Artificial intelligence (AI) is the intelligence of machines or software, and is also a branch of computer science that studies and develops intelligent machines and software. Major AI researchers and textbooks define the field as "the study and design of intelligent agents",[1] where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.[2]John McCarthy, who coined the term in 1955,[3] defines it as "the science and engineering of making intelligent machines".[4]
Needless to say, the human brain is the most complex neural structure encountered so far. While a computer can outwork a human in many cognitive tasks, our brain can perform a variety of tasks that no computing machine can even scratch the surface. Just think a bit about imagination – how could a computer ever [...]
As years pass, computers start beating us in more and more fields: math is out of the question, chess, and even jeopardy; but in crossword puzzles, man still beats computer – and easily. In a contest held in New York this weekend, a program designed to work crossword puzzles, came in 141st among 600 human [...]
Researchers from the CalTech University have managed to create the first artificial neural network from DNA, a circuit built out of interactinig molecules that can recall memories based on an incomplete pattern, in pretty much the same way a brain works. “Although brainlike behaviors within artificial biochemical systems have been hypothesized for decades,” says Lulu [...]
The Japanese seem to have not lost one inch of the determination to push science forward after the major earthquake, the tsunamis it generated, and the colateral damage that comes with such a tragic event (power shortages, infrastructure damage, and most of all, radiation danger from nuclear plants). They are now trying to trim the [...]
