Mastering Azure Machine Learning - Second Edition

By: Christoph Körner, Marcel Alsdorf

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.

Remembering the importance of data

Many algorithmic problems for predictions and model fitting are hard to model, compute, and optimize using classic optimization algorithms or complex heuristics. Supervised machine learning provides a powerful new way to solve the most complex problems using optimization and a ton of labeled training data.

Some may think you just should throw a metric ton of data at a model. Imagine that you have thousands of pictures of the same bird from every possible angle. A trained model based on those pictures would probably not be very predictive for classifying different bird families.

Choosing the Right Data Samples for Your Model

A trained model will increase in quality when it's using highly distinct data samples and data samples that are useful in the context of what your model should predict.

So, when you're working with ML algorithms, you need to remember that models are powered by the training data you provide them with, as well...
