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.

Collaborative filtering – a rating-based recommender system

By recommending only similar items or items from similar users, your users might get bored of the recommendations provided due to the lack of diversity and variety. Once a user starts interacting with a service (for example, watching videos on YouTube, reading and liking posts on Facebook, or rating movies on Netflix), we want to provide them with great personalized recommendations and relevant content to keep them happy and engaged. A great way to do so is to provide a good mix of similar content and new content to explore and discover.

Collaborative filtering is a popular approach for providing such diverse recommendations by comparing user-item interactions, finding other users who interact with similar items, and recommending items that those users also interacted with. It's almost as if you were to build many custom stereotypes and recommend other items consumed from by same stereotype. Figure 13.6 illustrates...
