Artifical Intelligence

Artificial intelligence is a highly debatable topic. You either believe that it may be achieved or think it can't, and the middle is a little shady. Artificial Intelligence is the study to create a machine that can act like a human brain, including emotions, and consciousness. This speech will cover the subject of if it can ever be achieved and at what level. This would be a giant technological step. If it is ever achieved, everyday activities such as vacuuming, or laundry, would become automated. The leader in the field of AI is actually not a business, but MIT's Artificial Intelligence Laboratory. It does more ground breaking research in the all fields of AI, including robotics and neural networks, than any other facility in the world. First I will describe the different techniques and fields that fall under AI. The first technique that is used to create intelligent systems is the top-down approach. That is when the computer is given a written set of directions such as "IF that is red, THEN go forward" and it will go from there according to the program. This technique was widely used back in the 1950's when AI was still a mysterious subject, but it has major flaws. To write complex programs that take in

all their surroundings would take hundreds of thousands of lines of code, which no one has the time to write. The newest technique that is being used is bottom-up. That is the arrangement of data into a complex system where all information is connected, like a brain, which is why it is also referred to as a neural network. It is extremely complex and confusing at some points, so I won't describe it here, but you don't need to understand it to answer the question at hand. There are also many different fields of study that fall under AI. The first field that I'll talk about is robotics. This field has been prospering in the '90's. It is not so much the engineering for the robots that is causing the standstill in functionality of these machines, but the computers that control what they do, which is the problem with all forms of AI right now. There is also database processing, which works with the way that a computer sorts and retrieves information. And intelligent software agents that can tell you when to buy and sell stock among many other things. But, what this speech mainly focuses on is the theory behind all this, which has its own field. There are four categories of viewpoints that one may have on this topic. "A. All thinking is computation; in particular, feelings of conscious awareness are evoked merely by the carrying out of appropriate computations. B. Awareness is a feature of the brain's physical action; and whereas any physical action can be simulated computationally, computational simulation cannot by itself evoke awareness. C. Appropriate physical action of the brain evokes awareness, but t
