The landscape of artificial intelligence (AI) is dominated by a question that was introduced by Alan Turing, a pioneer in the field. This fundamental question revolves around the determination of intelligence in machines. But how does one even quantify intelligence? Are there varying degrees of intelligence among humans and animals? These form the bedrock of our discussion.
Unpacking Intelligence: A Matter of Perception?
Identifying intelligence is subjective and can vary greatly. It isn’t necessarily a matter of a straightforward yes or no. For instance, we can find intelligent individuals among both humans and animals. However, when it comes to machine intelligence, the waters become murky.
To streamline this, Turing aimed at defining intelligence in operational terms. He endeavored to delineate functionality (what an entity does) from its implementation (how it is built). The result was the creation of a theoretical model of evaluation now known as the Turing Test.
What is the Turing Test?
To comprehend the Turing Test, we first need to grasp the concept of imitation games that Turing proposed. These are games where an entity tries to impersonate another. The goal of these games is to understand and evaluate the imitation’s success in fooling an interrogator.
The Initial Imitation Game
In the primary game, an interrogator is in a room, divided by a curtain. On the other side of the curtain is another individual. The interrogator’s task is to determine if the hidden individual is a man or a woman by asking a series of questions. These questions are answered via a computer to eliminate vocal cues, putting emphasis on the content of responses. The success of the imitation game is determined by the hidden individual’s ability to deceive the interrogator.
This format was inspired by a popular game of Turing’s era and may have even driven his development of the Turing Test.
The Evolving Turing Test
Turing’s concept continues to evolve and impact the field of AI today. Interesting updates on this topic can be found in this Futurism article and a feature on The Conversation.
One notable supporter of the original Turing Test was Erich Fromm, a respected 20th-century sociologist and psychoanalyst. He believed in gender equality but acknowledged differences in knowledge and behavior among genders. Fromm’s stance is relevant in understanding Turing’s approach to intelligence—diverse ways of thinking should be recognized and embraced.
The Turing Test for AI
The second imitation game, more relevant to AI, involves a computer in place of a human behind the curtain. Here, the computer plays the role of the ‘deceiver,’ similar to the male role in the initial game. The interrogator’s goal remains the same – to discern if they’re communicating with a person or a machine based on the responses. If the computer successfully tricks the interrogator, it passes the Turing Test and is deemed intelligent.
