Constructor Detail

IsolationForestModel

public IsolationForestModel(water.Key<IsolationForestModel> selfKey,
                            IsolationForestModel.IsolationForestParameters parms,
                            IsolationForestModel.IsolationForestOutput output)

Method Detail

makeMetricBuilder

public hex.ModelMetrics.MetricBuilder makeMetricBuilder(java.lang.String[] domain)

Overrides:

makeMetricBuilder in class SharedTreeModel<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>

makeScoringNames

protected java.lang.String[] makeScoringNames()

Overrides:

makeScoringNames in class hex.Model<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>

makeScoringDomains

protected java.lang.String[][] makeScoringDomains(water.fvec.Frame adaptFrm,
                                                  boolean computeMetrics,
                                                  java.lang.String[] names)

Overrides:

makeScoringDomains in class hex.Model<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>

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<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>

toJavaUnifyPreds

protected void toJavaUnifyPreds(water.util.SBPrintStream body)

Specified by:

toJavaUnifyPreds in class SharedTreeModel<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>

getMojo

public IsolationForestMojoWriter getMojo()

Overrides:

getMojo in class hex.Model<IsolationForestModel,IsolationForestModel.IsolationForestParameters,IsolationForestModel.IsolationForestOutput>
