Method Detail

sdev

public double[] sdev()

eigVec

public double[][] eigVec()

score0

protected float[] score0(double[] data,
                         float[] preds)

Description copied from class: Model

Subclasses implement the scoring logic. The data is pre-loaded into a re-used temp array, in the order the model expects. The predictions are loaded into the re-used temp array, which is also returned.

Specified by:

score0 in class Model

delete

public void delete()

Description copied from class: Model

Called when deleting this model, to cleanup any internal keys

Overrides:

delete in class Model

toString

public java.lang.String toString()

Overrides:
