We are going to commence our new tutorial series about Machine Learning. We will use python as programming language for this tutorial series. This article gives a brief introduction to Machine Learning. 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." Machine Learning models consists algorithms that can learn and make predictions from data.Machine Learning has been evolved from prediction making and computational learning theory in artificial intelligence.It helps computers to learn and perform a certain task based on past experience.These models can be based on following: In this article we saw a brief introduction to Machine Learning and in next article we will see how to install Anaconda.
