Technology Review reports that a team of eight artificial-intelligence specialists at Facebook is working on a technique dubbed “deep learning,” which runs on a system of simulated brain cells used to make more precise judgements about a user’s text, photos, and future behavior.

Mike Schroepfer, Facebook’s chief technology officer, says the goal is to cut down the number of posts served by Facebook’s personalized News Feed from 1,500 or so to just 30 to 60 of the most relevant posts. One reason for making the News Feed smarter and more personalized: On mobile devices, which account for more and more of Facebook’s usage, people visit more frequently but more briefly.
