I doubt that it's used in M. "Why not just build M with neural nets from the beginning? Without the right data, neural nets couldn’t provide a service much more powerful than, well, Siri, and Wit.ai’s tech can get things started with relatively little data. “This is a good way to bootstrap. With a few thousand data-points, you can start to build a model,” Lebrun says. “Then, using this model, you get more data, and once you have about a million data points, you go to Yann and get some deep learning.”" [1] [1] http://www.wired.com/2015/08/how-facebook-m-works/ http://www.wired.com/2015/08/how-facebook-m-works/
