Re: How can I build a model to find the best predictor for 5 different targets and 30 predictors?
Hello @Neuronerd You can build a multi-class classification model. If you are new to classification, I recommend you look at videos on "Rapidminer Academy" The below videos on rapidminer yo… (View Post)2 -
get_date function of Generate Attributes Operator
I am trying to understand how the generate an Hour of the Day attribute from a Date attribute. The date attribute looks like this: Feb 4, 2020 1:52:34 AM EST. I have been trying to determine what are… (View Post)1 -

It looks like this is the image mining extension. Unfortunately this extension is no longer maintained by it's developers (not directly RapidMiner) and it has many issues that we can't fix. Is it man… (View Post)1 -
Re: adding labels to a polynominal variable
Hi @Mori111 , you can easily rename/replace your categories with other values by using the Replace operator.To specify an attribute as label, you can use the Set Role operator and select "label&… (View Post)2 -
adding labels to a polynominal variable
I have a polynominal variable, Income, with 4 categories: <25, 25-49, 50-75. 75+. I want to add a label to each category. For example, for <25, I want to add (or replace it with) a label "… (View Post)1 -
Re: Cross Validation - Macro Averaged Precision Calculation
@pipaso have you tried checking the "use local random seed" box? It's possible you're getting different results due to different random seeds. You can use this feature to keep this constant. (View Post)1 -
Re: Cross Validation - Macro Averaged Precision Calculation
Thanks @David_A, I have already read that answer. I have done the same thing that the answer suggested, but the results are different. For example, the average precision must be (0.8516916+0.8314766+… (View Post)1 -
Re: Test model for different outcome variable
hi @aksaha I'm not sure exactly what you mean here. Do you want to rebuild the model with a new predicted class, or do you want to score the model on new data with the same predicted class? The latte… (View Post)2 -
Test model for different outcome variable
Hi, I have rapidminer deep learning predictive model for a output variable, I want to see how to the model performs to a different outcome variable using the same learning information. What would be … (View Post)1 -
Re: How can I tackle the problem of naming examplesets?
@pblack476 I think the short answer at the moment is that if you're building that many ExampleSets in production, we recommend writing them into a database as tables. The results view was never desig… (View Post)1
