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?
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…
Hello, I am using a log file to record my modeling results(i.e, training, recall, precision etc.). It works well but I want to convert that to example set so that I can export it later. I am using Log to Data operator but it doesn't produce the output I was looking for. I am using them inside a Optimize parameter process.…
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…
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…
Hi, I have created machine learning classification models using Automodel and want to test the sample data using retrieve operator and putting it as unlabelled data in Apply operator instead of unlabelled data coming from split validation operator. I am getting an error as shown but no error is coming through split…
Hi, I am relatively new to RapidMiner and currently using it to load data to RedShift. I need to log the username under which a process is executing. I will later on log that username and datetime in a log table. I have trouble getting the username as a macro. I got some reference that I maybe able to use %{_ra_user} but I…
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…
