Trying to debug gaussian_components_diag.
Still trying to figure out gaussian_components_diag.
Added test for test_gaussian_components_diag.test_prod_students_t.
Added further test for bayes_gmm.gaussian_components_diag.
Added further test for bayes_gmm.gaussian_components_diag.
Added tests; updated readme.
Busy with log_marg_k for diag.
Think almost done with GaussianComponentsDiag.
Going to update IGMM to allow diagonal covariance.
Added igmm_diag_2d_demo.py.
Added fbgmm_diag_2d_demo.py .
Extended IGMM and FBGMM models to allow for only diagonal covariance.
