While the previous chapter focused on managing datasets with DVC, developing machine learning models presents another set of management challenges. Training often involves numerous iterations with adjustments to hyperparameters, code, or feature engineering. Without a structured method, it becomes difficult to recall which settings led to specific results or to reproduce a past experiment accurately.

This chapter introduces MLflow Tracking as a solution for systematically recording your modeling work. We will cover how to:

• Set up the MLflow environment.
• Modify your training scripts to log key information: parameters, metrics, and artifacts like models or plots.
• Group related training attempts into experiments.
• Utilize the MLflow interface to view, search, and compare the outcomes of different runs.

Adopting these practices provides a clear record of your development process, supporting reproducibility and improving model iteration efficiency.
