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.

Will Durant
William James “Will“ Durant (/dəˈrænt/; November 5, 1885 – November 7, 1981) was an American writer, historian, and philosopher. He became best known for his work The Story of Civilization, 11 volumes written in collaboration with his wife, Ariel Durant, and published between 1935 and 1975. He was earlier noted for The Story of Philosophy (1926), described as “a groundbreaking work that helped to popularize philosophy”.
He conceived of philosophy as total perspective or seeing things sub specie totius (a phrase inspired by Spinoza‘s sub specie aeternitatis). He sought to unify and humanize the great body of historical knowledge, which had grown voluminous and become fragmented into esoteric specialties, and to vitalize it for contemporary application.
The Durants were awarded the Pulitzer Prize for General Nonfiction in 1968 and the Presidential Medal of Freedom in 1977.

James Watson
James Dewey Watson (born April 6, 1928) is an American molecular biologist, geneticistand zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. Watson, Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine “for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material”.
Converse
Switching the hypothesis and conclusion of a conditional statement. For example, the converse of “If it is raining then the grass is wet” is “If the grass is wet then it is raining.”
Note: As in the example, a proposition may be true but have a false converse.
Luca Pacioli

Fra Luca Bartolomeo de Pacioli (sometimes Paccioli or Paciolo; c. 1447 – 19 June 1517) was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and an early contributor to the field now known as accounting. He is referred to as “The Father of Accounting and Bookkeeping” in Europe and he was the first person to publish a work on the double-entry system of book-keeping on the continent.[4] He was also called Luca di Borgo after his birthplace, Borgo Sansepolcro, Tuscany.
