Think like human:
One of the dimension of AI is thinking humanly. In 1960, cognitive revolution came into existence which involves information processing psychology. For thinking like human it requires scientific theories of internal activities of brain.
Thinking rationally requires notation and rules of derivation for thoughts. It involves direct line through mathematics and philosophy.
Rational behavior is doing right thing ,one which is expected to maximize goal achievement given the available information. Rational acts do not necessarily involve thinking. For example if glass in your hand is slipping out of grip then you hold it by applying more pressure. we do it without thinking, However achieving perfect rationality in complex environments is not possible.
Act like human:
Creating machines that perform functions that require intelligence. There are a number of capabilities to be incorporated in machines to act like human they include:
- Natural Language Processing
- Automated reasoning
- Machine learning
- Computer vision
- Knowledge representation
In 1950, Alan Turing published a paper in computing machinery and intelligence in which he hypothesized about the possibility of creating machines with intelligence.
In this paper, Alan Turing starts with words “can machines think?”. He proposed a test called Turing test or Imitation game to prove that machines could think.
The Turing test involves the following in his test. He considered a human interrogator who questions and receives responses from both machine and the humans. If he cannot distinguish the difference between both responses then the machine is said to be intelligent.
