Mastering Azure Machine Learning

By: Christoph Körner, Kaijisse Waaijer

Overview of this book

The increase being seen in data volume today requires distributed systems, powerful algorithms, and scalable cloud infrastructure to compute insights and train and deploy machine learning (ML) models. This book will help you improve your knowledge of building ML models using Azure and end-to-end ML pipelines on the cloud. The book starts with an overview of an end-to-end ML project and a guide on how to choose the right Azure service for different ML tasks. It then focuses on Azure Machine Learning and takes you through the process of data experimentation, data preparation, and feature engineering using Azure Machine Learning and Python. You'll learn advanced feature extraction techniques using natural language processing (NLP), classical ML techniques, and the secrets of both a great recommendation engine and a performant computer vision model using deep learning methods. You'll also explore how to train, optimize, and tune models using Azure Automated Machine Learning and HyperDrive, and perform distributed training on Azure. Then, you'll learn different deployment and monitoring techniques using Azure Kubernetes Services with Azure Machine Learning, along with the basics of MLOps—DevOps for ML to automate your ML process as CI/CD pipeline. By the end of this book, you'll have mastered Azure Machine Learning and be able to confidently design, build and operate scalable ML pipelines in Azure.

Validating your code, data, and models

When implementing a CI/CD pipeline, you need to make sure you have all the necessary tests in place to deploy your newly created code with ease and confidence. Once you are running a CI or a CI/CD pipeline, the power of automated tests will become immediately evident. It not only protects certain pieces of code from failing while you are developing them, but it also protects your entire process—including the environment, data requirements, model initialization, optimization, resource requirements, and deployment—for the future.

When implementing a validation pipeline for our ML process, we align ourselves with the classical application development principles:

  • Unit testing
  • Integration testing
  • End-to-end testing

We can translate these testing techniques directly to input data, models, and the application code of the scoring service.
