Descrição do Curso
Welcome to the tidyverse! In this course, you will continue on your journey to learn the tidyverse and apply your knowledge to machine learning concepts.
This course is ideal if you’re looking to integrate R's Tidyverse tools into your machine learning workflows.
The course begins by introducing the List Column Workflow (LCW), a method for managing multiple models within a single dataframe. It also covers using the broom package to tidy up and explore model outputs, making the complex results more interpretable.
You will use packages like tidyr and purrr to handle complex data manipulations and model evaluations, ensuring a tidy and systematic approach to machine learning.
By the end of the course, you will have a strong foundation in applying Tidyverse principles to machine learning, enabling them to build, tune, and evaluate models efficiently in a tidy and reproducible manner.

Foundations of "tidy" Machine learning
GratuitoThis chapter will introduce you to the backbone of machine learning in the tidyverse, the List Column Workflow (LCW). The LCW will empower you to work with many models in one dataframe.
This chapter will also introduce you to the fundamentals of the broom package for exploring your models.Foundations of "tidy" machine learning50 xpNesting your data100 xpUnnesting your data100 xpExplore a nested cell100 xpThe map family of functions50 xpMapping your data100 xpExpecting mapped output100 xpMapping many models100 xpTidy your models with broom50 xpThe three ways to tidy your model50 xpExtracting model statistics tidily100 xpAugmenting your data100 xp - 2
Multiple Models with broom
This chapter leverages the List Column Workflow to build and explore the attributes of 77 models. You will use the tools from the broom package to gain a multidimensional understanding of all of these models.
