Introduction to Artificial Intelligence - Old Questions

2.  “System that think like humans” and “System that act like humans” are the part of artificial intelligence. Justify that statement with practical examples.

Artificial intelligence is about designing systems that are as intelligent as humans. It involves trying to understand human thought and an effort to build machines that emulate the human thought process.

System that think like humans

Defⁿ: The exciting new effort to make computers think machines with minds, in the full and literal sense.

E.g. a program that think like humans, i.e. a cognitive modeling approach in which once we have sufficiently precise theory of mind , it become possible to express the theory as computer program.

System that act like humans

Defⁿ:  ”The art of creating machines that perform functions that require when performed by people” .
E.g. Turing Test approach: Which is based on the indistinguishability from undeniably intelligent entities.
           You enter a room which has a computer terminal. You have a fixed period of time to type what you want into the terminal, and study the replies. At the other end of the line is either a human being or a computer system.                   
           If it is a computer system, and at the end of the period you cannot reliably determine whether it is a system or a human, then the system is deemed to be intelligent.
