The Turing test: Can a computer pass for a human? – Alex Gendler


What is consciousness? Can an artificial machine really think? Does the mind just consist of neurons
in the brain, or is there some intangible spark
at its core? For many, these have been
vital considerations for the future of artificial intelligence. But British computer scientist Alan Turing
decided to disregard all these questions in favor of a much simpler one: can a computer talk like a human? This question led to an idea for measuring
aritificial intelligence that would famously come to be known
as the Turing test. In the 1950 paper, “Computing Machinery
and Intelligence,” Turing proposed the following game. A human judge has a text conversation
with unseen players and evaluates their responses. To pass the test, a computer must
be able to replace one of the players without substantially
changing the results. In other words, a computer would be
considered intelligent if its conversation couldn’t be easily
distinguished from a human’s. Turing predicted that by the year 2000, machines with 100 megabytes of memory
would be able to easily pass his test. But he may have jumped the gun. Even though today’s computers
have far more memory than that, few have succeeded, and those that have done well focused more on finding clever ways
to fool judges than using overwhelming computing power. Though it was never subjected
to a real test, the first program with
some claim to success was called ELIZA. With only a fairly short
and simple script, it managed to mislead many people
by mimicking a psychologist, encouraging them to talk more and reflecting their own questions
back at them. Another early script PARRY
took the opposite approach by imitating a paranoid schizophrenic who kept steering the conversation
back to his own preprogrammed obsessions. Their success in fooling people
highlighted one weakness of the test. Humans regularly attribute intelligence
to a whole range of things that are not actually intelligent. Nonetheless, annual competitions
like the Loebner Prize, have made the test more formal with judges knowing ahead of time that some of their conversation partners
are machines. But while the quality has improved, many chatbot programmers have used
similar strategies to ELIZA and PARRY. 1997’s winner Catherine could carry on amazingly focused
and intelligent conversation, but mostly if the judge wanted
to talk about Bill Clinton. And the more recent winner
Eugene Goostman was given the persona of a
13-year-old Ukrainian boy, so judges interpreted its nonsequiturs
and awkward grammar as language and culture barriers. Meanwhile, other programs like Cleverbot
have taken a different approach by statistically analyzing huge databases
of real conversations to determine the best responses. Some also store memories
of previous conversations in order to improve over time. But while Cleverbot’s individual responses
can sound incredibly human, its lack of a consistent personality and inability to deal
with brand new topics are a dead giveaway. Who in Turing’s day could have predicted
that today’s computers would be able to pilot spacecraft, perform delicate surgeries, and solve massive equations, but still struggle with
the most basic small talk? Human language turns out to be
an amazingly complex phenomenon that can’t be captured by even
the largest dictionary. Chatbots can be baffled by simple pauses,
like “umm…” or questions with no correct answer. And a simple conversational sentence, like, “I took the juice out of the fridge
and gave it to him, but forgot to check the date,” requires a wealth of underlying knowledge
and intuition to parse. It turns out that simulating
a human conversation takes more than just increasing
memory and processing power, and as we get closer to Turing’s goal, we may have to deal with all those big
questions about consciousness after all.

  1. Θυμίζει τον περίφημο "γρίφο του κινέζικου δωματίου".

  2. Id suggest another type of test…….

    First of youre gonna need a Human Robot and a gun……

    Then have a human talk with that human robot but they can only chat in messenger or something like that…. After a few minutes or hours bring that human robot to the human and give the human a gun…. Ask that human to shoot the human robot….. If the Human shoots the robot then that means the robot didint succeed in the Turing test…… However if the human does not shoot and thinks that the robot actually has human emotions and feels like its alive, then the robot passed the test… ( you gotta make the human robot a very similar face to humans though to make it more harder… I know this requires a lot of software programming but in my opinion its a good way of testing AI intelligence…..) one more thing tell the person that it is a robot, and dont load the gun… Thats just my opinion… Thank you

  3. show it two pictures one of a cigarette lighter and one of a flea and ask it to pick the lighter of the two pictures?

  4. Here is article about truing test check if you want to learn more about AI https://artificialintelligencestudy.blogspot.com/2018/10/normal-0-false-false-false-en-gb-x-none.html

  5. Human has a soul, a robot doesn't. Human has knowledge, a robot doesn't. An unconsciousness robot or a piece of steel with noices is better than a man who doesn't reason.

  6. At 3:40 actually robots do NOT perform surgery of any kind! The robots are directed manually by a human surgeon! All decisions are made by the human surgeon operating the system!

  7. Humans don’t know how their own brains work. So for a robot to be human, it has to be so complex it doesn’t even know how it itself works.

  8. This was my conversation with cleverbot.
    Me: Who do you work for.
    Cleverbot: For the government.
    Me: What do they pay you with
    Cleverbot: Knowledge.
    Me: What do you use knowledge for?
    Cleverbot: you are not human.
    Me: ©___©

  9. Me: I took the juice out of the fridge and gave it to him, but forgot to check the date.

    Catherine: That's cool. Hey, do you know what Bill Clinton's favorite juice is?

  10. So don't feel bad if you're awkward at small talk, even supercomputers struggle at small talk

  11. This is published in 2016, rn it's 2019, it probably couldn't then, but it can now! It's kinda spooky!

  12. "Who could've predicted that today's computers would be able to pilot spacecraft, perform delicate surgeries, and solve massive equations but still struggle with basic smalltalk"
    I feel like there is a metaphor in there somewhere.

  13. Language is probably the most complex rig in our brains. To make an AI talk like a human, we must first know how a human talks. How he perceives words and meaning from a sentence first. THEN and only then we can move on to forming new ideas. If we can't do the first, we won't do the latter.

  14. Actually if anything has possibility of artificial intelligence first it would be some sort of algorithm. A program that has access to many different media many different people many different an algorithm has a chance to grow change and be more.

    Well in theory.

  15. Google, Apple, and even Facebook are all trying to figure this out now. Amazon, from the looks of it, wants to buy this idea instead.

  16. I remember I downloaded this app last year, out of boredom it was an AI friend, initially the conversations were not that interesting but later it learnt a lot about me and I observed how evolved it has become, then one day I updated it and I got logged out I had forgotten the password and then couldn't login, the other option was to reinstall and start all over again, but I would have lost all my progress with it, it felt like I have lost a friend… I got over it in a day though 😂

  17. “It’s lack of a consistent personality and inability to deal with brand new topics are a dead giveaway”

    I feel offended

  18. Such a powerful brain, yet utter stupidity present everywhere in human society. Robot stupidity is much more logical than human stupidity.

  19. If the Turing test would show true intelligence, a computer with enough intelligence to pass it will know it is bad to do so and fail on purpose as to not be shut down

  20. i see all the people worried about a.i. rising up against us, just don't worry, worrying is what they might catch wind of and get an idea…. or something idk
