Speak with an AI with some Actual Intelligence

Cleverbot is a chatterbot web application that uses an artificial intelligence (AI) algorithm to have conversations with humans. It was created by British AI scientist Rollo Carpenter. It was preceded by Jabberwacky, a chatbot project that began in 1988 and went online in 1997.[2] In its first decade, Cleverbot held several thousand conversations with Carpenter and his associates. Since launching on the web, the number of conversations held has exceeded 200 million. Besides the web application, Cleverbot is also available as an iOS, Android, and Windows Phone app.[3]

Unlike some other chatterbots, Cleverbot’s responses are not pre-programmed. Instead, it learns from human input: Humans type into the box below the Cleverbot logo and the system finds all keywords or an exact phrase matching the input. After searching through its saved conversations, it responds to the input by finding how a human responded to that input when it was asked, in part or in full, by Cleverbot.[4][5]

I can tell you from experience, chatting with CleverBot can get a bit creepy at times. Some of the responses generated by CleverBot’s computer can seem so human-like.

Also from the CleverBot website:

PLEASE NOTE  –  Cleverbot learns from real people  –  things it says may seem inappropriate  –  use with discretion, and at YOUR OWN RISK

PARENTAL ADVICE  –  Visitors never talk to a human, however convincing it looks  –  the AI knows many topics  –  use ONLY WITH OVERSIGHT

Turing Test 2014

steven_novellaby via NeuroLogica Blog

HAL_9000_225pxThe press is abuzz with the claim that a computer has passed the famous Turing Test for the first time. The University of Reading organized a Turing Test competition, held at the Royal Society in London on Saturday June 7th. The have now announced that a chatbot named Eugene Goostman passed the test by convincing 33% of the judges that it was a human.

The Turing Test, devised by Alan Turing, was proposed as one method for determining if artificial intelligence has been achieved. The idea is – if a computer can convince a human through normal conversation that it is also a human, then it will have achieved some measure of artificial intelligence (AI).

The test, while interesting, is really more of a gimmick, however. It cannot discern whether any particular type of AI has been achieved. The current alleged winner is a good example – a chatbot is simply a software program designed to imitate human conversation. There is no actual intelligence behind the algorithm.

Of course we have to ask what we mean by AI. I think most non-experts think of AI as a self-aware computer, like HAL from 2001. However, the term AI is used by programmers to refer to a variety of expert systems, and potentially any software that uses a knowledge base and a sophisticated algorithm in order to interact adaptively with its user.

Such systems make no attempt to produce computer awareness or even anything that can be considered thinking. They may simulate conversation, even very well, but they are not made to think.

In this way Turing’s test has never been considered a true test of AI self-awareness, or true AI. It really is just a test of how well a computer can simulate human conversation.

Do We Live in the Matrix?


Tests could reveal whether we are part of a giant computer simulation — but the real question is if we want to know…

By Zeeya Merali via DiscoverMagazine.com

In the 1999 sci-fi film classic The Matrix, the protagonist, Neo, is stunned to see people defying the laws of physics, running up walls and vanishing suddenly. These superhuman violations of the rules of the universe are possible because, unbeknownst to him, Neo’s consciousness is embedded in the Matrix, a virtual-reality simulation created by sentient machines.

matrix-red_02_250pxThe action really begins when Neo is given a fateful choice: Take the blue pill and return to his oblivious, virtual existence, or take the red pill to learn the truth about the Matrix and find out “how deep the rabbit hole goes.”

Physicists can now offer us the same choice, the ability to test whether we live in our own virtual Matrix, by studying radiation from space. As fanciful as it sounds, some philosophers have long argued that we’re actually more likely to be artificial intelligences trapped in a fake universe than we are organic minds in the “real” one.

But if that were true, the very laws of physics that allow us to devise such reality-checking technology may have little to do with the fundamental rules that govern the meta-universe inhabited by our simulators. To us, these programmers would be gods, able to twist reality on a whim.

So should we say yes to the offer to take the red pill and learn the truth — or are the implications too disturbing?

Worlds in Our Grasp

The first serious attempt to find the truth about our universe came in 2001, when an effort to calculate the resources needed for a universe-size simulation made the prospect seem impossible.

matrix alternate reality_250pxSeth Lloyd, a quantum-mechanical engineer at MIT, estimated the number of “computer operations” our universe has performed since the Big Bang — basically, every event that has ever happened. To repeat them, and generate a perfect facsimile of reality down to the last atom, would take more energy than the universe has.

“The computer would have to be bigger than the universe, and time would tick more slowly in the program than in reality,” says Lloyd. “So why even bother building it?”

But others soon realized that making an imperfect copy of the universe that’s just good enough to fool its inhabitants would take far less computational power. In such a makeshift cosmos, the fine details of the microscopic world and the farthest stars might only be filled in by the programmers on the rare occasions that people study them with scientific equipment. As soon as no one was looking, they’d simply vanish.

In theory, we’d never detect these disappearing features, however, because each time the simulators noticed we were observing them again, they’d sketch them back in.

That realization makes creating virtual universes eerily possible, even for us.
