Richard, that sounds interesting. I think it would be possible. We have an intern experimenting with nupic.critic doing something similar. I'm not sure what you mean about getting NuPIC running under Windows, that seems like a completely different problem. Can you explain? --------- Matt Taylor OS Community Flag-Bearer Numenta
