Twitter Makes Recommendation Algorithm Open Source, Reveals Source Code.

Twitter has released a portion of its source code to the public, including the algorithm it uses to recommend tweets in users' timelines. The move is part of Twitter's efforts to be more transparent, but the company has excluded any code that would compromise user safety and privacy or the ability to protect its platform from bad actors. The algorithm is made up of multiple models, including a model for detecting abusive content, determining the likelihood of a Twitter user interacting with another user, and calculating a Twitter user's "reputation." The release of the source code comes after several controversies involving tweaks to Twitter's recommendation algorithm in recent months.
