Automatic Machine Learning

Description

auto_ml() defines an automated searching and tuning process where many models of different families are trained and ranked given their performance on the training data.

\Sexpr[stage=render,results=rd]{parsnip:::make_engine_list("auto_ml")}

More information on how parsnip is used for modeling is at https://www.tidymodels.org/.

Usage

auto_ml(mode = "unknown", engine = "h2o")

Arguments

mode

A single character string for the prediction outcome mode. Possible values for this model are "unknown", "regression", or "classification".

engine

A single character string specifying what computational engine to use for fitting.

Details

This function only defines what type of model is being fit. Once an engine is specified, the method to fit the model is also defined. See set_engine() for more on setting the engine, including how to set engine arguments.

The model is not trained or fit until the fit() function is used with the data.

Each of the arguments in this function other than mode and engine are captured as quosures. To pass values programmatically, use the injection operator like so:

value <- 1
auto_ml(argument = !!value)
