Facebook Is Using AI To Build The World’s Most Detailed Population Map

Facebook wants to get everybody online, whether that’s by unchanging networks or high-flying drones. But to do that, it has to know where people indeed are. The best race maps accessible now aren’t accurate adequate for Facebook’s needs. So instead of watchful for somebody else to build a improved map for it, Facebook motionless to take high-res satellite images and use appurtenance training to map each residence in these photos.

Facebook’s Jay Parikh, a tellurian conduct of engineering and infrastructure, and Yael Maguire, a executive and conduct of Facebook’s Connectivity Lab, walked a tiny organisation of reporters by a motive and routine for formulating these maps.

Currently, a best source of race information is a map from Columbia University, yet it’s not minute adequate since it usually offers a 1km resolution. “If we wish to consider about a best record to bond people — generally outward of a cities, this is a really dubious block of information.”

About a year ago, Facebook’s Connectivity Lab teamed adult with a company’s AI organisation and information scholarship team.

For this initial run, Facebook looked during imagery from 20 countries that covers a sum of 21.6 million block kilometers. In total, Facebook’s AI group crunched 14.6 billion images. To find justification of tellurian allotment in a images, a group used customary appurtenance training techniques. It lerned a algorithm to figure out that images enclose justification of tellurian allotment by giving it a vast training set and afterwards vouchsafing it do a thing, regulating a few thousand machines in Facebook’s information centers.

The outcome of this work is a many minute map of tellurian allotment now accessible for these countries.

“This information set is something we are really vehement about,” Maguire said. “We are meddlesome in removing feedback from a tellurian village on how it can be used for connectivity analysis.”

Facebook already partnered with Columbia University to figure out how to make this information accessible to others and even yet Facebook is mostly focusing on connectivity right now, there are substantially copiousness of other use cases for this data, as well.
