Is their a way to get the exact column names the model used for dummification in the predicted data-set
dummy:variable_name:variable_value or something like variable_name_variable_value ?
Thank you in advance!
You can't output those names in a dataset. However, there are available when you interpret some model results. For exemple: export coefficients of a logistic regression or export variable importance of a random forest.
You can also do the dummification yourself within a prepare recipe using the "unfold" preprocessor. Beware this might lead to huge datasets.
Thank you for your quick Answer.
for my case as the dummification is available in the model part, I think it is better to do it at this level.
and find it interesting to have an option to output dataset with dummified variables.
