Best way to combine probabilistic classifiers in scikit-learn

Question

I have a logistic regression and a random forest and I\'d like to combine them (ensemble) for the final classification probability calculation by taking an average.

Is t

Answer 1

NOTE: The scikit-learn Voting Classifier is probably the best way to do this now

OLD ANSWER:

For what it's worth I ended up doing this as follows:

class EnsembleClassifier(BaseEstimator, ClassifierMixin):
    def __init__(self, classifiers=None):
        self.classifiers = classifiers

    def fit(self, X, y):
        for classifier in self.classifiers:
            classifier.fit(X, y)

    def predict_proba(self, X):
        self.predictions_ = list()
        for classifier in self.classifiers:
            self.predictions_.append(classifier.predict_proba(X))
        return np.mean(self.predictions_, axis=0)
