I tried the decision tree support in Datameer smart analytics. I can enter my data for training and the sheet shows me how the trained tree predicts on the training data. I found no way to use the trained decision tree to classify new data. So I can see, that my problem is well suited for decision trees. I also can see the used features and splits in the graph. I could translate that into a big nested if-if-if... formular and would make a lot of syntax errors. Is there any smarter solution that I have overlooked? If not, could you handle this as a change request, to offer classification of data by a trained decision tree.
