It sounds like you are asking the community to do your research for you. If you do not have the time to put into learning these concepts, how can you expect other people to have the time to do it for you? We have plenty of resources so you can learn, model, and implement Spatial Pooling. I’m sure you’ve seen the HTM School videos, I’ve recently pointed you to an interactive example, and there is always BAMI, or you can look through the actual SP code in NuPIC, htm.core, Etaler, or HTM.js.
