GridSearchCV uses predict or predict_proba?
Grid Search CV has both the predict and the predict_proba functions.
If you consider a binary classification problem, predict will have the values of 0 or 1. While, Predict_proba will have the probability values of it being 0 or 1.
predict_proba will have an array output like [0.23 0.77]
It works for the huber and log, however only the logarithm has a predict_proba? How it works? I used roc_auc_score.
