The Feast Feature Store and Snowflake
The Providence Athenaeum Library
A feature is a property of a data product that has been reduced into a form to be used for Machine Learning. The feature store contains values transformed via standard methods, such as providing boolean 0 or 1 values for specific properties such as is_blue or is_read or enumerating values like 0 for blue or 1 for red. Additionally, serial numbers can be turned into features by encoding the z-value or creating a mean [1].
Snowflake integrates with the open-source feature store technology Feast [2, 3].
