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.

Chapter 9: Fundamentals of Deep Learning Explainability

Explainability is providing selective human-understandable explanations for a decision provided by an automated system. In the context of this book, during the full life cycle of deep learning (DL) development, explainability should be emphasized as a first-class artifact, along with the other three pillars: data, code, and model. This is because different stakeholders and regulators, model developers, and final consumers of the model output may have different needs to understand how the data is used and why the model produces certain predictions or classifications. Without such understanding, it will be difficult to gain the trust of the consumers of the model output or to diagnose what could have gone wrong when model output results drift. This also means that explainability tools should be employed not only for explaining prediction results from a deployed model in production or during offline experimentation, but also for...
