Observed classes

[gintriago12]

Hi,

Where does a model such as Logistic Regression, or the ensemble ADWINBaggingClassifier store the observed classes?

The Hoeffding Adaptive Tree stores the observed clases in the attribute classes. However, the models mentioned first do not have such attribute.

Thanks for your help.

Best,

Hi @gintriago12, Logistic Regression or ADWINBaggingClassifier do not store the observed classes. Logistic Regression and ADWINBaggingClassifier do not needs such attribute to learn or predict. If you need to know the frequency of the target variable during training, you can use collections.Counter in the training loop. 🙂

Thanks Raphaelsty!

Also, LogisticRegression is a binary classifier, so the classes are implicitely False and True.
