KNNDD K-Nearest neighbour data description method. W = KNNDD(A,FRACREJ,K,METHOD) Calculates the K-Nearest neighbour data description on dataset A. Three methods are defined to compute a distance to the dataset using the k-nearest neighbours:
METHOD uses the 'kappa' distance to the k-th nearest neighbor 'delta' distance to the average of the k-nn's 'gamma' average distance to the k-nn's
When no K is defined, it will be optimized using knn_optk, when it is smaller than 0, sqrt(n) will be used.
