Overview of this book

The book starts with an overview of the deep learning (DL) life cycle and the emerging Machine Learning Ops (MLOps) field, providing a clear picture of the four pillars of deep learning: data, model, code, and explainability and the role of MLflow in these areas. From there onward, it guides you step by step in understanding the concept of MLflow experiments and usage patterns, using MLflow as a unified framework to track DL data, code and pipelines, models, parameters, and metrics at scale. You’ll also tackle running DL pipelines in a distributed execution environment with reproducibility and provenance tracking, and tuning DL models through hyperparameter optimization (HPO) with Ray Tune, Optuna, and HyperBand. As you progress, you’ll learn how to build a multi-step DL inference pipeline with preprocessing and postprocessing steps, deploy a DL inference pipeline for production using Ray Serve and AWS SageMaker, and finally create a DL explanation as a service (EaaS) using the popular Shapley Additive Explanations (SHAP) toolbox. By the end of this book, you’ll have built the foundation and gained the hands-on experience you need to develop a DL pipeline solution from initial offline experimentation to final deployment and production, all within a reproducible and open source framework.

Tracking data versioning in Delta Lake

In this section, we'll learn how data is tracked in MLflow. Historically, data management and versioning are usually considered as being different from machine learning and data science. However, the advent of data-centric AI is playing an increasingly important role, particularly in DL. Therefore, it is critical to know what and how data is being used to improve the DL model. In the first data-centric AI competition, which was organized by Andrew Ng in the summer of 2021, the requirements to become a winner were not about changing and tuning a model, but rather improving the dataset of a fixed model (https://https-deeplearning-ai.github.io/data-centric-comp/). Here is a quote from the competition's web page:

"The Data-Centric AI Competition inverts the traditional format and asks you to improve a dataset, given a fixed model. We will provide you with a dataset to improve by applying data-centric techniques such as fixing incorrect...
