IntFloatPair	chooseSplit(float[][] pnts, IntArrayView inds, int depth, float[] minBounds, float[] maxBounds) Choose the dimension and discriminant on which to split the data.

Method Detail

chooseSplit

IntFloatPair chooseSplit(float[][] pnts,
                         IntArrayView inds,
                         int depth,
                         float[] minBounds,
                         float[] 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).
