Method Detail

getSimilarity_intern

protected abstract float getSimilarity_intern(float[] a,
                                              float[] b)
                                       throws SizeMismatchException

return the computed similarity (or distance, respectively) between the two vectors. Which of distance or similarity is computed by this measure can be queried by calling getType().

Parameters:

a - vector representing the first artist

b - vector representing the second artist

Returns:

Throws:

SizeMismatchException

getType

public SimMeasure.SimType getType()

Indicates if this similarity measure returns similarities by means of similarities, or by means of distances.

Returns:

getName

public String getName()

getSimilarity

public float getSimilarity(float[] a,
                           float[] b)
                    throws SizeMismatchException

Throws:
