Keeping tabs on Skynet
(PhysOrg.com) -- In line with the predictions of science fiction, computers are getting smarter. Now, scientists are on the way to devising a test to ascertain how close Artificial Intelligence (AI) is coming to matching wits with us, and if its drawing ahead.
Associate Professor David Dowe of Monash Universitys Faculty of Information Technology, together with Dr Jose Hernandez-Orallo from Universitat Politecnica de Valencia in Spain have developed and conducted initial trials of a prototype Anytime Universal Intelligence test designed to gauge and compare the intelligence of humans, animals, machines, and, in principle, anything.
Both humans and an AI program known as Q-Learning undertook different versions of the test, with considerable work on adapting the interface necessary before animals can be tested. Despite not being a sophisticated program, Q-Learning scored competitively compared with the human participants.
Associate Professor Dowe said the ambiguity of the initial test results indicates the complexity of moving to a broader understanding of intelligence than the traditional method of using human intellect as the yardstick a development necessary to determine if, or perhaps when, AI outstrips humans.
We are using a mathematically-based definition of intelligence which is based, in simple terms, on the ability to detect patterns of various degrees of complexity. In the future, the test should adapt to the user becoming more complex if the user is scoring well, and more simple if the user is struggling, said Associate Professor Dowe.
Clearly, we have very specialised indications of the intelligence of computer programs, when theyre beating humans at activities like chess and the game show Jeopardy. Were trying to establish a broader indication.
With further research, this type of testing could help not only in assessing the progress of AI, but in driving development.
Inspired partly by Foundation Chair in Computer Science at Monash University, Professor Chris Wallaces research on Minimum Message Length, a theory of machine learning and statistics, Associate Professor Dowe has been working on alternatives to traditional measures of intelligence since the late 1990s. His projects have included the development of a relatively simple computer program that regularly scored close to the purported human average of 100 on standard IQ tests.
More information: Dr Hernandez-Orallo, recently presented the results of the testing at the Artificial General Intelligence Conference, hosted by Google, California.

But even such hypothetical AIs don't go from "dumb as rocks" to "supersmart as to be aware of such tests and figuring out a way to skew them" just like that. So you should be able to catch them en route IF (and that is a big 'if') the test is well designed.
One might speculate that there may be more than the 'biological' kind of intelligence we are used to (particularly since the attempts at AI use different mechanisms than biological brains do) - so I'm not at all convinced that there is a one-size-fits-all kind of test for this.

In seriousness though. I'm not sure if we can make a truly concious AI, but it is pretty unlikely in binary. It will require at least the neural logic type circuits that IBM developed (I don't remember the exact name of them) and probably a true quantum computing component as well.
But seeing as we are not positive what makes up sentience in the first place, i could be barking up a tree over in alpha centauri as far as i know.

No. They designed a chip with transistors that operate in a 'neural network' rather than more linear process chips use today. These new chips would be more of a branching algorithm, that would have more options than 3 at any juncture.

Fuzzy logic is an integral piece of any good AI algorithm, but I think the potential was way overhyped in its day. It was a step in a direction, not a leap.
Emotions are an interesting concept. Most of our 'biological' emotions are based upon a world of factors that have limited applicability to our theoretical sentient computer. I would argue that emotion is largely a product of our evolution, helping us work together, preserving the species, etc. A computer would not have that evolutionary hangup.
If computers do develop true emotions, they could very well be so alien to us that we would not recognize them, or perhaps just a few that are somewhat analagous to our own.

Does not mean trying to conquer the world (That's territorial and mating instinct witch computers dont need).
Many people confuse intelligence with goals. We, humans have many genetically imposed goals, which make us slaves of information on a DNA molecule. Computers dont need such restrictions.
If AI does ever go Skynet, we should be blamed for putting such foolish goals on it.

Huh?
Maybe the best algorithm on the best computer.
in case you didn't know this, you can google it. Really good chess players still have a hard time finding a chess engine that challenges them. Winboard is, I think, one of the top engines out there.
I don't even play chess much at all any more, and I gotta say, I can't beat windows "Chess Titans" on max difficulty, but I have beaten it on 8th difficulty at least one time.
The fact that even chess, a relatively simple purely mathematical game, requires a super computer to beat an expert human should tell you where computers stand.

Even among humans, skill, "talent" and experience gaps are enormous for different activities.
The reality is in many games the a.i. isn't even worked on, or is left intentionally "dumb" for one reason or another. There's a couple reasons.
For "simple" games like RPGs, if the enemy A.I. always took the optimal action (such as using buffs, debuffs, and concentrated fire appropriately,) then the player probably would not be able to win some boss fights and random encounters.
For complex games like Starcraft, writing an A.I. capable of playing at the professional level would may as well be making a true general purpose a.i. You'd literally need an a.i. like Commander Data in Star Trek in order to consistently beat the top players.
Humans are able to innovate and spot tricks and glitches that pure game stats don't quantify well

Back whenever I played "Mask of the Betrayer", the expansion to Neverwinter Nights 2, I did a LOW LEVEL walkthrough, in which I never took my level ups and I played a Wizard on max difficulty, which is where you deal half damage MAX to enemies and they deal half damage MINIMUM to you, i.e. top cap of half vs bottom cap of half, etc.
The game designers claimed they designed the game to minimize micro, and make it purely about enforcing the D&D game mechanics.
They lied.
I was able to walk through a level 30 campaign using a level 17 characer, on DOUBLE the core rules difficulty, and take absolutely no damage, ever, from any enemies.
Later, I was able to use a no micro/low micro character and do the same feat again at around level 20 or 21, I forget.
The point I'm getting at is not to brag, but to show how inferior the ai really is, and how inferior developers are at their own game

That was true maybe 5-10 years ago, however today not so much. It's not the computing power that has increased that has made the biggest difference, it's improvements to the software. Look at the final entry on this wikipedia page: http://en.wikiped..._matches
So while computers aren't winning every single match against the best chess players in the world, they are certainly winning a lot more than they are losing.

The game mechanics in NWN2, and especially the expansions, were too good and the ai were not smart enough to challenge a skilled player, even when the difficulty is set so high that the game engine cheats for the enemies.
The other thing I'd say is that as alluded to earlier, the game designers themselves showed a fundamental lack of understanding of their own game's mechanics. The enemy ai were not even remotely designed to fight against the expert level character builds I came up with or that other players came up with, EVEN after perfect low levels "no XP gain" self restrictions. They also were not designed to fight against a player who micro-managed or who used "real" tactics, which was a total and pointless mistake. The attempts to prevent micromanagement and tactics actually encouraged it and broke the mechanics.

Things like evolving computer viruses are part of the equation in my mind, they are like SkyNets eyes, they can store, distribute and receive info on a "cloud" basis. Meaning we would have an extremely hard time getting the full picture until it's WAY too late.
It's not just viruses it's also the antivirus industry developing more advanced detection heuristics and algorithms which would be Skynet's brains and reasoning centers.
My worry is some anarchist virus writer making a virus that hijacks your antivirus in order to develop better ways of hiding, multiplying and recognizing itself.
It's like we already have a skeleton and all we need to do is breathe life into it.
When a computer program is developed that can decompress into a few quadrillion bits from only a billion or so bits and still have coherent algorithmic control of its compression functions we will start to see it grow uncontrollably.

Machine learning that is done now is extremely specialized to a single framework or a single sub-set of classes, whether it's game ais, weather models, or expert machines, or financial models, etc.
Even now, the main advantage an ai has is "memory", not actual problem solving ability.
consider this, if you are counting the occurences of several events and so keeping track of several tallies, you probably use a piece of paper and some marks to count, because you can't remember it all. But the paper "remembers" just like a computer or a photograph "remembers". A chess ai is similar, in that the real reason it is so good is it can try all possibilities and it has a perfect memory it need not "solve" anything, as it can try all possibilities and then take the winning possibility..

If a human was allowed to take out a piece of paper and sit there and systematically write down all possible moves and rate them, so that they don't forget what they've done in the process of planning their move, etc, then they'd be at least equal to the computer.

Watson on jeopardy put down the percentages of his decisions and basically flipped a coin with them. This is essentially the same thing a conflicted person is doing. You aren't sure what you want, eventually you just go with something. That or sit there bored for hours, eventually it comes down to a mental coin flip if you can't make the choice directly on merit.

Gaming AI's are dummed down on purpose to enable human players to win.
Game wouldn't be interesting if you had no chance of winning, nooone would buy it. Try the "Hard" settings on some games to see what I mena.
That's said, Gaming AI deal with pre-set world, familiar to them, where General AI is dealing with totally unfamiliar world and need to have ability to learn.
We are not there yet. Its only a matter of time.

Interestingly enough, it would be possible with current technology to facilitate that. We have graphics cards capable of rendering realistic mouth movements on the fly, and there's both voice recognition and synthesis hardware that could handle the job with a few refinements. Place that hardware on a sound card that translates the spoken words to text, which is fed to the game, and the game sends the reply with phonetic and infelction cues to the card, which already has the voice profile loaded for that character, and there's the voice response, while some sort of
