Class AddMetric

  • All Implemented Interfaces:
    Serializable, Cloneable, Comparable, org.jgap.gp.IMutateable, org.jgap.util.ICloneable
    public class AddMetric
extends org.jgap.gp.CommandGene
implements org.jgap.gp.IMutateable, org.jgap.util.ICloneable
    Class to implement the ADD command for evolution of metric expressions. A ADD Command combines Similarity Measures with coefficients. E.g. "ADD(0.5*trigram(x.title,y.title)|0.9, 0.5*cosine(x.authors,y.authors)|0.7)". So LIMES recalculates the thresholds: threshold1 = (threshold - coef2) / coef1;

          throws org.jgap.InvalidConfigurationException
        Constructor to manually set return type.
        Parameters:
        config - A GPConfiguration
        a_returnType - Class this CommandGene returns on executing.
        Throws:

      • removeThresholdFromMeasure

        public static String removeThresholdFromMeasure​(String measure)
        ADD metrics only have coefficients no local thresholds. So this function removes them.
        Parameters:
        measure - , e.g. trigrams(s.x,t.y)|0.8
        Returns:
        shortened measure, e.g. trigrams(s.x,t.y)

                             int a_chromNum)
        We're expecting 2 pairs of aSimilarityCommand and a coefficient.
        Overrides:
        getChildType in class org.jgap.gp.CommandGene
        Parameters:
        a_ind - A GPProgram
