4-Nearest Neighbor on iris recognition using randomized partitioning.
% 1: Load iris.mat file which contains Iris data and its label
% seperately.
% 2: Randomize the order of data for each iternation so that new sets of
% training and test data are formed.
%
% The training data is of having size of Nxd where N is the number of
% measurements and d is the number of variables of the training data.
%
% Similarly the size of the test data is Mxd where M is the number of
% measurements and d is the number of variables of the test data.
% 3: For each observation in test data, we compute the euclidean distance
% from each obeservation in training data.
% 4: We evalutate 'k' nearest neighbours among them and store it in an
% array.
% 5: We apply the label for which distance is minimum
% 5.1: In case of a tie, we randomly label the class.
% 6: Return the class label.
% 7: Compute confusion matrix.
