Hi Morre,
Attached is a link to an AI / Neural network for dealing with the spam problem. It has some
nice ideas.

Hi Morre,
This is the article I would like to present in the next AI class.
Thanks,
Liran.
Within three to five years, we could see a search engine that could extract specific
facts, draw inferences and organize those facts based on a few key words

Hi Morre,
This is a link that describes a baby bot / AI upbrought in MIT. I made a Tamzit of the page:
"working from the bottom up and organizing itself, like life does, into greater and greater
complexity."
They plan before long to give Ripley a verbal-comprehension test
administered to children. They expect that, as he is taught increasingly
abstract words, he will increasingly develop the capacity for abstract
reasoning.
"Ripley, how heavy is this?"
"How heavy is what?"
A metal block is placed in Ripley's mouth. He flexes his neck up and down,
hefting the block, as a human would flex his arm to test the weight of an
object.
"It is very heavy."
"It's perfectly aware and capable of knowing how heavy things are," says Kaiyuh Hsiao, 25. "I simply haven't programmed it to feel pain [when it lifts
something too heavy]. The same way as a human, its motors heat -- its
muscles get sore -- and I think there's a very great analogue there, but we
haven't chosen to make use of it yet."
Ripley learns language by looking at an object, touching it and hearing the word for it. In the
media lab it is called "grounding." The sight and touch of an object is linked -- grounded -- to
the sound of thespoken word. It is exactly how a human infant learns her first words.
Ripley is about to have his few fragments of canned, programmed speech deleted -- the
equivalent of George W. Bush losing his Teleprompter. Thereafter, Ripley will speak to
humans only with the language he has learned from his environment. If it isn't out there for
Ripley to experience somehow, he won't have a word for it.
Even the grammar of language helps. "By virtue of Ripley's perceptual system," Dr. Roy says,
"the world is parsed into objects -- bean bags, balls, etc. -- that have properties: Blue. Large.
Heavy. This representation of the world as objects with properties forms the basis for nouns
and adjectives.
"This is an important point -- that the perceptual system provides a starting point for the
language system to create parts of speech, which in turn is the basis for learning syntax. Over
time, the learner can use this starting point . . . [to] understand that nouns reach beyond
objects. Think of 'the heat,' 'the flight.' "
"By the time you have traced all connections from language to non-linguistic aspects of the
human -- perception, motor control, planning, visual imagery, and so on -- there will be no
aspect of a human left disconnected from language," says Dr. Roy. "The human genome is
the language genome."
The virtual simulator with which Ripley is now being equipped, says graduate student Nick
Mavridis, 29, from Greece, will enable the robot to see himself bend down to muzzle a
beanbag, giving him an experience of his body. The simulator also will allow Ripley to retain
an image of objects he saw a moment ago but which are now, for example, behind him.
If he is told to find a green beanbag that is behind him, he will know where to locate it by
"looking" into his simulator. In linguistics terms, it is the third side of what is known as the
semiotic triangle: There's the real object (the green beanbag), the label (the name of the
beanbag) and the thought (the image of the beanbag the simulator provides).
Likewise, if a ball rolls past him, the simulator will enable Ripley to predict where it is rolling to.
Which means Ripley will have to understand the laws of physics. Eventually, he will
distinguish between animate and inanimate objects -- a distinction, Mr. Mavridis notes, that
language doesn't always make. "We say, 'The car is coming,' when it is the driver of the car
making it come."

MORRE:
THIS IS AN EMAIL I RECEIVED RECENTLY CONTAINING A PROPOSAL
FOR A SYMPOSIUM ON METACOGNITION IN COMPUTATION
(AAAI – American Association for Artificial Intelligence).
Dear friends and colleagues,
We intend to propose a AAAI Symposium on Metacognition in Computation.
As part of the proposal process, AAAI asks that we submit the names of
individuals interested in the topic; you have been identified as
someone likely to be in this category. If you would indeed be interested in
seeing a symposium on the topic of Metacognition in Computation, please
reply to this mail, and we will put your name on the list.
Expressions of interest do not commit one to actually participating in the symposium.
A draft of the symposium description is pasted below. Suggestions for
improving the description, or for specific topics which you think
should be included, are most welcome.
Sincerely yours,
Mike Anderson, University of Maryland, College Park
Mike Cox, Wright State University
Tim Oates, University of Maryland, Baltimore County

Proposal for Symposium on Metacognition in Computation
The importance of metacognition in human thinking, learning, and problem solving is
well established. Humans use metacognitive monitoring and control to choose goals,
assess their own progress, and, if necessary, adopt new strategies for achieving those
goals, or even abandon a goal entirely. Absent-minded Professor Doe, for instance,
almost always forgets his lunch. He has an adequate recovery plan for this: he simply
goes to the school cafeteria. However, as the school cafeteria is expensive,
this strategy is wasteful. Thus, Professor Doe employs metacognitive reflection,
realizes the frequency with which he forgets his lunch, and adopts a special strategy to
help him remember: he sticks a note on his mirror. In a similar vein, students
preparing for--or taking--an exam will make judgements about the relative difficulty
of the material to be covered, and use this to choose study strategies, or which
questions to answer first. Not surprisingly, in these cases, accuracy of metacognitive
judgements correlates with academic performance. Thus, understanding human
metacognition has been an important part of work on automated tutoring systems, and
has led to the design of methods for using computer assistants to help improve human
metacognition.
Recently, however, there has been growing interest in trying to create, and investigate
the potential benefits of, intelligent systems which are *themselves* metacognitive. It
is thought that systems that monitor themselves, and proactively respond to problems,
can perform better, for longer, with less need for (expensive) human intervention.
Thus has IBM widely publicized their "autonomic computing" initiative, aimed at
developing computers which are (in their words) self-aware, self-configuring, selfoptimizing, self-healing, self-protecting, and self-adapting. More ambitiously, it is
hypothesized that metacognitive awareness may be one of the keys to developing
truly intelligent artificial systems. DARPA's recent Cognitive Information Processing
Technology initiative, for instance, foregrounds reflection (along with reaction and
deliberation) as one of the three pillars required for flexible, robust AI systems.
On the other side of the coin, it has also been established that metacognition can
actually interfere with performance. That is, metacognition is no panacea, and
therefore one of the issues which requires further inquiry is the scope and limits of its
usefulness. Furthermore many researchers still argue over the most useful definition
of metacognition. Is it just cognition about cognition, or is it more useful to include
such things as monitoring the outcomes of one's own actions in the world?
The proposed workshop is intended to bring together researchers from computer
science, cognitive science, linguistics, psychology, philosophy, etc., interested in
exploring, reporting on methods for, and evaluating the worth of, implementing
metacognition in AI systems. Possible topics include:
-Reports on implemented metacognitive systems
-Computationally tractable models of human metacognition
-Methods for evaluating metacognitive systems
-Methods for implementing metacognition in heterogeneous systems
-Evaluation of different architectures for implementing metacognition
-Domains and/or problems for which metacognition is useful/essential
-Formal and/or knowledge-representation issues in metacognition
-The limits of metacognition (including cost/benefit analyses)

Hi Morre,
here's a nice game I found online..
http://q.20q.net/q.cgi
20Q.net is an experiment in artificial intelligence. The program is very
simple but its behavior is complex. Everything that it knows and all
questions that it asks were entered by people playing this game. 20Q.net is a
learning system; the more it is played, the smarter it gets.
I played with it and it guessed right what I thought of after 30 questions.
after revealing the answer it writes a summary where it written what
questions I answered 'wrongly' according to its knowledge and what it
doesn't know yet about the object.
See you Tuesday,
Merrav.
