Hi, I want to build and screen multiple models, and in one of the workflows, i'd like to use the hardhat blueprint for sparse dataset.
I primarily followed these 2 links
In the example below: the setting of workflow_set
no_pre_proc <- workflow_set( preproc = list(simple = model_vars), models = list(MARS = mars_spec, CART = cart_spec, CART_bagged = bag_cart_spec, RF = rf_spec, boosting = xgb_spec, Cubist = cubist_spec) )
In this example, is the setting of workflow (not workflow_set)
wf_sparse <- workflow() %>% add_recipe(text_rec, blueprint = sparse_bp) %>% add_model(lasso_spec) wf_default <- workflow() %>% add_recipe(text_rec) %>% add_model(lasso_spec)
How do i introduce into the workflow_set the option of "blueprint = sparse_bp"?
