I would greatly appreciate if someone could help me find a Datalog
language (deductive databases) I could download and use. A 1-month
evaluation version would be just fine.

I did try http://www.dbai.tuwien.ac.at/proj/dlv but it didn't run on
Windows XP nor on Windows 2000.

Thank you

I'd be interested in an extension to csp Module (csp.py) which would
hand dle Higher-order Constraints as suggested on page 140, or
equivalently discussion of exercise 5.11.

I'd be glad to try to implement such a beast.  I think the method
would be to define 'neighbors' groups for example neigbors = [[O R
X1],[X1 W  U X2],[X2 T O X3],[X3 F]]
A parse neighbors would split these into dictionary elements O:[O R X1]
R:[O R X1] X1:[O R X1] etc.

Then each reference to elements of neighbors list must be examined and
in most cases modified to properly handle lists of variables

The definition of the constraints function needs to be modified
it could be constraints(A,a,B,b...) with alternating vars and values
or constrains(Varlist,Vallist) with lists of variables and values.

Does this seem like a good way to go, or is it heading up or down a
blind alley?

A significant revision to my earler thoughts on this issue:

After rereading problem 5.11 the tuple '[X Y Z]' should parse to
{'X':['Y','Z'],'Y':['X','Z'],'Z'['X','Y']}

Since this file has been mentioned recently, I'd like to ask how
finished it is. I tried running solve_zebra, and it bombs out with an
error. Also, it doesn't look like some of the other problems (like
N-Queens) have a direct way to execute.

The zebra problem is difficult; you may have run out of memory.  What
error msg did you get?  You should get an answer eventually, but it
should take several minutes.

I added some example calls for N-Queens and the map problems.

I also moved the code to http://aima.cs.berkeley.edu/python

It all depends on what you mean by "feelings".

If you extend the question somewhat to "Can purely algorithmic processes
in a system result in the system having feelings", then you get one of
the hot topics of recent philosophy of mind. Important players are Ned
Block, David Chalmers, Thomas Nagel, John Searle, Sidney Shoemaker and,
of course, Daniel Dennett.

Basically, the debate boils down to an unmitigated opposition between
those who believe in (philosophical) Zombies and those who don't.
Zombies in this sense are creatures who behave absolutely
indistinguishable from ordinary people -- but who don't feel anything,
they don't have "qualia" (philo jargon for raw feelings).

So, if you would insist that feelings are something above and beyond
behavior, utterances, predispositions -- that is, things that can be
discernd from a scientific, third-person perspective. And if you
instead claimed that you have privileged, exclusive, first-person
access to "what it's like". Well, then there's no way from algorithmic
process to feelings.

People who favor this big-R Realist view of qualia conceive of the
feelings themselves as something in need of explanation. In my opinion,
this is a futile endeavor. Instead, I side with those (Dennett), who
more or less see our *verbal reports of feelings* as the thing to
explain. Feelings in this sense are (small-r) real, too, as they
obviously have an explanatory role in our mental economy.

HTH,
Michael

Subject: CSP chapter

bcorfman

I finished reading the CSP chapter (the PDF file posted on the web
site)  over the weekend. I have a comment about one of the sentences
in section 5.2 talking about arc consistency.

On p. 146, it says that "although this [arc consistency] is
substantially more expensive than forward checking, the extra cost is
usually worthwhile." This doesn't seem to agree with the CSP survey
paper by Kumar (1992), which mentions that for loosely constrained
problems like N-queens that arc consistency is too expensive. (This is
also borne out by my own experience writing loosely-constrained CSPs
that have used AC-3.)

In this regard, I think that it would be good for section 5.2 to
actually have a brief mention of tightly constrained problems vs.
loosely constrained problems that would lead into a discussion of why
you would only apply FC vs. MAC/AC-3.

My 2 cents.

Best regards,
Brandon

These are /research/ questions. For c) minimum you have to have two, input
and output layers. a) and c) and number of links (it may not necessarily
be a fully-connected network) are a research component. Try :) To be
computationally-feasible on a "commodity" class machines don't try too
many hidden layers with many neurons in a fully-connected network.

To give a few numbers: in one of our projects a net of 512 input neurons,
32 output neurons, a hidden layer of 1024, then 512, then 256 (a total of
5 layers) on my PIII, 550Mhz, 512Mb of RAM has never completed because it
ran out of memory.

You will find many rules of thumb to say exactly how many layers or
