An organization formed by Jeff Hawkins (inventor of the Palm Pilot)
to study artificial intelligence. Hawkins idea is that lower level
modules in the brain continually try to predict what signals they
will next receive; and it is only when the predictions fail that
signals are passed up to higher (more interconnected) modules, and
it is at the highest level they become conscious thoughts.
I read his book "On Intelligence" a few years ago and recommend it.
It is quite interesting and has some nice ideas on how to implement
an AGI. It conveys a lot of information on neuroscience with a
strong focus on the visual cortex.
He even derives a machine learning model from his ideas, and it
appears to have practical applications:

On the other hand, the excitement appears to have fizzled out after
some initial hype, but maybe I'm just unaware of further progress.
Will look into it.
Pro: I really appreciate his "it's time for computer science to
tackle the brain" attitude, focused on actually building things;
Con: He dismisses the mind-body problem by essentially claiming
that consciousness doesn't even exist. It annoys me, but I can
tolerate it because he delivers interesting ideas and models on the
practical side of things.
Not only I am unable to go to that page, but my browser get really
mad after I tried. Actually, I have lost my connection with the net.
I guess my OS is too old.
Strange, it's a regular wikipedia page. Maybe you can try the mobile
version, which is lighter:
http://en.m.wikipedia.org/wiki/Hierarchical_temporal_memory
May be, tomorrow. Now it works fine. But with mobile version, my non
updated old OS makes weird things.
But from what you say, we might agree on this. That theory is close
to the idea that consciousness is called for when automated part of
the brain don't fit with the situation. We can open everyday our
door without conscious thinking, but if the key appears to not
function well, we get conscious of the situation.
Right, but it is presented simply as a theory of intelligence. One
of the things he mentions in the book, that I really like, is the
possibility that the neocortex uses very long axons that go deep
into the brain and back in a loop as a device to delay signals. The
hypothesis is that it allows the mapping of temporal phenomena into
a simpler atemporal pattern-matching problem.
OK. Nice.
Then, if he claims that consciousness does not exist, well, we have
a problem. Agreed.
Perhaps the problem is not so serious because his theories do not
depend on this assertion. It's more of a side remark, he seems to be
annoyed by the consciousness issue and just avoids it. It's fair
enough, I think.
Oh yes. No problem as long as it does not mock the question publicly,
or eliminate consciousness and person without saying.
I don't have the book with me so I can't check. I will check in the
summer if nobody else comes forward.
OK. I am a bit overwhelmed by the information (like everybody I
guess), so I prioritize with respect of what seems the most
"fun" (divine or cosmic fun perhaps) to me. Nice sum up like this are
useful, thanks.
