Class RemoveWorstStdDev

  • All Implemented Interfaces:
    adams.core.Destroyable, adams.core.GlobalInfoSupporter, adams.core.logging.LoggingLevelHandler, adams.core.logging.LoggingSupporter, adams.core.option.OptionHandler, adams.core.QuickInfoSupporter, adams.core.SizeOfHandler, Serializable
    public class RemoveWorstStdDev
extends AbstractNumericClassPostProcessor
    Removes the worst predictions, which are considered outliers that detract from the actual model performance. Uses a standard deviation based approach (threshold: mean + multiplier*stdev). Only works on numeric predictions.
