GBMModel

public GBMModel(water.Key selfKey,
        GBMModel.GBMParameters parms,
        GBMModel.GBMOutput output)

Method Detail

score0

protected double[] score0(double[] data,
              double[] preds,
              double weight,
              double offset)

Bulk scoring API for one row. Chunks are all compatible with the model, and expect the last Chunks are for the final distribution and prediction. Default method is to just load the data into the tmp array, then call subclass scoring logic.

Overrides:

score0 in class SharedTreeModel<GBMModel,GBMModel.GBMParameters,GBMModel.GBMOutput>

toJavaUnifyPreds

protected void toJavaUnifyPreds(water.util.SB body,
                    water.util.SB file)

Specified by:

toJavaUnifyPreds in class SharedTreeModel<GBMModel,GBMModel.GBMParameters,GBMModel.GBMOutput>
