fast_classification: Generate Model Specification calls to parsnip

Description

Creates a list/tibble of parsnip model specifications.

Usage

fast_classification(
  .data,
  .rec_obj,
  .parsnip_fns = "all",
  .parsnip_eng = "all",
  .split_type = "initial_split",
  .split_args = NULL,
  .drop_na = TRUE
)

Value

A list or a tibble.

Arguments

.data

The data being passed to the function for the classification problem

.rec_obj

The recipe object being passed.

.parsnip_fns

The default is 'all' which will create all possible classification model specifications supported.

.parsnip_eng

the default is 'all' which will create all possible classification model specifications supported.

.split_type

The default is 'initial_split', you can pass any type of split supported by rsample

.split_args

The default is NULL, when NULL then the default parameters of the split type will be executed for the rsample split type.

.drop_na

The default is TRUE, which will drop all NA's from the data.

Details

With this function you can generate a tibble output of any classification model specification and it's fitted workflow object. Per recipes documentation explicitly with step_string2factor() it is encouraged to mutate your predictor into a factor before you create your recipe.
