Tuning random forest hyperparameters with #TidyTuesday trees data

I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first steps in modeling to how to tune more complex models. Today, I’m using a #TidyTuesday dataset from earlier this year on trees around San Francisco to show how to tune the hyperparameters of a random forest model and then use the final best model. Here is the code I used in the video, for those who prefer reading instead of or in addition to video.

LASSO regression using tidymodels and #TidyTuesday data for The Office

I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first steps in modeling to how to tune more complex models. Today, I’m using this week’s #TidyTuesday dataset on The Office to show how to build a lasso regression model and choose regularization parameters! Here is the code I used in the video, for those who prefer reading instead of or in addition to video.

Preprocessing and resampling using #TidyTuesday college data

I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first getting started to how to tune machine learning models. Today, I’m using this week’s #TidyTuesday dataset on college tuition and diversity at US colleges to show some data preprocessing steps and how to use resampling! Here is the code I used in the video, for those who prefer reading instead of or in addition to video.

Hyperparameter tuning and #TidyTuesday food consumption

Last week I published a screencast demonstrating how to use the tidymodels framework and specifically the recipes package. Today, I’m using this week’s #TidyTuesday dataset on food consumption around the world to show hyperparameter tuning! 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 here is to predict which countries are Asian countries and which countries are not, based on their patterns of food consumption in the eleven categories from the #TidyTuesday dataset.

#TidyTuesday hotel bookings and recipes

Last week I published my first screencast showing how to use the tidymodels framework for machine learning and modeling in R. Today, I’m using this week’s #TidyTuesday dataset on hotel bookings to show how to use one of the tidymodels packages recipes with some simple models! Here is the code I used in the video, for those who prefer reading instead of or in addition to video.
