Take one neural network that describes what it sees in an image. Provide it with a webcam feed from the MacBook it’s running on. Then, wander around a city and see what happens. Here are the results of exactly that experiment. »
No real faces were used in the making of this face. Instead, it’s what happens when you average out the appearance of a bunch of inanimate objects that people think look like faces. »
Who needs a peep hole when a wifi network will do? Researchers from MIT have developed technology that uses wireless signals to see your silhouette through a wall—and it can even tell you apart from other people, too.
Facial recognition systems use all kinds of clever software to work out who you are and even how you’re feeling. But in this video explainer, Dr Michel Valstar explains how a simple piece on analysis known as a Local Binary Pattern can help detect your expression. »
A team of British researchers have a salacious hypothesis: People like robots more when they exhibit the same sorts of flaws that characterize humans. This makes some sense—after all, the notion of a perfect, all-knowing robot is the stuff of dystopian science fiction. But do you know what’s worse than a perfect,… »
When it comes to image filters, these day’s it often a case of choosing between Instagram’s Hudson or Hefe. But in reality those filters are combination of several, simpler effects — and this video explains how they work. »

We all know that gut-wrenching feeling of reloading a program after a crash, only to learn that hours of precious work have vanished into the ether. But if MIT computer scientists have anything to say about it, a glorious new era of crash-tolerant file systems may soon be upon us. »
Just 45 miles outside New York City in Murray Hill, New Jersey sits Bell Labs: the birth place of lasers, transistors, cellphones and many other modern technologies. In this video, Professor Brian Kernighan remembers what it was like to work there. »
If you use Google’s new Photos app, Microsoft’s Cortana, or Skype’s new translation function, you’re using a form of AI on a daily basis. AI was first dreamed up in the 1950s, but has only recently become a practical reality — all thanks to software systems called neural networks. This is how they work. »
While computers are poor at creativity, they are adept at crunching through vast numbers of solutions to modern problems where there are numerous complex variables at play. Take the question of finding the best delivery plan for a distribution company – where best to begin? How many vehicles? Which stretches of road… »
Data mining, to the uninitiated, sounds like the kind of monotonous computational activity that requires a big computer, a mass of information and little human oversight. But in fact it’s a discipline that blurs the lines between artificial intelligence, machine learning, statistics and other cutting-edge disciplines… »
What is a kilobit equal to? The answer is 1,000 bits, but some people say it should really be 1,024. »
You indirectly use random numbers online every day—to establish secure connections, to encrypt data, perhaps even to satisfy your gambling problem. But their ubiquity belies the fact that they're actually incredibly difficult to find. This is the story of where they come from. »
