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.

Working with tree-based ensemble classifiers

Supervised tree-based ensemble classification and regression techniques have proven very successful in many practical real-world applications in recent years. Hence, they are widely used today in various applications, including fraud detection, recommendation engines, tagging engines, and many more. All your favorite mobile and desktop operating systems, Office programs, and audio or video streaming services make heavy use of them every day.

Therefore, in this section, we will dive into the main reasons for their popularity and performance, both for training and scoring. If you are an expert on traditional ML algorithms and know the difference between boosting and bagging, you might as well jump right to the next section, Training an ensemble classifier model using LightGBM, where we put the theory into practice.

We will first look at decision trees, a very simple technique that is decades old. We encourage you to follow along even...
