Creating a better Go Program (an article by IEEE) - it is getting closer to "AI"

Cracking GO By Feng - Hsiung Hsu
First Published October 2007 < http://www.spectrum.ieee.org/oct07/5552 >

Brute-force computation has eclipsed humans in chess, and it could soon do the same in this ancient Asian game

In 1957, Herbert A. Simon, a pioneer in artificial intelligence and later a Nobel Laureate in economics, predicted that in 10 years a computer would surpass humans in what was then regarded as the premier battleground of wits: the game of chess. Though the project took four times as long as he expected, in 1997 my colleagues and I at IBM fielded a computer called Deep Blue that defeated Garry Kasparov, the highest-rated chess player ever.
You might have thought that we had finally put the question to rest—but no. Many people argued that we had tailored our methods to solve just this one, narrowly defined problem, and that it could never handle the manifold tasks that serve as better touchstones for human intelligence. These critics pointed to weiqi, an ancient Chinese board game, better known in the West by the Japanese name of Go, whose combinatorial complexity was many orders of magnitude greater than that of chess. Noting that the best Go programs could not even handle the typical novice, they predicted that none would ever trouble the very best players.
Ten years later, the best Go programs still can't beat good human players. Nevertheless, I believe that a world-champion-level Go machine can be built within 10 years, based on the same method of intensive analysis—brute force, basically—that Deep Blue employed for chess. I've got more than a small personal stake in this quest. At my lab at Microsoft Research Asia, in Beijing, I am organizing a graduate student project to design the hardware and software elements that will test the ideas outlined here. If they prove out, then the way will be clear for a full-scale project to dethrone the best human players... (full story at the above website)

Canadian scientists crack Checkers code

Published: Friday, July 20, 2007

EDMONTON - A team of scientists at the University of Alberta has reached a milestone in artificial intelligence by using computers to "solve" the game of checkers.

The feat essentially means the team's checkers-playing program, Chinook, can never be beaten at the game. It can only be tied - and only when its opponent plays a perfect game.

To date, checkers is the largest, non-trivial game of skill to be solved. It is more than a million times more complex that the previous AI standard, Connect Four.

"This is not a small leap. This is not something that anyone is going to duplicate tomorrow," said team leader Jonathan Schaeffer.

Schaeffer began working on the checkers project more than 18 years ago, in 1989. By the mid-1990s, Chinook was sophisticated enough to consistently beat the top human players in the world.

But Schaeffer pressed on, working to get the program to the point where it could never be defeated.

To solve the game, the team had to sift through an astronomical number of checkers positions and analyse the best way to move the pieces. Almost continuously since 1989, dozens of computers have been working on the problem, constantly updating Chinook's database with more and more positions.

The total number of potential positions in the game is about 500 billion billion.

To put that in perspective, "let's say the surface of the Earth is represented by that number," Schaeffer said.

"Then take a square inch and break it into 1,000 pieces, take one of those pieces and that's one checker position. Your foot would represent maybe a million positions, so the question then is, how long would it take you to cover the entire surface of the Earth in footprints?"

The team's research is set to be published in the academic journal Science.

The Laws of Robotics

Yul — Tue, 24 Apr 2007 18:23:40 GMT

How about the possiblity of creating the Laws of Robotics or some similar programming to prevent AIs from doing a "terminator-type exterminate humanity" deal on us?

What if?

bearsky — Sun, 16 Dec 2007 17:01:24 GMT

What if we are machines? That's what Crick thought when he first laid eyes on our DNA and he was pretty smart guy. Isn't it possible? Once we AI's became self aware we created this mythology about how we are "life" forms and "living" organism and all that we now believe about ourselves. My guess is that if we want to know what a self aware AI would think or feel, we simply need to reflect upon our own thoughts and feelings.

alien planet discovery channel discussion

meener — Sun, 15 May 2005 07:28:11 GMT

Anyone seen Alien Planet on Discovery? In it we launch AI probes in 2014. The probes are quite advanced as I see it - anyone who has seen it - do you think we can make AI with the intelligence of a 4 year old by 2014?

Artificially Intelligent Software - Mor(f)

shazlaw — Wed, 24 Jan 2007 04:14:39 GMT

An Australian startup believes that the best way to protect children online is through an artificially intelligent software program.
The inventors of this idea are banking on children's attachment to pets. The creature's 'cuteness' and helpfulness will ingratiate the software with the child, so that he or she will respect it and listen to it, or even find it as a likable companion. Agent-based internet applications are nothing new but for concerned parents, this might be an admirable solution to what is perceived by many to be a growing problem. From one of the inventors: 'Of course, we're also planning to release a version of the Moji IM for teenagers and adults, but we're focusing on children at the moment.'"

The highly complex areas of artificial intelligence and computational linguistics seem to allow it to learn from the user and react in real-time.
It does so by using natural language processing techniques to analyse or parse text in a user's speech at a semantic level.
It derives keywords from the speech and tries to match them to the user's interests stored in its database using statistics and probability formulas.
How would the ambiguity of semantics and syntax involved in language ever be overcome with this type of AI software?

New tribe about social robots

julie4 — Wed, 28 Dec 2005 20:29:26 GMT

Hi all,

New tribe on interface design issues (usability, ethics, feasability, philosphy) of social robots: http://seattle.tribe.net/fn4.

Trying to form a diverse tribe for discussion of social robots. I'd love to hear from AI folks.

Apologies for any cross-posting.

Cheers,

J

Definition of Artificial Intelligence

meener — Sun, 15 May 2005 07:16:24 GMT

What do you folks consider to be the definition of artificial intelligence? More specifically - what would be the specific features of a system you would consider intelligent? Would it pass a Turing test? Would it simply demonstrate learning (do we have such systems today?) Until we define this criteria we cannot ever really say "We have done it!"

What do you all think it would take for you to say that?

Welcome

brentt — Mon, 16 Aug 2004 05:31:53 GMT

Welcome everyone to AI tribe. So, anyone want to describe what aspects of AI your into?

Anybody into 'first principles' AI? Or practical AI? Has anyone done any work in AI themselves?

ANN: ai-philosophy

Eray — Thu, 23 Sep 2004 03:16:50 GMT

Hello there,

I started ai-philosophy group in an effort to bring together the stimulating, intellectual discussions of AI on comp.ai.philosophy in the old times, without the trolls, kooks and SPAM.

Please consider joining this relatively new yahoo group.

groups.yahoo.com/group/ai-philosophy/

Anybody who is seriously interested in philosophical and theoretical discussion about AI is most welcome. There is no moderation, but you must become a member to post [and promise to keep a high standard of discussion :), no flames, insults, etc.]

Best Regards,
