Have you ever trained an awesome model just to have it break in production because of a null value? At its core a feature store needs to provide reliable features to data scientists to build and productionize models. So how can we avoid garbage in, garbage out situations? Great expectations is the most popular library for data validation, and so the two are a natural fit. In this talk we will touch briefly upon different Python data validation libraries such as Pydantic, Pandera but then dive deeper into Great Expectations’ concepts and how you can leverage them in feature pipelines powering a feature store.
