Mastering Azure Machine Learning - Second Edition

Overview of this book

Azure Machine Learning is a cloud service for accelerating and managing the machine learning (ML) project life cycle that ML professionals, data scientists, and engineers can use in their day-to-day workflows. This book covers the end-to-end ML process using Microsoft Azure Machine Learning, including data preparation, performing and logging ML training runs, designing training and deployment pipelines, and managing these pipelines via MLOps. The first section shows you how to set up an Azure Machine Learning workspace; ingest and version datasets; as well as preprocess, label, and enrich these datasets for training. In the next two sections, you'll discover how to enrich and train ML models for embedding, classification, and regression. You'll explore advanced NLP techniques, traditional ML models such as boosted trees, modern deep neural networks, recommendation systems, reinforcement learning, and complex distributed ML training techniques - all using Azure Machine Learning. The last section will teach you how to deploy the trained models as a batch pipeline or real-time scoring service using Docker, Azure Machine Learning clusters, Azure Kubernetes Services, and alternative deployment targets. By the end of this book, you’ll be able to combine all the steps you’ve learned by building an MLOps pipeline.

Chapter 12: Distributed Machine Learning on Azure

In the previous chapter, we learned about hyperparameter tuning through search and optimization, using HyperDrive as well as Automated Machine Learning as a special case of hyperparameter optimization, involving feature engineering, model selection, and model stacking. Automated Machine Learning is machine learning as a service (MLaaS), whereby the only input is your data, an ML task, and an error metric. It's hard to imagine running all experiments and parameter combinations for Automated Machine Learning on a single machine or a single CPU/GPUwe are looking into ways to speed up the training process through parallelization and distributed computing.

In this chapter, we will look into distributed and parallel computing algorithms and frameworks for efficiently training ML models in parallel. The goal of this chapter is to build an environment in Azure where you can speed up the training process of classical ML and deep learning...
