I’m in progress grokking https://discourse.numenta.org/t/htm-mini-columns-into-hexagonal-grids per Bitking’s pointer, hopefully to update my mind to clear things out.
Am I understanding you correctly that each cortical column contains “an” SDR for “roundness”? While each such SDR is shared by other neurons, they are “local” to its CC as no 2 of them are the “same”?
I’m still skeptic about a feature to have any identity (whether in form of SDR or not) - unlike an object, features are attributive and way too much number of features can come along with an object in reality.
Or features do have SDRs but usually appear as parts of a “union” SDR perceived along with an object? In this case, if a circle and a square (i.e. 2 objects) are perceived by a CC at the same time, how one is not confused that the circle possesses “squareness” and the square possesses “roundness”?
