Perhaps integration between this site and Metacademy would fit your needs. Metacademy was discussed in a different HN thread[1] recently, and is especially relevant to your query because it seems that the seed topics are machine learning and probabilistic AI.
We'd be totally up for that, Metacademy is fantastic - saw them yesterday too and had fun looking around. They seem to be very focused on Machine Learning at the moment, but could certainly make a great synergy once they've expanded their focus a little.
