ID3 - Novice question
Hello,
I am very new to rapid miner and have just finished reading the RM tutorial (PDF).
I have a homework where an ID3 algortithm is to be applied to set of data made out of yeses and nos in an excel sheet.
I apply the ID3 algorithm and get a decision tree. It is Ok till here. But How do I get RapMin to give me coulmn of his own results preferably in an excel sheet.
I tried this: I named a coulumn as rapid and assigned 'prediction' attribute and used write excel operator to save the data in an xls format. But I just got the same sheet that I originally imported.
Thank you in advance.
