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.

Preprocessing and feature engineering with Azure Machine Learning DataPrep

In this section, we will dive deeper into the preprocessing and feature extraction process using Azure Machine Learning. We will first access and extract data with different data formats from different storage systems, such as text data and CSV data from blob storage, and tabular data from relational database systems.

Then, we will take a look at common data transformation techniques using Azure Machine Learning DataPrep, a Python library to build transformations on top of datasets directly in Azure Machine Learning. You will also learn common techniques of how to filter columns, split columns through expressions, fix missing values, convert data types, and even how to derive transformations through examples.

Finally, we will write the data back into data storage where it can be registered as a cleaned dataset in Azure Machine Learning. By doing this you can implement fully enterprise-grade ETL and data...
