Machine Learning : What is Machine Learning ?

Machine learning is a method used to make complex models and algorithms by analysing huge amount of data, that lend themselves to prediction, making use of computers. It has strong relation with mathematics. Which optimizes and delivers methods, theory and application domains to this field. It is sometimes conflated with data mining, whereas Data Mining is process where intelligent methods are applied to extract data patterns. Tom M. Mitchell provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T, as measured by P, improves with experience E. This definition of the tasks in which machine learning is concerned offers a fundamentally operational definition rather than defining the field in cognitive terms.
