Model training examples
This section includes examples showing how to train machine learning models on Databricks using many popular open-source libraries.
You can also use AutoML, which automatically prepares a dataset for model training, performs a set of trials using open-source libraries such as scikit-learn and XGBoost, and creates a Python notebook with the source code for each trial run so you can review, reproduce, and modify the code.
