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.

Understanding patterns of DL inference pipelines

As the model development enters the stage of implementing an inference pipeline for the upcoming production usage, it is important to understand that having a well-tuned and trained DL model is only half the success story for business AI strategy. The other half includes deploying, serving, monitoring, and continuously improving the model after it goes into production. Designing and implementing a DL inference pipeline is the initial step toward the second half of the story. While the model has been trained, tuned, and tested on curated offline datasets, now it needs to handle prediction in two ways:

  • Batch inference: This usually requires some scheduled or ad hoc execution of an inference pipeline for some offline batch of observational data. The turnaround time for producing prediction results is daily, weekly, or other schedules.
  • Online inference: This usually requires a web service for real-time execution of an inference...
