GBMModel

        GBMModel.GBMParameters parms,
        GBMModel.GBMOutput output)

Method Detail

schema

public water.api.ModelSchema schema()

Specified by:

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

score0

public float[] score0(water.fvec.Chunk[] chks,
             int row_in_chunk,
             double[] tmp,
             float[] preds)

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 hex.SupervisedModel<GBMModel,GBMModel.GBMParameters,GBMModel.GBMOutput>

score0

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

Overrides:

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