Checking in on this thread. I want to make sure you are aware of the Cerebro2 project: https://github.com/chetan51/nupic.cerebro2
This is a visualization tool for NuPIC that Chetan Surpur built. Here is a screenshot from the 3D view: https://plus.google.com/103149935262887649090/posts/6St7gZFFapn It looks a bit different since this screenshot was taken. There is also a 2D viewer in the current version. - Jeff On Wed, Jun 18, 2014 at 1:03 AM, Ruaridh O'Donnell < [email protected]> wrote: > Hello Yuwei, > > Thanks for the input. > > I agree that visualising 2D sdrs is hard.
