After I posted my efforts to use MLflow to serve a model with R, I was worried that people may think I don’t like MLflow. I want to declare this: MLflow is awesome. I’ll showcase its model tracking features, and how to integrate them into a tidymodels model. The Tracking component of MLflow can be used to record parameters, metrics and artifacts every time a model is trained. All of this information is presented in a very nice user interface.
