Overview of this book

Data scientists working on productionizing machine learning (ML) workloads face a breadth of challenges at every step owing to the countless factors involved in getting ML models deployed and running. This book offers solutions to common issues, detailed explanations of essential concepts, and step-by-step instructions to productionize ML workloads using the Azure Machine Learning service. You’ll see how data scientists and ML engineers working with Microsoft Azure can train and deploy ML models at scale by putting their knowledge to work with this practical guide. Throughout the book, you’ll learn how to train, register, and productionize ML models by making use of the power of the Azure Machine Learning service. You’ll get to grips with scoring models in real time and batch, explaining models to earn business trust, mitigating model bias, and developing solutions using an MLOps framework. By the end of this Azure Machine Learning book, you’ll be ready to build and deploy end-to-end ML solutions into a production system using the Azure Machine Learning service for real-time scenarios.

Featurization concepts in AML

In order to provide the best model, regardless of whether AutoML is being leveraged, an important step in model creation is the engineering features. AutoML in AMLS will default to leverage featurization. This can be disabled in the UI as well as the SDK if the feature engineering step has already been accomplished. These featurization transformations on your dataset can not only be enabled or disabled but they can also be customized or excluded from specific columns. There are several featurization steps applied to your dataset based on the type of column, and the column’s data type.

During training, AutoML leverages scaling or normalization to ensure model performance. AutoML leverages a variety of techniques, including scaling to unit variance, scaling by quantile range, scaling by the maximum absolute value, scaling by a column’s minimum and maximum, by applying Principle Component Analysis (PCA) for dimensionality reduction, Singular...
