But the fact that X is Y OR X is not Y sure as hell IS A AXIOM, and so is "a
event happens for a reason OR a event does not happen for a reason". And first
you tell me that the above is a tautology that is so obvious that I'm foolish
for repeating it so often, but now you're insisting that it isn't true. So
Chris, who is really confused around here?
X is Y OR X is not Y -- except when that which is being considered exists in a
state of superposition :)
But sure its true in classic logic. And again I raise your bet with a big SO
If X = Y AND Y = Z then X = Z This is also logically true, but also has no
substantial bearing on how the dynamic processes by which the mind arises from
the 86 billion neuron and 100 trillion connection two phase (electro-chemical)
network that comprises our brain

How totally pompous of you. What do you know of my existence, whether it be
drab or dangerously on the edge? You have no knowledge of my existence and for
you to characterize it -- from your position of gross ignorance reveals a
gaping deficiency in your reasoning abilities or else a really bad character
flaw. Could you please refrain from this engaging in these kinds of childish
attributions and characterizations of someone whom you do not know at all but
happen to be arguing with. Since I do not think you are stupid I must conclude
you are pompous, which is not something I would be especially proud of if I

Yes, and that is all the more reason to use reductionism if you want to study
it. If you had to understand everything about it before you could understand
anything about the brain (or anything else for that matter) you would remain in
a constant state of complete ignorance about not just the brain but everything.

AND when did I say random? I deal with randomness -- or more accurately pseudo
randomness and how to account for it and use it -- all the time in my work
life. But I am not referring to random events, I was describing the difficulty
in tracing causality back from an outcome state Y to an originating (within the
frame of reference) state Y. I was making the statement that because of the
chaotic and highly parallelized nature of the brain that very often the attempt
to work back and determine the causes is in practice impossible.
Now hopefully you will finally figure out what I have being trying to
communicate to you and realize that my stating that it is impossible to work
back from result X to initial state Y by trying to rewind events and work back
step by step is not the same thing as saying that the outcome X is the result
of some random process. The brain is not a random state machine, it has a
definite direction of flow and we experience a clear and consistent outcome.
Clearly there is cause and effect -- as well as a fair degree of randomness
that works its way into outcomes along the complex chains of consensus building
neuralcortex algorithms that seem to be operating in us -- and which by the way
DARPA is highly interested in learning more about.

Fractals are amazing and also heavily relied on to generate interesting,
seemingly highly complex and realistic results using rather simple recursively
applied algorithms; that sounds like it must have been a fun project.

Watson was based on self learning algorithms -- if I recall. If I am correct --
and I am pretty sure that the team that developed that software was very much
relying on a self-learning approach and that Watson was hit with probably
hundreds of thousands if not millions of queries in a process of self learning
where the final ready state of the Watson system when it was put up to the
challenge was the outcome of this non-linear approach.
To characterize a self-learning machine that "learned" what associations -- and
what meta-associations as well -- because it is often on the meta information
that algorithms operate -- as an example of determinism is really stretching it.
Watson was so astoundingly successful on Jeopardy precisely - -I would argue --
because it adopted a non-linear and non-directed approach. Programmers did not
provide Watson with the answers, rather over many generations of refinement of
its own pattern recognition algorithms and know association maps -- clearly
under the careful and close direction of the programmers (or is it better to
use the term mentors) -- Watson was able to demonstrate a remarkable ability
to associate a correct answer from a Jeopardy question based on a very rapid
lookups in its vast generalized store of knowledge.
Watson was so successful -- precisely because it did not attempt to impose any
deterministic algorithms, but rather sought to enable a dynamic process of
self-learning after which the system was able to quite successfully discover
pattern matches from often very arcane bits of information.
A very impressive demonstration of how uncannily close to AI a generalized
pattern recognition machine like Watson can be with the state of the art in
self learning systems.
The key term & methodology: is in fact SELF-LEARNING, which by definition is
not pre-determined. The programmers did not encode the answers into Watson;
rather Watson the software system "learned" what pattern recognition approaches
worked and which conversely did not and it "evolved" it algorithms with the
results that were so impressive.

I begin to gather you are the type who will never admit anything. So be it.

I am confused. What do you mean we don't understand what machines are doing?
We do though -- to a large degree and to a fine degree of detail -- understand
how software systems are working -- even in the dynamic dimensions of a given
operational instance. While we may not understand precisely what is happening
or what code will be generated by some code generation process for example
becoming the inputs or model of yet another process; we do have a very good
general idea of how it is all working and how to ensure that the outcomes that
are being generated are of a high fidelity and have predictive value.
Yes some systems have become so deep, vastly extended and multi-nodal in nature
that we probably can no longer really model them completely, but all of the
processes that are at work in these vast distributed systems are well known to
information scientists & engineers. While the detailed knowledge of the inner
workings are beyond our knowledge -- though artifacts of the dynamic process
may exist in logs for example -- they are generally understood in terms of
design patterns etc.
