Facebook wishes to get everyone on the internet, whether that’s by way of typical networks or substantial-flying drones. But to do that, it has to know the place folks basically are. The ideal populace maps available today aren’t precise ample for Facebook’s requirements. So instead of waiting for anyone else to develop a far better map for it, Facebook determined to choose substantial-res satellite photos and use machine understanding to map each residence in these pics.
Facebook’s Jay Parikh, its world-wide head of engineering and infrastructure, and Yael Maguire, the director and head of Facebook’s Connectivity Lab, walked a small group of journalists by way of the rationale and procedure for building these maps.
“Our purpose is to figure out how we can build technologies and comprehending how we can link each particular person on the planet,” Maguire mentioned. At present, the ideal supply of populace knowledge is a map from Columbia College, but it’s not thorough ample due to the fact it only presents a 1km resolution. “If we want to imagine about the ideal technologies to link folks — particularly outside of the metropolitan areas, this is a quite deceptive piece of information.”
About a calendar year in the past, Facebook’s Connectivity Lab teamed up with the company’s AI group and knowledge science workforce.
For this initial operate, Facebook seemed at imagery from 20 nations that handles a overall of 21.six million sq. kilometers. In overall, Facebook’s AI workforce crunched 14.six billion photos. To locate evidence of human settlement in the photos, the workforce employed common machine understanding techniques. It educated the algorithm to figure out which photos incorporate evidence of human settlement by giving it a massive instruction established and then allowing it do its detail, employing a couple thousand equipment in Facebook’s knowledge facilities.
The consequence of this work is the most thorough map of human settlement presently available for these nations.
“This knowledge established is one thing we are quite energized about,” Maguire mentioned. “We are fascinated in finding feedback from the world-wide local community on how it can be employed for connectivity investigation.”
Facebook already partnered with Columbia College to figure out how to make this knowledge available to other people and even even though Facebook is mostly concentrating on connectivity proper now, there are likely a great deal of other use situations for this knowledge, as perfectly.
