The more time scientists spend designing computers the more they marvel at the human brain. Tasks that baffle (难住) the most advanced supercomputer—recognizing a face, reading a handwritten note—are child’s play for the 3-pound organ. Most important, unlike any conventional computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imitate the brain’s abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an over-grown calculator, it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells, or neurons.
Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform only one task at a time. This approach works best in solving problems that can be broken down into simpler log
A. the conventional computer and the neural computer
