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 7: Feast Alternatives and ML Best Practices

In the last chapter, we discussed how to use Amazon Managed Workflows with Apache Airflow for orchestration and productionizing online and batch models with Feast. So far in this book, we have been discussing one feature store – Feast. However, there are a bunch of feature stores available on the market today. In this chapter, we will look at a few of them and discuss how they are different from Feast and the advantages or disadvantages of using them over Feast.

In this chapter, we will try out one other feature store, specifically Amazon SageMaker. We will take the same feature set that we generated while building the customer lifetime value (LTV) model and ingest it into SageMaker Feature Store and also run a couple of queries. The reason for choosing AWS over other feature stores such as Tecton, Hopworks, and H2O.ai is the easy access to the trial version. However, choosing the right feature store for you depends on...
