Overview of this book

Amazon Redshift Serverless enables organizations to run petabyte-scale cloud data warehouses quickly and in a cost-effective way, enabling data science professionals to efficiently deploy cloud data warehouses and leverage easy-to-use tools to train models and run predictions. This practical guide will help developers and data professionals working with Amazon Redshift data warehouses to put their SQL knowledge to work for training and deploying machine learning models. The book begins by helping you to explore the inner workings of Redshift Serverless as well as the foundations of data analytics and types of data machine learning. With the help of step-by-step explanations of essential concepts and practical examples, you’ll then learn to build your own classification and regression models. As you advance, you’ll find out how to deploy various types of machine learning projects using familiar SQL code, before delving into Redshift ML. In the concluding chapters, you’ll discover best practices for implementing serverless architecture with Redshift. By the end of this book, you’ll be able to configure and deploy Amazon Redshift Serverless, train and deploy machine learning models using Amazon Redshift ML, and run inference queries at scale.

Evaluating model performance

Now we have created the model, let’s dive into the details of its performance.

When building machine learning models, it is very important to understand the model performance. You do this to make sure your model is useful and is not biased to one class over another and to make sure that the model is not under-trained or over-trained, which will mean the model is either not predicting classes correctly or is predicting only some instances and not others.

To address this problem, Redshift ML provides various objectives to measure the performance of the model. It is prudent that we test the model performance with the test dataset that we set aside in the previous section. This section explains how to review the Redshift ML objectives and also validate the model performance with our test data.

Redshift ML uses several objective methods to measure the predictive quality of machine learning models.
