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.

Summary

In this chapter, you learned how to use and configure Azure Machine Learning pipelines for splitting an ML workflow into multiple steps using pipeline and pipeline steps for estimators, Python execution, and parallel execution. You configured pipeline input and output using Dataset and PipelineData and managed to control the execution flow of the pipeline.

As another milestone, you deployed the pipeline as PublishedPipeline to an HTTP endpoint. This lets you configure and trigger the pipeline execution with a simple HTTP call. Next, you implemented automatic scheduling based on a time frequency, as well as a reactive schedule based on changes in the underlying dataset. Now, the pipeline can rerun your workflow when the input data changes without any manual interaction.

Finally, we also modularized and versioned a pipeline step so that it can be reused in other projects. We used InputPortDef and OutputPortDef to create virtual bindings for data sources and sinks. In the...
