Simple ensemble

Description

A simple ensemble is a collection of workflows for which predictions will be combined in a simple way (e.g. by taking either the mean or median). Usually these workflows will consists each of the best version of a given model algorithm following tuning. The workflows are fitted to the full training dataset before making predictions.

Usage

simple_ensemble(...)

Arguments

...

not used, this function just creates an empty simple_ensemble object. Members are added with add_best_candidates()

Value

an empty simple_ensemble. This is a tibble with columns:

• wflow_id: the name of the workflows for which the best model was chosen

• workflow: the trained workflow objects

• metrics: metrics based on the crossvalidation resampling used to tune the models
