Decision Tree

我把一些数据做出决定n tree. It had about 200 rows and had missing values as well. Rapidminer made a decision tree with good branches 2-3 times with it but I changed the label of one column and decision tree was reduced to 2 branches after that. The weight of different attributes also changed and now I am not able to make that previous tree again. Can someone help me?

    Hello@Lalit9_

    Can you provide us with your XML code (View --> Show Panel --> XML) for deeper understanding?

    Thanks

    Hello@Lalit9_
    First of all it is always good to keep a back up version of your data and working on copies, in order to prevent many events.
    Secondly with the change you did, it is possible that the model works different on your dataset. Although when you choose a decision tree, you can set the attributes of the tree like depth etc. So maybe you changed something there.
    I hope it helps.
