Basically, we seem to have 5 kinds of mechanisms in the knowledge-
That is a useful classification of intelligence-mechanisms, I think.
It is interesting to think that a combination of all of these could
produce something that equates to intelligence.
For example, in chess, the problem of "pattern recognition" (in the
sense that a player recognizes a pattern on the chessboard") would
seem to imply an abstraction, with attendant assertions and implications
based on the classification (aka "definition") that results. Finally,
an executable is needed to do the limited analysis we are capable of.
Of all the aspects, abstractioning is the trickiest. But were such
a module developed, it could be combined with the others to yield
a truly "intelligent" chess playing program that starts, as we all
do, from nowhere.
I suspect that "learning" is really a separate mechanism from
"abstractioning", in that learning is really the adoption of
someone elses abstractions. The "abstractioning" process, in
turn, has 2 forms:
a) The pattern discovery process, where you figure out what
things have in common.
b) The pattern recognition process, where you relate a new
situation to ones that have been previously discovered
The model for intelligence, then, would have a "pattern repository",
which was loaded by a combination of discovery (reasoning) and
learning (adoption of other patterns, which interestingly enough
*also* involves reasoning). Once patterns are stored, they can
be compared to new situations, looking for a fuzzy match.
That process is pretty much what a new chess player goes through,
having no patterns at the outset, followed by some rudimentary
patterns that are seldom of any real help, followed by more and
more patterns that are increasingly more refined.
Machines of that kind would make it possible to objectively rate
one kind of pattern-recognition strategy against another, and
answer questions like, "What is the best way to think about X?",
where X may be the game, or a particular kind of situation.
