This is not that different from what I called a "NN model" in the memo. > Of course, there are some NN architectures that don't fulfill this > definition, but IMO they are cheating and are just "NN-ish"... > > If an NN architecture like this creates an internal "semantic network" > via self-organization, that's fine. > > Also, if you understood the dynamics of the NN well enough to > explicitly encode knowledge in the NN in a way that worked effectively > within its neuronlike dynamics, that would still be within the NN > paradigm. > > Typical semantic network architectures are not based on closely > neuronlike components, so they don't qualify as NN's in my view.

As I said before, the induction and abduction rule of NARS is not far from Hebbian learning. What I don't like is just the stuff related to vector/matrix calculations, conversion to attractors, and so on.
