MLflow is a platform for the “machine learning cycle”. It’s a suite of tools for managing models, with tracking of hyperparameters and metrics, a registry of models, and options for serving. It’s this last bit that I’m going to focus on today. I haven’t been able to find much discussion or documentation about MLflow’s support for R. There’s the RStudio MLflow example, but I wanted to see if I could use MLflow to serve something more complex.
