As I continuously learn and use the SP and TM I realized an alternative method to model an SP at least mentally or intuitively. I would like to share a quick overview of this method which is basically using a Deterministic Finite Automaton or DFA to further draw conclusions about an SP’s state. I find this method relatively easy to keep a mental model with and robust as well.
The overview is at https://medium.com/@pepedocs/a-spatial-pooler-model-part-1-26cc96792793
