For questions about the concept of intelligence, not restricted to Artificial Intelligence, but applied also to intelligence in nature, quantification of intelligence (problem solving strength), and qualification of intelligence (terminology and the range of meanings).
Intelligence has been defined in many different ways including the capacity for logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, and problem solving. It can be more generally described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context.
Intelligence is most widely studied in humans but has also been observed in both non-human animals and in plants. Intelligence in machines is called artificial intelligence, which is commonly implemented in computer systems using program software.
