I’ve just updated the post above to improve the organization of the sections and the definitions. I also removed unfilled and relatively unimportant definitions (with respect to the HTM theory and NuPIC). There are still some definitions which, IMHO, do not seem to me to be very consistent, reliable and clear.
@rhyolight Couldn’t this wiki be merged with HTM Cheat Sheet? Or, alternatively, we could just have this glossary specific for NuPIC (and, in general, implementation-related) terms, but the documentation, IMHO, should be enough for this purpose.
