Method Detail

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.

Overrides:

score0 in class DTree.TreeModel

generateModelDescription

protected void generateModelDescription(java.lang.StringBuilder sb)

Specified by:

generateModelDescription in class DTree.TreeModel

toJavaUnifyPreds

protected void toJavaUnifyPreds(SB bodyCtxSB)

Description copied from class: DTree.TreeModel

Generates code which unify preds[1,...NCLASSES]

Overrides:

toJavaUnifyPreds in class DTree.TreeModel
