WebNearest neighbors are defined by distance, but what distance metrics do you use? Do you transform the data? If yes, then how? Do you see how the complexity of the problem keeps going up by asking simple questions. You model is the last step of the study, the data that underlies it is far more important 7 level 1 Nater5000 · 2y WebDescription. example. Idx = knnsearch (X,Y) finds the nearest neighbor in X for each query point in Y and returns the indices of the nearest neighbors in Idx, a column vector. Idx has the same number of rows as Y. Idx = knnsearch (X,Y,Name,Value) returns Idx with additional options specified using one or more name-value pair arguments.
