Field Detail

mtries

public int mtries

Number of variables randomly sampled as candidates at each split. If set to -1, defaults to sqrt{p} for classification and p/3 for regression (where p is the # of predictors

sampleRate

@SerializedName(value="sample_rate")
public double sampleRate

Row sample rate per tree (from 0.0 to 1.0)

treatmentColumn

@SerializedName(value="treatment_column")
public java.lang.String treatmentColumn

Define the column which will be used for computing uplift gain to select best split for a tree. The column has to divide the dataset into treatment (value 1) and control (value 0) groups.

upliftMetric

@SerializedName(value="uplift_metric")
public TreeupliftUpliftDRFModelUpliftDRFParametersUpliftMetricType upliftMetric

Divergence metric used to find best split when building an uplift tree.

auucType

@SerializedName(value="auuc_type")
public AUUCType auucType

Metric used to calculate Area Under Uplift Curve.

auucNbins

@SerializedName(value="auuc_nbins")
public int auucNbins

Number of bins to calculate Area Under Uplift Curve.
