What is Artificial Intelligence?

Intelligence is:
– the ability to reason
– the ability to understand
– the ability to create
– the ability to Learn from experience
– the ability to plan and execute complex tasks

Artificial intelligence can be referred as the ability given to machine to perform tasks normally associated with human intelligence.
According to Barr and Feigenbaum:
―Artificial Intelligence is the part of computer science concerned with designing intelligence computer systems, that is, systems that exhibit the characteristics we associate with intelligence in human behavior.‖
Different definitions of AI are given by different books/writers. These definitions can be divided into two dimensions.
Top dimension is concerned with thought processes and reasoning, where as bottom dimension addresses the behavior.The definition on the left measures the success in terms of fidelity of human performance, whereas definitions on the right measure an ideal concept of intelligence, which is called rationality.
Human-centered approaches must be an empirical science, involving hypothesis and experimental confirmation. A rationalist approach involves a combination of mathematics and engineering.
