Welcome to popular Wiki of the Day where we read the summary of a popular Wikipedia page every day.
With 991,353 views on Wednesday, 31 October 2018 our article of the day is Feature (machine learning).
In machine learning and pattern recognition, a feature is an individual measurable property or characteristic of a phenomenon being observed. Choosing informative, discriminating and independent features is a crucial step for effective algorithms in pattern recognition, classification and regression. Features are usually numeric, but structural features such as strings and graphs are used in syntactic pattern recognition.
The concept of "feature" is related to that of explanatory variable used in statistical techniques such as linear regression.
