Method Detail

chooseSplit

IntDoublePair chooseSplit(double[][] pnts,
                        IntArrayView inds,
                        int depth,
                        double[] minBounds,
                        double[] maxBounds)

Choose the dimension and discriminant on which to split the data.

Parameters:

pnts - the raw data

inds - the indices of the data under consideration

depth - the depth of the current data in the tree

minBounds - the minimum bounds

maxBounds - the maximum bounds

Returns:

the dimension and discriminant, or null iff this is a leaf (containing all the points in inds).
