[SOLVED] Condtion Based Process Execution

Question

Hi,

I'm not sure if this is possible with RapidMiner but I'll ask anyway - RapidMiner continues to surprise me with it's limitless capabilities.

I want to execute an existing process using the "Execute Process" operator but only under 1 condition.
For example, If att1 contains X then execute process.

Thanks again!

Cheers,

Hi Marcin,

Thanks for that. I also figured out another way to do it using the "Select Subprocess" Operator. I used some macros to generate the "1" or "2" value required to execute the different processes. I think your solution is probably more robust though.

Cheers,
Rowan

Hey, RapidMiner has a "Branch"-operator which you can use for this purpose. Inside this operator you will see two subprocesses "then" and "else". Depending on the condition either the "then"- or the "else"-subprocess will be executed. So in the "then"-case you can execute your process. Regarding your condition you have to hack a little bit, since the "attribute_value_filter" tests all values for a value, so you can not check if it contains a value directly. But with the help of the "Filter Example" operator you can filter out all example with this value and use the "min_examples" condition. See the example process and replace the log-operators inside the branch operator accordingly. Best Marcin
