I built a process in Rapidminer Studio (classification with decision tree/neural net), I would like to load this process and run it with different datasets in a Java console application. I read about this here, but I didn't really found a great tutorial/documentation, how to do this, the basic things (load process, change properties, change the training model, ... ). Any advice would be helpful.

    Your best bet is to use RapidMiner Server or getting an OEM license.

    @Thomas_Ott that's not right.As long as it part of the open core you can do this. I think there is no explicit documentation on it though.

     

    Easy way might be to use the CLI.

     

    Best,

    Yes, I'd like a simple cli, to load the process and run the process, but I don't really know, how to load a process that I made in Rapidminer, and things like that.

    Hi,

     

    rm already has an CLI. Just go for 

    rapidminer -f myfile.rmp

    or

    rapidminer //Local Repository/folder/myprocess

    .

    That works. You can also provide macros if you want to.

     

    Best,

    Martin

    Thanks! These informations were really helpful.

     

     

    RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE); 
    RapidMiner.init(); 
    Process process = new Process(new File("/MyProcessFile.rmp"));
    System.out.println(process.run());

     

     Finally I wrote this, after that I got the result. Maybe it'll be useful for others.
