synthetic intelligence
Science fiction has built up the idea of artificial brain for years. Giving machines brain often spells the end of mankind as they then rise up against their creators and violently free themselves from oppression. There are cautionary tales such as in the film “Spider Man 2” in which the robotic arms of Dr. Octavius start controlling his brain thus forcing him to achieve actions of benefit to them. I’ve never de facto had an interest in artificial brain until recently when I started studying the very basics at university. The only Ai Science Fiction that’s ever de facto concerned me was ‘Blade Runner’ and its novel, ‘Do Androids Dream of galvanic Sheep?’ written by Philip K. Dick. The subtext of the story deals with Ai becoming self-aware but still unaware of its true nature, a view that concerned me greatly. Real Ai is quite keen and in many ways entirely distinct to what I expected.
To start with, what exactly is Ai? http://www.dictionary.com defines it as follows:
Hdtv
1. The capability of a computer or other motor to achieve those activities that are usually view to need intelligence.
2. The field of computer science concerned with the amelioration of machines having this ability.
If you take a look at this you may observation that the field of Ai is de facto far broader than many population give it prestige for. Even the Google search motor can be said to integrate some of the investigate done in Ai. The definition of Ai and brain itself sometimes varies but it’s probably safe to say that a uncomplicated explanation is that if a motor exhibits a part of brain in some area it can be called Ai.
The Ai of movies is usually entirely self aware, emotive, and for all intents and purposes ‘alive’. It is capable of learning, reasoning, explaining and deceiving. The Ai I’ve experienced (and this is very basic, scratching only the exterior of the depth of studies into Ai) is far more specialized, focusing on just one aspect of a qoute that could potentially be much larger. There are assorted areas of investigate being carried out into creating the humanoid machines of science fiction, but as yet most are still restricted to the realms of the imagination. One very impressive piece of technology is the Honda Asimo project. This project has created a humanoid robot with some mighty features. I’m not entirely sure if there’s de facto a practical use for this (I think they’re just trying to construe their funding with the applications mentioned on the website) but it scores points for being one of the coolest uses of technology I’ve ever seen. You can see some videos of Asimo in action here: http://world.honda.com/Hdtv/Asimo/
From what I can tell Asimo isn’t intended to be a particularly human robot beyond superficial levels. He doesn’t exhibit emotion or learn exterior of his constraints (he can learn areas and navigate them etc. But you couldn’t just sit down and teach him to play the piano without getting in and doing some serious reprogramming). He’s not going to be fooling anything into believing that he’s human any time soon.
The Turing Test is a part of artificial brain that was created by Alan Turing. He stated that the interrogate of whether or not machines could think was too vague, and proposed a test that was more specific. His test, without going into too much detail, complex trying to get a computer to fool population into believing that it was human. The population would type a interrogate into a console and receive a response from the computer on the other side. While there has been much work done on systems trying to pass the Turing test, none of them have succeeded yet. There has also been investigate done into creating machines that can exhibit emotions. However, we’re still a long way off from seeing a motor that can appear to be alive.
The early excitement over Ai led to developers trying to generate a generic reasoning qoute solver that could search through a mass of knowledge that it has acquired and find solutions to any qoute that was thrown at it. Unfortunately this proved almost impossible in practice. Today’s Ai tends to focus on very definite problems and knowledge areas. Devotee Systems are programs that are “Experts” in a definite field and can rejoinder queries linked to only that field. Their applications include curative diagnosis, prestige card application, and other fields where data is to be analyzed.
I haven’t even begun to search for the true extent of Ai in this article, but maybe I’ve piqued your interest. If you want to look into it further, try reading the Wikipedia (free on-line encyclopedia) entry and maybe downloading something like Prolog to have a go and see what real Ai is like. I find it quite keen because it involves a similar mindset to programming as you attempt to break a qoute down adequate for a computer to understand it, but of policy the actual implementation is very different.
Here’s a fun thing to try. Open a copy of Alice (http://www.alicebot.org/), start a conversation with a friend on your messenger program of choice, feed their responses into Alice and send the program’s responses back. See how long it takes before they whether work out what’s happening or get annoyed and block you (which has been the most common follow of my experimentations). Enjoy your exploration of the world of artificial intelligence.
