    metricName

    name of default metric

    evaluateFn

    evaluate function:

    • input: dataset consisting of four columns: (label, raw prediction, probability, prediction)
    • output: a single metric value Note: it the user's responsibility to take care of all the error scenarios in evaluateFn
    returns
