I have the data.txt, which calculated by phase space reconstruation method (eLag = 6, eDim = 4) WebKNN algorithm is one of the most used supervised learning method algorithms. KNN algorithm can be used for classification and regression in supervised learning. Substantially, the KNN algorithm assumes that similar points exist in close proximity. K value in the KNN algorithm indicates the number of nearest neighbors.
