Constructor Detail

GBMModel

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

Method Detail

score0

protected double[] score0(double[] data,
              double[] preds,
              double offset,
              int ntrees)

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.SBPrintStream body)

Specified by:

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

getMojo

public GbmMojoWriter getMojo()

Overrides:

getMojo in class hex.Model<GBMModel,GBMModel.GBMParameters,GBMModel.GBMOutput>
