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.

Section 5 – Deep Learning Model Explainability at Scale

In this section, we will learn about the foundational concepts of explainability and explainable artificial intelligence (XAI) and how to implement deep learning (DL) explainability with MLflow. We will start with an overview of the eight dimensions of explainability and then learn how to use SHapley Additive exPlanations (SHAP) and Transformers Interpret to perform explainability for a natural language processing (NLP) pipeline. Furthermore, we will learn and analyze the current MLflow integration with SHAP to understand the trade-offs and avoid potential implementation problems. Then, we will show how to implement SHAP using MLflow's logging APIs. Finally, we will learn how to implement a SHAP explainer as an MLflow Python model and then load it as either a Spark UDF for batch explanation or as a web service for online Explanation-as-a-Service (EaaS).
