The successes and role of alan turing in the field of computer science

I'm not entirely sure how to get started, but the oblique reference to "a now outdated criminal offence" seems unnecessarily vague consider the homosexuality of Alan Turing is commented on in the rest of the article, and considering the phrasing is exactly that in the publicized material linked to. Are you also going to change it when they release Keira Knightley's character poster? She's co-lead in the billing.

Mar 27,  · Although the brain-computer metaphor has served cognitive psychology well, research in cognitive neuroscience has revealed many important differences between brains . Part I of 'Alan Turing, Father of the Modern Computer' provides an overview of Turing's many major contributions to the development of the computer and computing—including his pioneering work in the areas now called Artificial Intelligence and Artificial Life. The Commonwealth Club of California is the nation's oldest and largest public affairs forum. As a non-partisan forum, The Club brings to the public airwaves diverse viewpoints on important topics.

Artificial Intelligence Artificial intelligence AI is the field within computer science that seeks to explain and to emulate, through mechanical or computational processes, some or all aspects of human intelligence. Included among these aspects of intelligence are the ability to interact with the environment through sensory means and the ability to make decisions in unforeseen circumstances without human intervention.

Typical areas of research in AI include game playing, natural language understanding and synthesis, computer vision, problem solving, learning, and robotics. The above is a general description of the field; there is no agreed upon definition of artificial intelligenceprimarily because there is little agreement as to what constitutes intelligence.

Interpretations of what it means to be intelligent vary, yet most can be categorized in one of three ways. Intelligence can be thought of as a quality, an individually held property that is separable from all other properties of the human person. Intelligence is also seen in the functions one performs, in actions or the ability to carry out certain tasks.

Finally, some researchers see intelligence as a quality that can only be acquired and demonstrated through relationship with other intelligent beings.

Each of these understandings of intelligence has been used as the basis of an approach to developing computer programs with intelligent characteristics. The term itself was coined six years later by mathematician and computer scientist John McCarthy b. The earliest approach to AI is called symbolic or classical AI and is predicated on the hypothesis that every process in which either a human being or a machine engages can be expressed by a string of symbols that is modifiable according to a limited set of rules that can be logically defined.

Early life and career

Just as geometry can be built from a finite set of axioms and primitive objects such as points and lines, so symbolicists, following rationalist philosophers such as Ludwig Wittgenstein — and Alfred North Whitehead —predicated that human thought is represented in the mind by concepts that can be broken down into basic rules and primitive objects.

Simple concepts or objects are directly expressed by a single symbol while more complex ideas are the product of many symbols, combined by certain rules. For a symbolicist, any patternable kind of matter can thus represent intelligent thought.

Symbolic AI met with immediate success in areas in which problems could be easily described using a limited domain of objects that operate in a highly rule-based manner, such as games.

The game of chess takes place in a world where the only objects are thirty-two pieces moving on a sixty-four square board according to a limited number of rules. The limited options this world provides give the computer the potential to look far ahead, examining all possible moves and countermoves, looking for a sequence that will leave its pieces in the most advantageous position.

Other successes for symbolic AI occurred rapidly in similarly restricted domains such as medical diagnosis, mineral prospecting, chemical analysis, and mathematical theorem proving. Symbolic AI faltered, however, not on difficult problems like passing a calculus exam, but on the easy things a two year old child can do, such as recognizing a face in various settings or understanding a simple story.

McCarthy labels symbolic programs as brittle because they crack or break down at the edges; they cannot function outside or near the edges of their domain of expertise since they lack knowledge outside of that domain, knowledge that most human "experts" possess in the form of what is known as common sense.

Humans make use of general knowledge—the millions of things that are known and applied to a situation—both consciously and subconsciously. Should it exist, it is now clear to AI researchers that the set of primitive facts necessary for representing human knowledge is exceedingly large.

Another critique of symbolic AI, advanced by Terry Winograd and Fernando Flores in their book Understanding Computers and Cognition is that human intelligence may not be a process of symbol manipulation; humans do not carry mental models around in their heads. Hubert Dreyfus makes a similar argument in Mind over Machine ; he suggests that human experts do not arrive at their solutions to problems through the application of rules or the manipulation of symbols, but rather use intuition, acquired through multiple experiences in the real world.

He describes symbolic AI as a "degenerating research project," by which he means that, while promising at first, it has produced fewer results as time has progressed and is likely to be abandoned should other alternatives become available.The Tunny machine encrypted each letter of the message by adding another letter to it.

(The process of adding letters together is explained in the next paragraph.) The internal mechanism of the Tunny machine produced its own stream of letters, known at B.P.
