Hi I have write machine learning use decision tree model. I create webapp that user can input and web will call to model by flask api and then show result on webapp but my result have only Yes/No. It possible if the result can show percentage how much this input will yes/no, Example Yes 76%
You could use predict_proba() as it returns the class probabilities of the input samples X.
probs = clf.predict_proba(X) # probs will output the probability of the prediction on each class.
You can read more about it in the documentation and in this other post with a similar question.
