Can anyone tell me the details of artificial intelligence (A.I) in computers etc and how its evolved about ?

Question

pls also suggest websites and books where i can learn more on this......have a major project comin up.....

Answer 1

Video of Dave talking to HAL's evil sister: Hallie who has a sweet voice but a bad personality. Dave uses Voice and Speech Recognition software to communicate with Hallie. Dave tries to get Hallie to respond, check emails, and work with Excel. Hallie is always checking with Dave to see if he is OK.

Unfortunately asking for too many details is going to be fruitless. That often gets into proprietary information, and is well guarded.

What I can tell you is that early AI systems basically gathered information which it uses to base its future behaviors. This is the kind of really weak AI that has been in cars for over 20 years.

From what I can tell, this basic beginning led to more complex systems that basically do the same thing, just in more complex ways. This type of system is now in use in a variety of more complex systems, but the main research and development has been in the field of games, which is part of the reason that the details are so protected. (Games are BIG business. The right system means more money.) I have also seen ads for investing firms that supposedly use AI for tracking and picking stocks and other investments. Again, a good reason to protect that type of system.

The problem is that this type of system is only useful in the context that it was created for. That is why it is called Weak AI.

Strong AI, which supposedly has not been implemented yet, is a system that can adapt itself to different contexts. Whether or not this type of system would acheive self awareness or true sentience is a matter of debate. What is true is that a system like that would be much more versitile than one that is limited to a single context. (An example would be a military platform that could function equally well in both recon and attack without having to change software. I think DARPA is working on a such a system.)

Recently progress has been made in the area of creativity. Up until now, "creative thought" by a computer only mimicked the results, not the process. They are only high speed evolutionary processing which relies on random numbers. A theory has been developed recently that would give a computer non-random number based creative thought. But again, the details are proprietary, so they are not available.

there are two main focuses in AI, which presuamable would eventually be merged one day.

first is the engineering of robotics that are able to interact with the enviorment, and perform tasks unaided. this includes the ability to observe and learn from enviorment, but is primarily about setting the basic rules needed to make that work. this is practical research aimed at making the machines of the future. a low level example of this is that vacuum cleaner that cleans the room, using sensors to turn away from walls and stairs.

the second area is more like what we often envision, the thinking machine. this often focuses on language, and basiclay the idea is to have a program that can learn language, and converse with a human, sounding just like a person. programing on this kind of open ended learning is what will likely eventually lead to some kind of computer awareness, while the previous kind would be required to be merged with it, to give it an awareness of it's surroundings.
