Multinomial classification with tidymodels and #TidyTuesday volcano eruptions
Lately I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first steps in modeling to how to evaluate complex models. Today’s screencast demonstrates how to implement multiclass or multinomial classification using with this week’s #TidyTuesday dataset on volcanoes. 🌋 Here is the code I used in the video, for those who prefer reading instead of or in addition to video. Explore the data Our modeling goal is to predict the type of volcano from this week’s #TidyTuesday dataset based on other volcano characteristics like latitude, longitude, tectonic setting, etc.
