Optimize Parameters in RapidMiner

In this video, we see how to use two operators that allow you to adjust the parameters of your algorithms (and other operators if desired): Optimize Parameters (Grid) and Optimize Parameters (Evolutionary).

Hi! very nice video and very usefull! My question is, can i use Optimize Parameters (Grid) for logistic regression model or only for decision tree? Because i cannot file a single information on which parameters to use in that case

Yes, you can use it for any algorithm operator that has configurable parameters. Logistic regression doesn't have a lot of options, but you can change your alpha & lambda levels, set processing limits, and several other options.
