Machine learning is a type of Artificial Intelligence that provides a computer with the ability to learn without being explicitly programmed. Machine learning focuses on the development of computer programs that can teach them to grow and change when exposed to new data. Artificial Intelligence is supposed to be the core of Big Data, producing exponential growth in the volume of data used for scientific research. Out of all two most popular machine learning techniques are, supervised and unsupervised learning. Nowadays, learning algorithms such as Bayesian networks and support vector machines is being used more extensively in daily commercial systems.
