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.

Automatic optimization through reinforcement learning

You can improve your recommendations by providing online training techniques, which will retrain your recommender systems after every user-item interaction. By replacing the feedback function with a reward function and adding a reinforcement learning model, we can now make recommendations, take decisions, and optimize choices that optimize the reward function.

This is a fantastic new approach to training recommender models. The Azure Personalizer service offers exactly this functionality, to make and optimize decisions and choices by providing contextual features and a reward function to the user. Azure Personalizer uses contextual bandits, an approach to reinforcement learning that is framed around making decisions or choices between discrete actions in a given context.

Note

Under the hood, Azure Personalizer uses the Vowpal Wabbit (https://github.com/VowpalWabbit/vowpal_wabbit/wiki) learning system from Microsoft Research...
