So, sorry, but I am looking at the same data, and as far as I am concerned I see almost no evidence that probability theory plays a significant role in cognition at the concept level. What that means, to go back to the original question, is that the possibility I raised is still

[agi] Relevance of Probability

2007-02-04 Thread Richard Loosemore
The only thing that troubles me about this discussion of the relevance of probability theory to AGI is the way it seems to be *partly* founded on an assumption that I, for one, cannot accept. The assumption is that the underlying dynamics of things at the concept level (or logical term

Hi, s. 1) Would anyone currently putting energy into the foundations of probability discussion be willing to say that this hypothetical human mechanism could *still* be meaningfully described in terms of a tractable probabilistic formalism (by, e.g., transforming or approximating

Richard, The assumption is that the underlying dynamics of things at the concept level (or logical term level, if concept is not to your liking) can be meaningfully described by things that look something like probabilities. I never try to accurately duplicate the human mind. Instead, I just

I may have been guilty of writing too compactly again, so here is a quick reply. What I was trying to say was: (1) Suppose the human mind works this way, with the overall intelligence of the system being a (complex) consequence of the interaction of elements whose local structure (the

I would never, ever claim that the human mind doesn't show any regularity in its management of beliefs and concepts. Far from it! It is only the nature of those regularities that are of interest to me. They can be formalizable, or they can be partially complex. Ditto for the idea that I might
