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.

Chapter 5: Performing Data Analysis and Visualization

In the previous chapter, we learned how to bring our datasets to the cloud, define data stores in the Azure Machine Learning workspace to access them, and register datasets in the Azure Machine Learning dataset registry to have a good basis to start data preprocessing from. In this chapter, we will learn how to explore this raw data.

First, you will learn about techniques that can help you explore tabular and file datasets. We will also talk about how to handle missing values, how to cross-correlate features to understand statistical connections between them, and how to bring domain knowledge to this process to improve our understanding of the context and the quality of our data cleansing. In addition, we will learn how to use ML algorithms not for training but for exploring our datasets.

After that, we will apply these methods to a real-life dataset while learning how to work with pandas DataFrames and how to visualize the...
