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.

In this section, we will learn how to implement and deploy a multi-step inference pipeline for production usage. We will start with an overview of four patterns of inference workflows in production. We will then learn how to implement a multi-step inference pipeline with preprocessing and postprocessing steps around a fine-tuned deep learning (DL) model using MLflow PyFunc APIs. With a ready-to-deploy MLflow PyFunc-compatible DL inference pipeline, we will learn about different deployment tools and hosting environments to decide which tool to use for a specific deployment scenario. We will then implement and deploy a batch inference pipeline using MLflow's Spark user-defined function (UDF). From there on, we will focus on deploying a web service using either MLflow's built-in model serving tool or Ray Serve's MLflow deployment plugin. Finally, we will show a complete step-by-step guide to deploying...
