Not to be confused with Feature (computer vision).
In machine learning and pattern recognition, a feature is an individual measurable property or characteristic of a phenomenon.[1] Choosing informative, discriminating and independent features is a crucial element of effective algorithms in pattern recognition, classification and regression.
