John Langford and Yann LeCun are teaching a large scale machine learning class at NYU that was announced to not be a MOOC. See: NYU Large Scale Machine Learning Class [Not a MOOC]
However, see: Remote large scale learning class participation.
John and Yann have arranged for lectures to be posted with slides with one day delay and have a discussion forum if you are interested.
Still not a MOOC, but a wonderful opportunity for those of us who cannot attend in person.
