I have the below code where i have three attributes i am trying to tune. They are all called the same thing. Does anyone know how i would fit them into tuning grid?
For example the tuning paramter for PCA, correlation and bucketing of character attributes is called
threshold. I would like to somehow identify each tuning parameter associated with each attribute.
Below is the psuedocode
library(tidymodels) library(tidyverse) library(modeldata) data("attrition") mod_data <- attrition att_rec <- recipe(Attrition ~ ., data = mod_data) %>% step_other(all_nominal_predictors(), threshold = tune()) %>% step_unknown(all_nominal_predictors()) %>% step_dummy(all_nominal_predictors(), one_hot = TRUE) %>% step_zv(all_predictors()) %>% step_corr(all_numeric_predictors(), threshold = tune()) %>% step_pca(all_numeric_predictors(), threshold = tune()) lasso_spec <- linear_reg(penalty = tune(), mixture = 1) %>% set_engine("glmnet") lambda_grid <- grid_regular(penalty(), threshold() # but we have three thresholds so how do we set them levels = 50) # Add to the workflow and run.......
Any help would be greatly appreciated.
Thank you for your time
