Logging Best Parameters and Learned Weights from Cross Validation
Hi! Is there a way to obtain the best parameter combination output from cross-validation operator? After running the cross validation on the train set, I need to log the best parameters and the weights for the features learned by the model. What operators should I use for this?

Loop Subsets of attributes and log result of each loop
Hi, I have a bunch of attributes / features in my dataset and want to find out which combination of features will train the best model. Therefore I am using the LoopSubsets Operator. I specified it to "min number of attributes" = 2, so I will get at least 1 feature and the label in each loop. I use the branch operator to…

CrossValidation logging performance
Hi I have noticed that the performance which is logged by the Log operator from the CrossValidation operator is actually microaverage while the standard deviation is logged from the regular (macro) performance, so these two values (Performance + Standard deviation do not match - these are two independent values. To log the…

Logging on the rapidminer server
Just playing around as a newbie with the rapidminer server. I have some questions on logging. When I run a process on the sever, I get less logging then when running locally. For instance : When I run a process with an exeute script step, I do not see any operator.getLog().log("whatever") entries. Also when using the Print…

I am getting an error as shown but no error is coming through split…

Logging operator executions
Hi RapidMiner Community, I've managed to deploy my process into a web service using RapidMiner Server. I think it will be beneficial if the web service can have a log just like a log4j. I am thinking to create a log for the web service so it will show something like this INFO [2019-03-29 14:55:56] Start A Prediction…
