I don't think the HTM can be described as discreet-based-AGI. However, discrete network models can take on so many properties of the network models that some of the distinctions may be more theoretical or based on some appreciation of model confluences.
I think that discrete-based AI is a stronger base to work on just because concepts can be described so concisely and relative properties (like the abstraction of varieties of relations that may have an implicit or correlated impact on some concept) can be described soundly. The problem is complexity and what I am suggesting in this thread is that perhaps the combinatorics of discrete systems should be considered fundamental to systems that have a strong logic-like basis instead of being seen as an auxiliary that is used in analysis or specialization of these systems. However, I am very interested in the SDR paper and I will read it carefully. Jim Bromer On Mon, Jun 8, 2015 at 9:35 PM, Matt Lind <[email protected]> wrote: > Jim: > > Agree.
