The fastest way to get started with machine learning in Databricks is to open the model training tutorial notebook. On the start page, click Start guide at the upper right. The notebook illustrates many of the benefits of using Databricks for machine learning, including tracking model development with MLflow and parallelizing hyperparameter tuning runs. The notebook steps through loading data, training and tuning a model, comparing and analyzing model performance, and using the model for inference.
