Feature selection

Feature selection: The process of selecting a feature subset to simplify models and reduce noise, cost or redundancy. Filters, wrappers and embedded methods use different criteria. Selection belongs inside validation to avoid target contamination of the test. This perspective connects the definition with practical behaviour in artificial intelligence systems.
