I'd like to cross-validate my gaussian mixture model. Currently I use sklearn's cross_validation method as below.
clf = GaussianMixture(n_components=len(np.unique(y)), covariance_type='full')
cv_ortho = cross_validate(clf, parameters_train, y, cv=10, n_jobs=-1, scoring=scorer)
I see that cross_validation is training my classifier with y_train making it a supervised classifier.
try:
if y_train is None:
estimator.fit(X_train, **fit_params)
else:
estimator.fit(X_train, y_train, **fit_params)
However, I wanted to cross-validate an unsupervised classifier clf.fit(parameters_train). I understand that the classifier then assigns its own class labels. Since, I have two distinguished clusters (see image) and y I can decipher the corresponding labels. Then cross-validate. Is there a routine in sklearn which does this?
A routine similar to this example: https://scikit-learn.org/stable/auto_examples/mixture/plot_gmm_covariances.html
