    The speaker is a solution architecht solution at RapidMiner; I haven't time to look the full workshop. I am sure that it is solid stuff.

    Bonne journée,

    yep that's a good video. There are also sample processes in the product itself (go to Help under Execute Python) and some samples also in the Community Repository.

    I think that can get you started.

     

    However it is a very bad idea to use the scripts inside cross-validation (or inside any loop in general), because that makes the scripts be executed multiple times with a huge overhead:

     

    • Python/R initialization
    • Conversion from example set to data frame
    • Processing by the Python/R interpreter, most of the times with only one core
    • Conversion from data frame to RapidMiner example set

     

    If you want to use it, bring the iteration or cross validation into the script (for example with the caret package in R or Scikit Learn in Python).

     

    Best regards,

    Sebastian
