Class ConfRatio

  • All Implemented Interfaces:
    Confidence
    public class ConfRatio
extends java.lang.Object
implements Confidence
    Weighted true/false ratio confidence measure. Immutable class.

    This measure is available for model versions RFV5 and higher (ibi Patterns 5.4). It takes into account the feature values seen, and weights them based on the influence they have on the final score. It does not take into account the exact combination of feature scores.

    • Constructor Detail

      • ConfRatio

        public ConfRatio()
        Create an instance with default values.

      • ConfRatio

        public ConfRatio​(int minConfCount)
        Create an instance with specific parameter values.
        Parameters:
        minConfCount - The number of training pairs needed to reach full confidence. This is the number of pairs that trained the same score region. Not all pairs train all regions, so this is not a count of the training pairs in the training set. Note this is a count of only the unique pairs. In other words the pairs seen on the first training iteration. Additional iterations do not increase the number of pairs for the purpose of this confidence measure.

    • Method Detail

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object

      • getConfType

        public int getConfType()
        Return the confidence type.
        Specified by:
        getConfType in interface Confidence
        Returns:
        the confidence type for the Weighted Ratio measure.

      • getIntArg

        public int getIntArg​(int idx)
        Return an integer parameter. The first parameter is the minimum confidence count.
        Specified by:
        getIntArg in interface Confidence
        Parameters:
        idx - the integer parameter index, zero based.
        Returns:
        The minimum confidence count for index 0, -1 otherwise.

      • getDblArg

        public double getDblArg​(int idx)
        Return a double parameter. There are no double parameters for this class.
        Specified by:
        getDblArg in interface Confidence
        Parameters:
        idx - the double parameter index, zero based.
        Returns:
        -1.0 for all indexes.
