Method Detail

computeCliquePotential

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

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
