IBM Unveils Chips That Mimic Human Brain

What:  “IBM has unveiled a new experimental computer chip that it says mimics the human brain in that it perceives, acts and even thinks.”

Why: “The chip, a product of IBM’s three-year-old SyNAPSE project, could become a building block for a new generation of computers designed to emulate the animal brain’s abilities for sensing and cognition–all the while consuming many orders of magnitude less power and space than today’s computers. “We believe we have reproduced the core circuit of the brain in silicon,” says Dharmendra Modha, program lead for IBM Research’s cognitive computing department at the Almaden lab. “All mammal brains are built on the same blueprint. We believe that we have found the core design that encapsulates the key architectural principles of the brain.””

How: “The scientists have built two working prototype designs. Both cores contain 256 neurons, one with 262,144 programmable synapses and the other with 65,536 learning synapses. The team has successfully demonstrated simple applications like navigation, machine vision, pattern recognition, associative memory and classification.”

Watson Slips Up

Unofficial seal of the United States Congress

What: “Some brave — and curious — members of Congress made their way to a Capitol Hill hotel Monday evening to square off against a recent “Jeopardy!” sensation named Watson, the IBM-powered supercomputer that handily defeated the game show’s two most successful contestants in history.”

Why: “Brown [a member of the 25-person team that developed Watson] said his team is close to getting the technology to a point where it is ready for everyday use in the worlds of business and government. But for now, we can continue to enjoy watching Watson show off his formidable trivia skills.”

But: “Holt, a five-time champion on the real “Jeopardy!” show, managed to hold his own against Watson for most of the round…beating Watson by amassing “winnings” of $8,600 to $6,200″
