In this live training, we’ll motivate the benefits of dimensionality reduction while exploring predictors of credit scores. Using ggplot2, we’ll demonstrate how UMAP can extract information-rich features that help to group credit scores. Then, we’ll build UMAP into a tidymodels workflow that fits a decision tree model to predict credit scores. We’ll evaluate the performance of models with and without UMAP dimensionality reduction.
