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.

Summary

In this chapter, we set out with the aim of trying out a use case, namely telecom customer churn prediction using a dataset available from Kaggle. For this use case, we used a managed SageMaker Feature Store, which was introduced in the last chapter. In the exercise, we went through the different stages of ML, such as data processing, feature engineering, model training, and model prediction. We also looked at a feature monitoring and model monitoring example. The aim of this chapter was not model building but to showcase how to use a managed feature store for model building and the opportunities it opens for monitoring. To learn more about feature stores, the apply conference (https://www.applyconf.com/) and feature store forum (https://www.featurestore.org/) are good resources. To stay updated with new developments in ML and how other firms are solving similar problems, there are a few interesting podcasts, such as TWIML AI (https://twimlai.com/) and Data Skeptic (https...
