public class VisualizePairwiseGainMatrix
extends AbstractApplication

Class to load an outlier detection summary file, as produced by ComputeKNNOutlierScores, and compute a matrix with the pairwise gains. It will have one column / row obtained for each combination. The gain is always computed in relation to the better of the two input methods. Green colors indicate the result has improved, red indicate it became worse. Reference:
