Artificial Intelligence is often used to describe machines or computers that mimic cognitive functions that human associate with the human mind for learning and problem solving. Analytical Artificial Intelligence has only characteristics generating cognitive representation of the world and using learning based on past experience to inform future decisions. Many AI algorithms are capable of learning from data; they can enhance themselves by learning new rules, strategies or rules that have worked in the past. Learning without any kind of supervision requires an ability to identify patterns in inputs. Machine perception deals with the capability to sensor inputs. Computer vision is the power to analyze visual inputs with a few such problems such as facial, object and gesture recognition. Artificial intelligence is frequently applied to the project of developing systems. Some programs have achieved the level of performance of human experts and professionals in performing certain specific tasks. Artificial intelligence is found in applications as diverse as medical diagnosis, computer search engines, and voice or handwriting recognition. Problem solving methods divides into special purpose and general purpose. A general purpose method is applicable to wide range variety of problems. Artificial intelligence mostly used in computer vision. Machines can react like humans. Artificial intelligence is also a part of machine learning. Artificial intelligence is a science and technology based on some innovative fields such as Electrical, Computer, and Engineering etc. AI is in the development of computer functions associated with human intelligence, reasoning and problem solving. Natural language processing allows humans to interact with computers without needing any depth knowledge. Programming computers to understand natural languages has proved more difficult. It also helps to implement voice recognition systems that can convert spoken sounds into written words. In real world, the artificial intelligence has some unknown properties such as volume is very large, next to unimaginable, not well organized or formatted. It keeps changing constantly. Artificial intelligence is a manner to organize and use knowledge efficiently very easy to modify to correct errors. It is very useful in many situations.
