what's next -- soul for computers?

This is your last chance. After this, there is no turning back. You take the blue pill – the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill – you stay in Wonderland and I show you how deep the rabbit-hole goes.
Google teaching computers to mimic human brain

SAN FRANCISCO—Google on Tuesday said it was dabbling with getting  computers to simulate the learning process of the human brain as one of the unusual projects for researchers in its X Lab.

Computers programmed with algorithms intended to mimic neural  connections “learned” to recognize cats after being shown a sampling of  YouTube videos, Google fellow Jeff Dean and visiting faculty Andrew Ng  said in a blog post.

“Our hypothesis was that it would learn to recognize common objects in those videos,” the researchers said.

“Indeed, to our amusement, one of our artificial neurons learned to respond strongly to pictures of… cats,” they continued.

“Remember that this network had never been told what a cat was, nor was it given even a single image labeled as a cat.”

The computer, essentially, discovered for itself what a cat looked like, according to Dean and Ng.

The computations were spread across an “artificial neural network” of 16,000 processors and a billion connections in Google data centers.

The small-scale “newborn brain” was shown YouTube images for a week to see what it would learn.

“It ‘discovered’ what a cat looked like by itself from only unlabeled YouTube stills,” the researchers said.

“That’s what we mean by self-taught learning.”

Google researchers are building a larger model and are working on ways to apply the artificial neural network approach to improve technology for speech recognition and natural language modeling,
according to Dean and Ng.

“Someday this could make the tools you use every day work better, faster, and smarter,” they said.

Dean and Ng conceded that there is a long road ahead, since an adult human brain has around 100 trillion connections.

Google X Lab headed by company co-founder Sergey Brin is known for  its work on innovations such as a self-driving car and “Terminator” film  style glasses that provide Internet information about what is being  seen.

Google made it big once again! This invention is not as if it's just another Manitowoc ice maker of sorts -- this is a thinking software. Have you decided which pill to take when the time comes? Hehehe.
