Overview

Artificial intelligence has long been a popular theme of scince fiction movies where a super intelligent computer threatens to take over the world. The reality of AI is very different. Computers can demonstrate varying degrees of artificial intelligence but enough to truly be called intelligent.

 

The first exploration of the concept of AI began with the first computers. Computers were designed to solve problems. If a computer could reason like a human then it would open up immense possibilities.

 

Alan Turing and Colossus

The first computer, built in 1943, was "Colossus" and the team which built it was led by a British scientist, Alan Turing. Alan Turing was the first scientist to actually write a paper on artificial intelligence in 1950. In this paper he proposed a test for AI, which to this date no computer has been able to pass. This test is called The Turing Test.

The First AI

The first use of the term "artificial intelligence" was not until 1956 by an American scientist by the name of John McCarthy who is refered to as the "Father of AI". John Mccarthy also came up with a programming language called LISP which is still used to program computers in AI. LISP allows the computer to learn.

 

Timeline For AI
1943
"Colossus", the first electronic computer was created
1950
The Turing Test was proposed by Alan Turing
1951
Marvin Minksy and Dean Edmonds built first neural network where the computer simulated a rat finding its way through a maze.
1958
John McCarthy and Marvin Minsky founded AI lab at MIT
1958
LISP developed by a team led by John McCarthy. LISP was the first non-procedural programming language which is still used for programming AI
1966
John Weizenbaum wrote a program called "Eliza". The program was like a therapist and asked questions of patients.
1969
Stanford University built a robot called "Shakey" which could recognise shapes and colours and navigate a path through coloured blocks
1970s
The first expert systems appeared
1997
Super computer "Deep Blue" defeated world champion chess player Gary Kasparov
1997
First time AI system controlled a space craft "Deep Space II"
late 1990s
web bots and crawlers developed to give information to search engines for internet
Present
programmers are still trying to develop a computer which can successfully pass The Turing Test

 

The Future of AI

Artificial intelligence is going to play a an increasingly larger part in people's lives as machines incorporating computer chips becomes increasingly more complex and more intelligent. Smart homes, cars that talk, cars that may drive themselves, fridges which automatically order goods over the internet as various items are used are all becoming a part of real life rather than science fiction. Whether it is taking delivery of goods, running a bath, feeding the cat, turning on the washing machine or roasting a chicken: if you are out, the smart house will take care of it. Remote commands such as to water the garden, or feed the family pet for several days, can be sent to most of the computerised appliances via mobile phone. Look at webcast from BBC
