Contact information you’ve never given the network gets associated with your account, making it easier for Facebook to more completely map your social connections. (via Slashdot)
Feature Visualization (Distill) — How neural networks build up their understanding of images. Wonderfully visual.
Mapping’s Intelligent Agents — Industry players are developing dynamic HD maps, accurate within inches, that would afford the car’s sensors some geographic foresight, allowing it to calculate its precise position relative to fixed landmarks. […] Yet, achieving real-time “truth” throughout the network requires overcoming limitations in data infrastructure. The rate of data collection, processing, transmission, and actuation is limited by cellular bandwidth as well as on-board computing power. Mobileye is attempting to speed things up by compressing new map information into a “Road Segment Data” capsule that can be pushed between the master map in the Cloud and cars in the field. If nothing else, the system has given us a memorable new term, “Time to Reflect Reality,” which is the metric of lag time between the world as it is and the world as it is known to machines.
