Hello, I am using automodel in rapid miner studio. The problem I have is that I have a categorical variable, therefore one hot encoding is needed. However, the number of categories is more than 50 , what can I do so the algorithm takes it into consideration and does not ignore it

    Hi,
    you can use the operator Replace Rare to replace Rare values with OTHER.

    Oh, alternatively you can use Target Encoding of course.

    Hi,
    yes, or just do it up front with a small prep process. Please shoot me or Vlad an e-mail if you want to do this together with us.

    BR,
    Martin
