Where, from all
the recent brain research is the *evidence* that shows brains perform
statistical analysis during pattern recognition? How do you *know* what
the
algorithm is?

We don't know for sure what algorithm the brain actually uses. But,
the best evidence availble strongly suggests very complicated
algorithms and statistical analyses are indeed in play. Learning isn't
just some magical processes. Rather, it seems to be mathemetically and
statistically based.

Sean *what* evidence shows that statistical analysis is performed by a human
brain during pattern recognition? From my reading, the best evidence shows
that it is an *associative memory* process, not statistical analysis.

Machine pattern recognition is also based on associative memory. It
is just that the degree of association requires a great deal of
statistical analysis. Just as machines require this sort of analysis,
it seems quite obvious that the brain's associative memory requires
the same sort of analysis when it comes to useful pattern recognition.

It does?

Perhaps you can provide a reference to any publication dealing with
the way pattern recognition works in humans which concludes that it is
the product of unconscious statistical analysis.

I've already provided several references dealing with the statistics
behind pattern recognition.

They dealt with attempts to use computers to recognise patterns.

The human brain, by all accounts, is a
machine that uses parallel processing of information and data
interpretation.

That doesn't mean that the human brain uses statistical methods for
pattern recognition.

All models based on this concept use statistical
analysis of the data that is processed.

No they don't. Not even all computer techniques rely on statistical
analysis, such as those involving neural nets for example.



If you think otherwise, please do provide your own counter references.

Here's one: http://www.dontveter.com/basisofai/char.html
Here's another: http://foldoc.org/foldoc.cgi?pattern+recognition
And another: http://www-zeus.desy.de/bluebook/ch17/subsubsection2_4_5_5_2.html
Here's the wikipedia entry: http://en.wikipedia.org/wiki/Pattern_recognition
(oh, and before you start misrepresenting what is said here: you *do*,
I hope, understand what the word "or" means, as in the sentence
"Pattern recognition aims to classify data (patterns) based on either
a priori knowledge or on statistical information extracted from the
patterns."

How many do you need before you withdraw your assertion?

Mind you, I'll guess that this is just another of those awkward parts
of the post you'll snip.


Of course, I know that this is one of those awkward questions you
pretend you are answering by posting links to papers which do not
support your assertion, but surely you can't expect *anyone* simply to
take your word for it, given your posting history?

You'd say this regardless of the papers I present or arguments made.

Is that your excuse for not presenting any papers, Sean?
That's pretty lame even by your standards!

It is easy to make this bald assertion.

But Sean, *YOU* are the one making this "bald assertion"!

It is quite another thing to
back yourself up with your own relevant papers suggesting that
learning does not involve any conscious or subconscious statistical
analysis of data.

Sean, it's up to *you* to support your assertion, not anyone else!

That notion is pure nonsense. I mean really, what
is your definition of "statistics"?

The one used by statisticians. You can read the wikipedia article on
it if you want.
