In machine learning, a feature is a property or characteristic of the phenomenon being observed. Features are usually numeric, but structural features such as strings and graphs can be used in pattern recognition. Feature engineering — the process of using domain knowledge to extract features from raw data via data-mining techniques — is often arduous. According to a Forbes survey, data scientists spend 80% of their time on data preparation, and 76% view it as the least enjoyable part of their work. It’s also expensive. Trifecta pegs the collective data prep cost for organizations at $450 billion.
