It was, as I said, a caricature. However, look, e.g., at the overview graphic of this LIDA paper (page 8) http://bernardbaars.pbwiki.com/f/Baars+&+Franklin+GW-IDA+Summary+in+NeuralNets2007.pdf (the green circle is step 3). > No miracles occur, other > than massively complex spreading activation, implication, and constraint > relaxation, thresholding, attention selection, and focusing, and selection > and context appropriate instantiation of mental and physical behaviors. That "miracle occurs" was not to be interpreted as meaning that the miracle occurred without mechanism but, I hoped, to be recognized as a tongue in cheek way of saying that that this was the point where each system put its (different) "secret sauce". > If you have read my responses in this thread one of their common themes is > how both perception up from lower levels and instantiation of higher levels > concepts and behaviors is context appropriate.

And people have talked about steering of attention, Steve Reed mentioned following moving objects, and so forth. But I haven't seen it given a *primary* place in the architecture -- whenever anybody's architecture gets boiled down to a 20-module overview, it disappears. > So I don't view your alleged missing conceptual piece to be actually missing > from the better AGI thinking.

It gets thrown in piecemeal on an ad hoc basis as a kludge here and there. (and yes, there are lots of specific examples of feedback in many of the architectures, particularly the robotics-derived ones). You see, I happen to think that there *is* a consistent, general, overall theory of the function of feedback throughout the architecture. And I think that once it's understood and widely applied, a lot of the architectures (repeat: a *lot* of the architectures) we have floating around here will suddenly start working a lot better.
