The Verge: Facebook open-sources algorithms for detecting child exploitation and terrorism imagery. “Facebook will open-source two algorithms it uses to identify child sexual exploitation, terrorist propaganda, and graphic violence, the company said today. PDQ and TMK+PDQF, a pair of technologies that store files as digital hashes and compare them with known examples of harmful content, have been released on Github, Facebook said in a blog post.”
