There is no option to change the KMeans initialization inside GMM.py, and the default causes trouble

As reported in https://groups.google.com/forum/#!topic/bob-devel/Y61TTeiQQiY the default value for initialization_method in the KMeansTrainer constructor https://www.idiap.ch/software/bob/docs/latest/bob/bob.learn.em/master/py_api.html#bob.learn.em.KMeansTrainer inside GMM.py: https://gitlab.idiap.ch/bob/bob.bio.gmm/blob/master/bob/bio/gmm/algorithm/GMM.py#L84 causes trouble.

Two things to do:

  • make the initialization_method a parameter of the bob.bio.gmm.algorithm.GMM constructor, with default value KMEANS_PLUS_PLUS
  • check that the tests pass -- different KMeans initialization will change results and corresponding reference values in the test cases
