    @Shahessi_10,

    Here, you can find a process doing what you want to achieve.
    Basically I build a DT model with the examples with no missing value (Price) and then I'm applying this model
    to the examples with missing values (Price).

    Hope this helps,

    Regards,

    Lionel

    Hi @Shahessi_10,

    In case of error, don't forget that you can submit directly your data to AutoModel.
    In attached file a working process produced by AutoModel which uses GBT (it was the best model for your regression model)
    You can notice that I removed the "att1" attribute which is basically an Id... ==> please check the GBT_regression_automodel.rmp process.

    Otherwise I tried to rebuild your process you showed in the picture (with the DT model) ==> You can check the Decision_tree_regression.rmp process in attached file. I set the "att1" attribute as "ID" as well.

    Hope this helps,

    Regards,

    Lionel
