"Apply a decision tree to calculate a label attribute"

voyz02

Hello everyone!

Firt of all, sorry if my english level isn't quite good... I have designed an analytical process that generates as last step a decision tree from a label attribute named Interesado (Interested in spanish)

My question es: How can I apply de decision tree to calculate the value of the label attribute in those rows that do not have this information?

For example, my decision tree made by Weka is:



And I want to apply this decision tree to calculate the value of label Interesado in this rows:



Is that possible?

Yes it is possible.  Estimate your model with the training data and then apply the model to the new dataset. Your lucky day; I teach one DM course in Spanish (check out these tutorials:

Just change the operator I used and replace it with the Weka Tree.
