Is there multi-dimensional spatial pooler for NuPIC?

Question

I'm currently working on some image/video recognition systems. I'd like to build it based on NuPIC. But I cannot find a multi-dimensional spatial pooler, which is very important in the vision domain. Should I implement multi-dimensional SP by myself?

Answer 1

With this recent change to the SP, it now supports any number of dimensions. Just set inputDimensions and columnDimensions to any number of dimensions you want (make sure they are the same, though), and the SP will respect the topology of the input and column space.
