What is a feature?

Feature extraction is the process of reducing the dimensionality of data to more efficiently represent its values. A feature, or column, represents a measurable piece of data that can be used for analysis: Name, Age, Sex, Fare, and so on. Features are also sometimes referred to as “variables” or “attributes.” This technique was pioneered by data scientists who needed to prepare data for demanding machine learning and AI workloads.
