs. class 2 then % these posterior probabilities are compared using the log odds. function [predictions] = Classify(data, m1, m2, S1, S2, pc1, pc2) d = 8; % TODO: calculate P(x|C) * P(C) for both classes pxC1 = exp(-1/2*(data-m1)./S1*(data-m1)') / (power(2*pi,d/2) * sqrt(det(S1))); pxC2 = exp(-1/2*(data-m2)*(S2\(data-m2).')); g1 = pxC1 * pc1; g2 = pxC2 * pc2; % TODO: calculate log odds, if > 0 then data(i) belongs to class c1, else, c2 for i = 1:length(data) data(i) end % TODO: get predictions from log odds calculation end % Function end
