select_best_hyperparameters: Select the best hyperparameter set according to a given...

In mdneuzerling/YelpMetaflow: What the Package Does (One Line, Title Case)

Description

Metaflow saves artefacts as pickle files, which prevents us from using nested tibbles. Unfortunately, tune relies on nested tibbles to store its results. We instead use collect_metrics to store simple tibbles that are compatible with pickle. Unfortunately, this means we cannot rely on tune's functions for extracting optimal hyperparameter sets and must write our own.

Usage

select_best_hyperparameters(hyperparameter_results, metric = "rmse")

Arguments

hyperparameter_results	A tibble of hyperparameter results collected with tune::collect_metrics
metric	A metric to minimise. Defaults to "rmse".

Value

named list
