A test of a machine's ability to exhibit intelligent behavior indistinguishable from that of a human.
More about Turing Test
Turing Test was proposed by the British mathematician and computer scientist Alan Turing in 1950. The test involves a human evaluator who engages in natural language conversations with a machine and a human without knowing which is which. If the evaluator cannot reliably distinguish the machine from the human based on the conversation, the machine is said to have passed the test. The Turing Test is considered a significant milestone in the study of artificial intelligence, gauging a machine's capability to exhibit human-like intelligence.
However, while iconic, many AI researchers believe that the Turing Test isn't the sole or definitive measure of machine intelligence.
