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.

Summary

In this chapter, we reviewed explainability in AI/ML through an eight-dimension categorization. Although this is not necessarily a comprehensive or exhaustive overview, this does give us a big picture of who to explain to, different stages and scopes to explain, various kinds of input and output formats of the explanation, common ML problems and objectives types, and finally, different post-hoc explainability methods. We then provided two concrete exercises to explore the SHAP and Transformers Interpret toolboxes, which can provide perturbation and gradient-based feature attribution explanations for NLP text sentiment DL models.

This gives us a solid foundation for using explainability tools for DL models. However, given the active development of XAI, this is only the beginning of using XAI in DL models. Additional explainability toolboxes such as TruLens (https://github.com/truera/trulens), Alibi (https://github.com/SeldonIO/alibi), Microsoft Responsible AI Toolbox (https...
