How to obtain model weights for features selected by Automatic Feature Engineering operator?

Hi everyone,

I'm new to the Rapidminer software and I need some help with the Automatic Feature Engineering operator.

The question is how to get the weights for each selected feature from the Automatic Feature Engineering operator? Basically, the operator is trying all combinations of features and select the best performing one, and is there any way that I can save that specific model or the weights associated with each feature?

The purpose of doing it is that I want to see, in 30 runs, what is the frequency of occurrence for selected features and also the average weight for them, then I would generate a 2-dimensional plot and pick features with both more occurrence time and greater average weight.

The reason I'm doing this is that each time I run the operator it selects different features and I would like to have a validation process for the feature selection.

Thanks in advance,
