Method Detail

computeCliquePotential

public double computeCliquePotential(int cliqueSize,
                                     int labelIndex,
                                     int[] cliqueFeatures,
                                     double[] featureVal)

Specified by:

computeCliquePotential in interface CliquePotentialFunction

Parameters:

cliqueSize - 1 if node clique, 2 if edge clique, etc

labelIndex - the index of the output class label

cliqueFeatures - an int array containing the feature indices that are active in this clique

featureVal - a double array containing the feature values corresponding to feature indices in cliqueFeatures

Returns:

clique potential value
