Light-based neural network could lead to super-fast AI
It's one thing to create computers that behave like brains, but it's something else to make them perform as well as brains. Conventional circuitry can only operate so quickly as part of a neural network, even if it's sometimes much more powerful than standard computers. However, Princeton researchers might have smashed that barrier: they've built what they say is the first photonic neural network. The system mimics the brain with "neurons" that are really light waveguides cut into silicon substrates. As each of those nodes operates in a specific wavelength, you can make calculations by summing up the total power of the light as it's fed into a laser -- and the laser completes the circuit by sending

Google’s DeepMind AI can lip-read TV shows better than a pro
Artificial intelligence is getting its teeth into lip reading. A project by Google’s DeepMind and the University of Oxford applied deep learning to a huge data set of BBC programmes to create a lip-reading system that leaves professionals in the dust. The AI system was trained using some 5000 hours from six different TV programmes, including Newsnight, BBC Breakfast and Question Time. In total, the videos contained 118,000 sentences. First the University of Oxford and DeepMind researchers trained the AI on shows that aired between January 2010 and December 2015. Then they tested its performance on programmes broadcast between March and September 2016. Advertisement By only looking at each speaker’s

Google Is in a Fierce Global Race for Scarce AI Talent
Google is building a new artificial intelligence lab in Montreal dedicated to deep learning, a technology that’s rapidly reinventing not only Google but the rest of the internet’s biggest players. Hugo Larochelle will run the new lab after joining Google from the Twitter, where he was part of the company’s central AI team. It’s a homecoming for Larochelle, who earned a PhD in machine learning from the University of Montreal and remains a professor at the Université de Sherbrooke. Yoshua Bengio, one of the founding fathers of the movement, calls him “one of the rising stars of deep learning.” At the moment, Larochelle is the new lab’s sole hire, but the idea is that he will build a sizable team
