The Turing Test, proposed by British mathematician and computer scientist Alan Turing in 1950, is a measure of a machine's ability to exhibit intelligent behavior indistinguishable from that of a human. In the test, a human evaluator interacts with a machine and a human through text-based conversation, without knowing which is which. If the evaluator cannot reliably distinguish the machine from the human, the machine is said to have passed the test, demonstrating a form of artificial intelligence. The test focuses on the machine's ability to generate human-like responses and mimic human conversational abilities.
