How to properly refit recursive models?

1

I've been trying out some recursive models, but I can't find any examples that show how to use refitting to all data after training on training data with a train...

Thank you for your interesting application! I'd like to use your application in my research, but need to include a description for the journal of how the gain is calculated...

step_select_boruta and step_select_mrmr need method for internally handling NAs

2

step_select_boruta and step_select_mrmr cannot handle data with missing/NA values. This requires the user to remove or impute NAs in a recipe step prior to the feature selection step in order...

In an attempt to understand how the groups were created in `shap.prep.stack.data()`, I attempted to reproduce the grouping the function calculates on my own with the `stats::hclust()` function. `stats::hclust()` and...

Variable importance plot lists only original variables, not one-hot-encoded variables, when permutation importance calculated with `model_parts()` and `explain_tidymodels()` functions?

2

I am using `explain_tidymodels()` to compute variable importance. I have a workflow which includes a recipe with a `step_dummy()` step. I'm trying to understand why the associated variable importance calculated...

Cannot reproduce measure (delta L) values of featureImportance for individual observations outside of featureImportance

3

I would like to get the local feature importance of the ith observation for individual variables as described in Casalicchio et al. section 4 lines 7-8 by integrating the ICI...
