Possibly not what you're looking for (certainly not the cheapest option), but we (Lambda School - YC S17) just announced a live, remote class that trains engineers in AI & ML during weekday evenings for six months.
The next one starts in January, and is taught by an MIT grad that taught a similar course at MIT.
