Prediction for a model

edited November 2024 in Community Q&A
I checked your two datasets X and Y, both have "Class" attribute. This class has labels "0" and "1". I want to combine these two datasets and make predictions as a single model. Can someone share the steps for this task.

    Hi @indu,

    mmhh...  I don't understand what you want to do...
    In order we can help you, can you describe what you have and what you want to obtain.
    Please share your data...

    Regards,

    @indu,
    It's very easy : 

    Use an Append operator to combine the 2 datasets.

    Here a sample process with your 2 combined datasets including a X-validation with a Decision Tree : 

    <?xml version="1.0" encoding="UTF-8"?><process version="9.5.000">

    when i split the data, i get some errors. please use the process attached below.

    @indu

    You don't set the parameters of the Split Data operators, that's why RM is raising an error.
    I must admit that I don't understand what you want to do with these Split Data operators...

    Please use the working process I shared in my last post.
