You may want to look through this thread and see if it helps with understanding the SP operation.

What does "the receptive field center" mean in SP?

[QQ%E6%88%AA%E5%9B%BE20181102152138] Sorry for disturbing. I’m reading the paper The HTM Spatial Pooler—A Neocortical Algorithm for Online Sparse Distributed Coding by Cui. While confused that in the part of fault Tolerance, it discuss the “receptive field center” with respectively showing the picture above. What does the “receptive field center” mean?
