Interface SimilarityMatrix

All Superinterfaces:

CategoryMatrix

public interface SimilarityMatrix

extends CategoryMatrix

A SimilarityMatrix specifies the similarity values between two values of an attribute. The value at entry (j, k) is the similarity value for attribute values j and k. A similarity matrix is symmetric, i.e., the value at (j, k) is the same as the value at (k, j).

If nothing is set, getValue returns 1 in the diagonal and 0 in the off-diagonal.

Method Detail

setSimilarityValue

public void setSimilarityValue(java.lang.Object category1,
                               java.lang.Object category2,
                               double similarityValue)

Adds a similarity value between the two values. This effectively adds the specified similarity value into the entry (category1, category2) as well as (category2, category1), automatically making the matrix symmetric.

Parameters:

category1 -

category2 -

similarityValue - The similarity value of the specified two values.

Returns:
