Does this skill help with parallel processing?

Yes, it includes implementation patterns for doParallel and future backends to run tuning tasks across multiple CPU cores.

What are racing methods in model tuning?

Racing methods, like ANOVA racing, statistically compare parameter combinations during resampling and stop evaluating poor configurations early to save time.

How does Bayesian optimization differ from grid search?

While grid search explores a pre-defined set of points, Bayesian optimization uses previous results to intelligently predict and sample the most promising areas of the parameter space.

Which R packages does this skill support?

This skill focuses on the tidymodels ecosystem, specifically the tune, dials, and finetune packages for hyperparameter optimization.

Can I tune recipe steps as well as model parameters?

Absolutely. This skill covers using the tune() placeholder for both model specifications and preprocessing steps within a tidymodels recipe.
