DZ:What does it mean to represent something in the brain "in form of
outlines"?
Again v briefly: when you reach out for something, you follow a line of
action - and have to decide between alternate lines of action. When you move
anywhere in the world, you follow a path, and have to decide between
alternate paths - alternate lines of action. When you look for what caused
something to happen in a physical scene, you follow lines - chains - of
causation. When you perceive a class of object, you perceive it as having
outlines - conforming to stereotypical outlines. When you fit one object
into another - into a box say - you have to observe whether their
lines/outlines will fit together. We even talk of ourselves as "thinking
along such-and-such lines (both specific and general lintes).
We are continually following (and imposing) lines of action and thought.
It's hardly a big stretch to see those lines as represented in the brain -
there to guide the planning of our movements and thoughts. .
Actually, I doubt whether most maths-oriented AI-ers and roboticists would
have much problem with that idea. If you believe that a computer or robot
must be mathematically based, you believe - no? - that it must follow and
must be guided by some kind of lines.
(Diagrammatic lines certainly pervade our entire external culture - they are
there in maths and logic as well as in language and the wider culture)
The main question - no? - is really not whether there are lines but whether
the lines that guide - and must guide - us or any AGI robot through the
world are mathematical or graphic in nature.

Subject: RE: [agi] The many different types of embodiment
Mike,
GO TO THE KITCHEN
is represented in the brain in form of outlines, which then form the
basis for an AGI/robot to pursue a line of action. Study how we
graphically represent these concepts – study pictograms, ideograms and
diagrams – and you get an idea of how the brain must work.
To the extent I understand what you are saying, I don't think I agree with
this at all. We might draw a line to represent GO TO THE KITCHEN because it
is a path through space which is trivially projected onto paper... I don't
see how it implies anything like a line in the brain.
I do get the metaphor "line of action", but don't see any need for such a
strangely literal representational implication. In fact, I don't know what
that would even mean... So I don't "get an idea of how the brain must work"
from your example. This is what I was asking you for -- some coherent
elaboration on what you are talking about in clear language either
describing what the brain does using brain-relevant detail, or what a
computer would do using computer-relevant detail.
What does it mean to represent something in the brain "in form of outlines"?
