WebApr 14, 2024 · Dimensionality reduction simply refers to the process of reducing the number of attributes in a dataset while keeping as much of the variation in the original dataset as possible. It is a data preprocessing step meaning that we perform dimensionality reduction before training the model. In this article, we will discuss 11 … WebStep 7: Tune the Model. Tuning is where the tidymodels ecosystem of packages really comes together. Here is a quick breakdown of the objects passed to the first 4 arguments of our call to tune_grid () below: “object”: xgboost_wf which is a workflow that we defined by the parsnip and workflows packages.
