This is great news - I was looking at Tensorflow the other day, but on Windows / OSX it doesn't take advantage of my GPUs. For my desktop I was stuck as my new 3440x1440 monitor doesn't, for the time being, work with Xorg's intel driver.

Hopefully this is a viable alternative, I would love to see a online course in machine learning leveraging this. I found http://research.microsoft.com/en-us/um/people/dongyu/CNTK-Tu... on the homepage which looks well put together to start off
