hai_auto_cubist: Boilerplate Workflow

In healthyR.ai: The Machine Learning and AI Modeling Companion to 'healthyR'

Boilerplate Workflow

Description

This is a boilerplate function to create automatically the following:

• recipe

• model specification

• workflow

• tuned model (grid ect)

Usage

hai_auto_cubist(
  .data,
  .rec_obj,
  .splits_obj = NULL,
  .rsamp_obj = NULL,
  .tune = TRUE,
  .grid_size = 10,
  .num_cores = 1,
  .best_metric = "rmse"
)

Arguments

.data	The data being passed to the function. The time-series object.
.rec_obj	This is the recipe object you want to use. You can use hai_cubist_data_prepper() an automatic recipe_object.
.splits_obj	NULL is the default, when NULL then one will be created.
.rsamp_obj	NULL is the default, when NULL then one will be created. It will default to creating an rsample::mc_cv() object.
.tune	Default is TRUE, this will create a tuning grid and tuned workflow
.grid_size	Default is 10
.num_cores	Default is 1
.best_metric	Default is "rmse". The only .model_type you can use with Cubist is regression so use hai_default_regression_metric_set() to get the available metrics. Because of this the .model_type parameter is omitted from this function.

Details

This uses the parsnip::cubist_rules() with the engine set to cubist
