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.

Azure Cognitive Services and Custom Vision

If you are dealing with a well-defined general ML problem, such as classification, object or face detection in computer vision, Optical Character Recognition (OCR) and handwriting recognition, speech-to-text and text-to-speech, translation, spell-checking, key word and entity extraction, or sentiment analysis, the chances are high that these services have already been implemented and battle-tested in Azure. In a lot of cases, it greatly saves you time, resources, and effort by reusing these services instead of training similar models from scratch.

If your problem space is very general—such as detecting and matching faces from a camera image to an ID image—or detecting adult content in user-uploaded media, then you can look into Cognitive Services. The Cognitive Services website features demos for almost all the APIs and you can go and try them out for your use case.

If your domain is very specific but uses one of the previously...
