IBM pursues computer chips that behave more like brains

Researchers said the new chips have parts that behave like digital 'neurons' and 'synapses.'

In a development with important implications for research and education, IBM Corp. announced Aug. 18 that it has built two prototype computer chips that it says process data more like how humans digest information than the chips that power today’s PCs and supercomputers.

Computers, like humans, can learn. But when Google tries to fill in your search box based only on a few keystrokes, or your iPhone predicts words as you type a text message, it’s only a narrow mimicry of what the human brain is capable.

The challenge in training a computer to behave like a human brain is technological and physiological, testing the limits of computer and brain science. But researchers from IBM say they’ve made a key step toward combining the two worlds.…Read More
