Feature Store for Machine Learning

By: Jayanth Kumar M J

Overview of this book

Feature store is one of the storage layers in machine learning (ML) operations, where data scientists and ML engineers can store transformed and curated features for ML models. This makes them available for model training, inference (batch and online), and reuse in other ML pipelines. Knowing how to utilize feature stores to their fullest potential can save you a lot of time and effort, and this book will teach you everything you need to know to get started. Feature Store for Machine Learning is for data scientists who want to learn how to use feature stores to share and reuse each other's work and expertise. You’ll be able to implement practices that help in eliminating reprocessing of data, providing model-reproducible capabilities, and reducing duplication of work, thus improving the time to production of the ML model. While this ML book offers some theoretical groundwork for developers who are just getting to grips with feature stores, there's plenty of practical know-how for those ready to put their knowledge to work. With a hands-on approach to implementation and associated methodologies, you'll get up and running in no time. By the end of this book, you’ll have understood why feature stores are essential and how to use them in your ML projects, both on your local system and on the cloud.

Chapter 8: Use Case – Customer Churn Prediction

In the last chapter, we discussed the alternatives to the Feast feature store available on the market. We looked at a few feature store offerings from cloud providers that are part of Machine Learning (ML) platform offerings, namely, SageMaker, Vertex AI, and Databricks. We also looked at a couple of other vendors that offer managed feature stores that can be used with your cloud provider, namely, Tecton and Hopsworks, of which Hopsworks is also open source. To get a feel for a managed feature store, we tried out an exercise on the SageMaker Feature Store and also briefly discussed ML best practices.

In this chapter, we will discuss an end-to-end use case of customer churn using a telecom dataset. We will walk through data cleaning, feature engineering, feature ingestion, model training, deployment, and monitoring. For this exercise, we will use a managed feature store – Amazon SageMaker. The reason for choosing SageMaker...
