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.

Summary

In this chapter, we learned when and how to use DL to train an ML model on Azure. We used both compute instance and a GPU cluster from within Azure Machine Learning to train a model using Keras and TensorFlow.

First, we found out that DL works very well on highly structured data with non-obvious relations from the raw input data to the resulting prediction. Good examples are image classification, speech-to-text, or translation. However, we also saw that DL models are parametric models with a large number of parameters and so we often need a large amount of labeled or augmented input data. In contrast to traditional ML approaches, the extra parameters are used to train a fully end-to-end model, also including feature extraction from the raw input data.

Training a CNN using Azure Machine Learning is not difficult. We saw many approaches, from prototyping in Jupyter to augmenting the training data to running the training on a GPU cluster with autoscaling. The difficult part...
