Hello,
It i strue that no solid proof have been established that humans think
fuzzy, but it is a fact that human brain learns most of the things in a
trial-and-error scheme. Artificial neurons (software) can simulate in much
detail the basic function of biological neurons and so far we know that the
brain has no binary "static" logic as computers do. A neuron output
fluctuates between two boundary values (say, "0" and "1") but all the values
in between are used to characterize an unknown or ambiguous input, something
that works much like a fuzzy fuction, not binary for sure. Dr. R.Penrose has
some interesting ideas how real human neurons work in a much more
complicated way, using quantum physics properties in signal propagation, but
the fact is that all reasoning and logical associations we normally may be
traced down to simple fuzzy mappings.
My point is, the question is not whether fuzziness is a real human brain
proparty, but rather how realistic are the current fuzzy (or ANN) models -
usually the goal is to approximate human's optimum for a specific function,
not the real human brain itself (something that is far beyond our current
and near future technological abilities).
