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.

Exploring the SHAP Explainability toolbox

For our learning purpose, let's review some popular explainability toolboxes while experimenting with some examples. Based on the number of GitHub stars (16,000 as of April 2022, https://github.com/slundberg/shap), SHAP is the most widely used and integrated open source model explainability toolbox. It is also the foundation explanation tool that is integrated with MLflow. Here, we would like to run a small experiment to get some hands-on experience on how this works. Let's use a sentimental analysis NLP model to explore how SHAP can be used for explaining the model behavior:

  1. Set up the virtual environment on your local environment after checking out this chapter's code from GitHub. Running the following command will create a new virtual environment called dl-explain:
    conda env create -f conda.yaml

This will install SHAP and its related dependencies such as matplotlib in this virtual environment. Once this virtual...
