make

public static ModelMetricsBinomial make(Vec targetClassProbs,
                                        Vec actualLabels)

Build a Binomial ModelMetrics object from target-class probabilities, from actual labels, and a given domain for both labels (and domain[1] is the target class)

Parameters:

targetClassProbs - A Vec containing target class probabilities

actualLabels - A Vec containing the actual labels (can be for fewer labels than what's in domain, since the predictions can be for a small subset of the data)

Returns:

ModelMetrics object

make

public static ModelMetricsBinomial make(Vec targetClassProbs,
                                        Vec actualLabels,
                                        java.lang.String[] domain)

Build a Binomial ModelMetrics object from target-class probabilities, from actual labels, and a given domain for both labels (and domain[1] is the target class)

Parameters:

targetClassProbs - A Vec containing target class probabilities

actualLabels - A Vec containing the actual labels (can be for fewer labels than what's in domain, since the predictions can be for a small subset of the data)

domain - The two class labels (domain[0] is the non-target class, domain[1] is the target class, for which probabilities are given)

Returns:

ModelMetrics object
