Computers programmed with algorithms intended to mimic neural connections &quot;learned&quot; to recognise cats after being shown a sampling of YouTube videos, Google fellow Jeff Dean and visiting faculty Andrew Ng said in a blog post.u00a0 <img alt="" src="/imagedata/2012/jun/Brain_2.jpg" style="width: 347px; height: 346px; " /> &quot;Our hypothesis was that it would learn to recognise common objects in those videos,&quot; the researchers said. &quot;Indeed, to our amusement, one of our artificial neurons learned to respond strongly to pictures of... cats,&quot; they continued. &quot;Remember that this network had never been told what a cat was, nor was it given even a single image labeled as a cat.&quot; The computer, essentially, discovered for itself what a cat looked like, according to Dean and Ng. The computations were spread across an &quot;artificial neural network&quot; of 16,000 processors and a billion connections in Google data centers. The small-scale &quot;newborn brain&quot; was shown YouTube images for a week to see what it would learn. &quot;It &#39;discovered&#39; what a cat looked like by itself from only unlabeled YouTube stills,&quot; the researchers said. &quot;That&#39;s what we mean by self-taught learning.&quot; 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. &quot;Someday this could make the tools you use every day work better, faster, and smarter,&quot; 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 &quot;Terminator&quot; film style glasses that provide Internet information about what is being seen. u00a0
