Artificial Intelligence

Science fiction has developed the idea of artificial intelligence for a year. Giving machines intelligence often spells the end of mankind as they then rise up against their creators and violently free themselves from oppression. There are lessons like in the movie "Spider-Man 2" in which the robotic arms of Dr. Octavius start controlling his brain, thus forcing actions identified to run it. I've never really an interest in artificial intelligenceuntil recently, when I started studying the basics at the university. The only AI Science Fiction that ever really interested me 'Blade Runner' and his novel "Do Androids Dream of Electric Sheep?" written by Philip K. Dick. The subtext of the story deals with AI becoming self-aware but still unaware of their true nature, a concept that really interested me. Real AI is quite fascinating and very different in many ways than I had expected.

To start with, whatexactly is AI? http://www.dictionary.com defines it as follows:

1. The ability to carry out a computer or other machine for those activities that are normally thought to require intelligence.

2. The branch of computer science concerned with the development of machines with this capability.

If you look at that you may find that the field of AI is actually much farther than many people give it credibility. Even the Google search engine can be said to incorporate someresearch in AI made. The definition of AI, intelligence itself sometimes varies, but it is probably safe to say that a simple statement that if a machine has a certain level of intelligence in some areas it can be called AI.

The AI of the films is usually fully aware of themselves, emotionally, and for all intents and purposes "alive". It's of learning, reasoning able to explain and to deceive. The AI I've experienced (and this is very simple, only scratch the surface of theDepth of studies, AI) is far more specialized, focusing on only one aspect of the problem, which could potentially much greater. There are several areas of research will be conducted in the creation of the humanoid machines of science fiction, but still most are still limited to the realm of fantasy. A very impressive piece of engineering, the Honda ASIMO project. This project has a humanoid robot, created with some remarkable properties. I'm not quite sure whetherit is really a practical use for this (I think they just try to justify their funding with the applications mentioned on the website), but it scores as one of the coolest use 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 is not intended, a particularly human robot via superficial level. He shows no emotion or learn outside its constraints (it can learnAreas and they navigate, etc. But you could not just sit down and teach him the piano without playing it and are) in some serious adjustment. He will not mislead anyone to believe that it is people in the foreseeable future.

The Turing test is a measure of artificial intelligence that was created by Alan Turing. He said that was the question of whether machines could think, too vague, and proposed a test that was more specific. His test without too much detail,involved in trying to use a computer to people in the assumption that it was people get stupid. The people would be a question in a console and receive a response from the computer on the other type. While there was much work to try to systems that do, consist of the Turing test, none of them has yet succeeded. It has also researched in the creation of machines that can show emotions. However, we are still far away from there a machine that can occur live.

EarlyExcitement over AI, the developers try to lead a general ground that the search problem solver with a wealth of knowledge that they acquired and the solutions to every problem that has been thrown at it could create. Unfortunately, proved almost impossible in practice. Today's AI tends to focus on very specific problems and focus of the knowledge areas. Expert systems are programs that the "experts" in a particular area, and answer the questions to only this area. Their applications include medicalDiagnosis, credit card application and other areas in which to analyze data.

I have not even begun to explore the true extent of AI in this article, but maybe I've piqued your interest. If you search further, read the Wikipedia (free online encyclopedia) entry Download and probably have something like a prologue and see what is real, as AI. I find it very interesting because it contains a similar mindset to programming, as you try to break a problem,Down enough for a computer to understand it, but of course the actual implementation varies.

Here is a great thing to try. Open a copy of the ALICE (http://www.alicebot.org/), you start a conversation with a friend on your Messenger program of choice to feed her answers in ALICE and send the program back the answers. See how long it takes before it (either to find out what happened or annoy and block the most common result of my experiments was). Enjoy yourExploring the world of artificial intelligence.
