Artificial Intelligence

November 29, 2017

Definition - Artificial Intelligence is the science and engineering of making intelligence machines, especially intelligent computer programs ( John McCarthy ) - Artificial Intelligence is a way of making a computer-controlled robot, or a software think intelligently, in the similar manner the intelligent humans think. Philosophy of AI - While exploiting the power of the computer systems, the curiosity of human, lead him to wonder, "Can a machine think and behave like humans do?" Thus, the development of AI started with the intention of creating similar intelligence in machines that we find and regard high in humans. Goal of AI To Create Expert Systems: The systems which exhibit intelligent behavior, learn, demonstrate, explain, and advice its users. To Implement Human Intelligence in Machines: Creating systems that understand, think, learn, and behave like humans.
