Feature (machine learning)

Jovan Stosic June 17, 2019

In machine learning and pattern recognition, a feature is an individual measurable property or characteristic of a phenomenon being observed.[1] 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.

Col legno – violin bowing technique

Jovan Stosic June 16, 2019

Col legno – Occasionally the strings are struck with the stick of the bow (“with the wood.”) This gives a muted percussive sound, and is most effective when employed by a full orchestral violin section. The eerie quality of a violin section playing col legno is exploited in some symphonic pieces, notably the “witches’ dance” of the last movement of Berlioz’ Symphonie Fantastique as well as Frederic Chopin’s Warsaw-era Piano Concerto No. 2, which predates it.
