Machine learning is the subfield of computer science that gives computers the ability to learn without being explicitly programmed - Arthur Samuel , 1959 Evolved from the study of pattern recognition and computational learning theory in artificial intelligence , machine learning explores the study and construction of algorithms that can learn from and make predictions on data Machine learning is the study of computer algorithms that improve automatically through experience - Tom Mitchell In 2006, the online movie company Netflix held the first " Netflix Prize " competition to find a program to better predict user preferences and improve the accuracy on its existing Cinematch movie recommendation algorithm by at least 10%.
