Constructor Detail

MinkowskiD_row

public MinkowskiD_row(int power)

Minkowski metrics are a family of distance measurements which are generalized from the Euclidean distance formula. Two values of power have easily interpretable meanings: At power=2, you get the typical Euclidean distance and at power=1 yields the city-block metric, so named because it gives the distance you'd have to travel to get between two points if you were walking on a grid of city streets (no real diagonals).
Default is power=2.

Parameters:

power - the Minkowski parameter

Method Detail

analyzeMatrix

public double[][] analyzeMatrix(float[][] data_matrix)

Specified by:

analyzeMatrix in class SimilarityMeasure

Parameters:

data_matrix - an array of float arrays denoting the rows in the matrix that are to be compared for similarity.

Returns:

an array of double arrays containing the similarities between all rows
