Logging and analytics are crucial components in the lifecycle of machine learning (ML) models, particularly when it comes to monitoring performance and ensuring the reliability of predictions. Effective logging allows data scientists and engineers to track the data used in training, the parameters of the models, and the outcomes of various experiments. This is essential for reproducibility and for understanding how changes in data or model configurations affect performance.

MLflow is a popular tool that facilitates logging in ML workflows. It allows users to log datasets, parameters, metrics, and models, making it easier to manage experiments and track results over time. By logging the dataset used in a specific training run, you can ensure consistency when revisiting experiments for improvements or audits ². Additionally, logging can help identify issues such as overfitting or biases in the model, which can be addressed through further analysis and adjustments.

Incorporating analytics into the logging process enables teams to visualize performance metrics and gain insights into model behavior, which is vital for making informed decisions about model deployment and retraining strategies ¹.
