Bldg. 420:040
http://symsys.stanford.edu/
Recent advances in the sciences of the brain have shown us that what
have until recently been nothing more than philosophical conundra are
now poised to become practical engineering challenges. That is,
If you built a robot smart enough to do the dishes, would it
also be smart enough to find them boring?
Come see Judy the Robot and her friend Tom discuss issues like this,
play chess, sing folk songs ("John Henry's Hammer" is Judy's
favorite), argue about which one of them is *really* smart, and
generally carry on, in a show called,
"Judy or What Is It *Like* To Be A Robot?"
Wednesday, October 23 at 4:15 PM in 420-040
Free admission courtesy of the Symbolic Systems Program
"Tom Sgouros's witty play, co-starring the charming robot Judy, is an
imagination-stretcher that delights while it exercises your mind. If
you think you can't imagine a conscious robot, you're wrong--you
can, especially once you've met Judy." -Daniel Dennett, author of
"Consciousness Explained", etc etc
"I laughed a lot, the show is extremely witty... What an amazing
thing!" -Douglas Hofstadter, author of "Godel, Escher, Bach", etc.
"Judy is as much fun as a barrel of wind-up cymbal-monkeys, and lots
more entertaining." -Bill Rodriguez, Providence Phoenix

Vision-Based Hand Gesture Tracking and Recognition
Thomas S. Huang
University of Illinois at Urbana-Champaign
We shall present some results of our research on hand tracking and
gesture recognition in the last 5 years. This research is motivated by
applications in human-computer interaction such as display control in
virtual environments and the manipulation of virtual objects. Although
we have studied both Appearance- Based and 3D Model-Based approaches,
this talk will concentrate on the latter. At any given time instant,
the hand configuration - 6 parameters for the global hand "pose" and
21 finger joint angles (the hand "posture") - is a point the the
27-dimensional configuration space. We track the trajectory of this
point over time using a 3D model-based and analysis-by-synthesis
approach. The challenge is to represent the constraints on hand
posture and finger movement in a compact way and use this
representation to speed up the search in the 21-dimensional space. The
tracking results can then be used to do gesture recognition. Some
preliminary results will be shown on constraint representation and its
use in tracking.
About the speaker: Thomas S. Huang received his B.S. Degree in
Electrical Engineering from National Taiwan University, Taipei,
Taiwan, China; and his M.S. and Sc.D. Degrees in Electrical
Engineering from the Massachusetts Institute of Technology, Cambridge,
Massachusetts. In 1980, he joined the University of Illinois at
Urbana-Champaign, where he is now William L. Everitt Distinguished
Professor of Electrical and Computer Engineering, and Research
Professor at the Coordinated Science Laboratory, and Head of the Image
Formation and Processing Group at the Beckman Institute for Advanced
Science and Technology and Co-Chair of the Institute's major research
theme Human Computer Intelligent Interaction.

Exploiting Document Structure in
Information Extraction and Document
Classification
William W. Cohen
Carnegie-Mellon University
http://www.wcohen.com/
In many tasks involving natural language text, performance can be
improved by using linguistic knowledge---knowledge of the grammatical
structure of the text. However, many documents found on the web are
rich in information while containing little grammatical structure. In
many cases, document structure can provide important clues about the
information contained in a document. I will describe a number of
situations of this sort, focusing on work done by myself and
colleagues. I will outline a number of approaches for representing
document structure, range from shallow "syntactic" views of document
structure to deeper "semantic" views---the distinction here being that
syntactic views of structure are based more directly actual markup
associated with a document, while semantic views are based on the
visual appearance of a rendered document. I will also describe a
number of different and complementary techniques for exploiting
structure in text classification and information extraction tasks
involving structured documents.
About the speaker: William Cohen received his bachelor's degree in
Computer Science from Duke University in 1984, and a PhD in Computer
Science from Rutgers University in 1990. From 1990 to 2000 Dr. Cohen
worked at AT&T Bell Labs and AT&T Labs-Research, and from April 2000
to May 2002 Dr. Cohen worked at Whizbang Labs, a company specializing
in extracting information from the web. Dr. Cohen is currently a
Visiting Associate Professor at CMU's Center for Computational
Learning and Discovery. Dr. Cohen's research interests include
information integration and machine learning, particularly text
categorization and learning from large datasets. He holds five patents
related to learning, discovery, information retrieval, and data
integration, and is the author of more than 60 refereed publications.

Cordura 100
http://cll.stanford.edu/scla.html
Relations between Concept Learning and Attribute Learning
Dorrit Billman
CSLI Computational Learning Laboratory
Visiting Scholar, Psychology, Stanford
How does the structure of attributes influence concept learning and
the structure of concepts influence attribute learning? Much research,
both psychological and computational, has investigated learning new
concepts, while much less has looked at the possibility or nature of
learning new attributes. Representation of instances is typically
assumed to be fixed, and representation of concepts to be built from
this fixed vocabulary. We consider what it would mean to learn a new
attribute, why it might be useful, how to assess whether attribute
learning has taken place, and whether certain types of human concept
learning do indeed produce formation of new attributes.
I will present experiments on the role of 'consistent contrast' in
human concept learning and attribute formation. Consistent Contrast,
is the relation among a set of contrasting concepts when the same
attributes are consistently informative across the contrast set. For
example, animal concepts contrast consistently the extent that people
believe multiple, contrasting types of animals (monkeys, bears,
horses, etc) have informative values on the same attributes (types of
diets, vocalization, etc)-- monkeys eat banana and chatter; bears eat
honey and growl, etc. One set of experiments shows that concepts which
contrast consistently are learned faster and support wider inductions
than alternative concept structures. A second set of experiments
suggests that people form new attributes, by reorganizing features
into alternative values of a new attribute. Our data suggests that
people form new attributes 'in order' to make newly learned concepts
contrast consistently. We compare attribute formation to other types
of representation change discussed in the computational and
psychological literature, and consider why representation change of
several types may be both valuable and difficult.

The Semantic Provinces of 'have'
Tham Shiao Wei
Linguistics Department, Stanford
The forms expressing location and possession are closely linked with
one another, and these in turn bear much structural affinity with the
encoding of existential predication (Bach 1967, Clark 1970, Freeze
1992). The verb HAVE (in languages where it is available) is a point
of convergence in the structural encoding of these three categories of
meaning, able to express possession, location, and existential
predication, depending on the constituents it combines with. This talk
is a foray into the reason for the similarities in the structural
encoding of these meanings, and for their manifestation via HAVE. To
that end, I provide a case study of stative two-place 'have' sentences
in English, exemplified by (1)-(3).[1]
(1) Mowgli has a sister/a crooked nose. (inalienable possession)
(2) Mowgli has a pen. (alienable possession)
(3) The desk has a lamp on it. (location)
Specifically, I argue that, although the case is not immediately
obvious, English `have' is an existential verb that contains an
underspecified relation. In addition, I propose that location and
possession fall within a natural class of relations which I label
"minimal involvement relations" (MIRs). MIRs impose very few, if any,
entailments on their participants -- they are not entailed to be
sentient, agentive, affected, in motion, etc. I suggest that this
characteristic makes MIRs more similar to predicates such as 'have'
than are other classes of predicates such as activity predicates
('hit', 'kick' etc.) or causative predicates ('break', 'kill'). If we
then assume that the range of meanings expressed by a lexical item or
a grammatical construction extends over similar classes of predicates,
we can explain why 'have' expresses location and possession but not
say, 'kick' or 'break'. Time permitting, I will discuss data
pertaining to 'you', the Mandarin HAVE, whose status as an existential
predicate is even more obvious (Huang 1987). Despite clear differences
from English 'have', Mandarin 'you' expresses the same range of
meanings, lending support to the validity of the treatment of English
'have'.
[1] I use uppercase HAVE as a blanket term for the relevant verb
across languages, and reproduce in lowercase the particular verb for a
particular language, e.g. 'have' in English.

Contrast and Conflict in Phonological Representation:
Evidence from Language Change and Neurobiology
Aditi Lahiri
Universitat Konstanz
The research presented here is concerned with the phonological nature
of mental representations of native speakers. Following the FUL-model
(Featurally Underspecified Lexicon, Lahiri & Reetz 2002), we claim
that not all features are present in the mental representation and
that the grammar severely constrains the way in which phonological
contrasts are preserved and utilized in normal language use. Evidence
for the FUL-model comes from language changes which extend and
maintain phonological contrasts. The model is also supported by
results of our MEG and EEG studies which demonstrate different
cortical structures for acoustically equidistant but phonologically
conflicting vowels, and enhanced automatic change detection response
in the brain (mismatch negativity) in instances of feature conflict
(Obleser, Elbert, Lahiri & Eulitz 2001, Eulitz & Lahiri 2002).

Simulating the Evolution of Grammar with Embodied Agents
Luc Steels
Universiteit Brussels and Sony Computer Science Lab, Paris
I will discuss an experimental setup where robots equipped with ways
to perceive and act in the world engage in language games. This setup
is used to examine what kind of cognitive architecture, interaction
patterns, and sensory inputs are needed to evolve natural-language
like communication systems. More concretely, I will focus on the
evolution of a grammar for case, i.e., the expression of event
structure using case markings or similar constructs. The robots
perceive dynamic scenes (such as a hand grasping a ball) and describe
to each other what they see. They start with a purely lexical language
(without any grammar) and then evolve a system of case marking which
is similar to natural languages, in the sense that event structures
are mapped onto semantic roles (agent, patient, etc), semantic roles
to cases (nominative, accusative, etc.), and cases to surface
markings. Semantic roles and cases emerge as part of the grammar
evolution process and are not assumed to be innate.
The basic hypothesis underlying this experiment is that agents try to
optimize their communicative success while minimizing the effort
involved. They do this by adopting specific behaviors, such as always
use the meaning-form relation that had the highest success in the
past, extend meaning-form relations by analogy, overload existing form
with additional meanings, etc. The simulations show that if these
behaviors are adopted, grammar spontaneously emerges and spreads in
the population. Thus semantic roles emerge because the agents re-use,
by analogy, mappings between specific event-object relations and their
markings. By re-use, prototypes for agent, patient, etc., gradually
emerge. (Surface) cases emerge because agents try to pack more
information into the surface form. This requires and additional level
between semantic roles and their marking which again arises gradually.

Hybrid Intelligent Systems for Industrial Data Analysis
Arthur Kordon
Applied Math and Physics Group, Material Science and Information Research
Dept., Dow Chemical Comp.
A novel integrated methodology for industrial data analysis will be
presented and illustrated with various successful applications in The
Dow Chemical Company. The proposed hybrid methodology is based on the
effective synergy among several soft computing approaches (stacked
analytical neural nets, genetic programming, support vector machines,
and particle swarm optimizers). The driving force behind the need for
integration is the requirement of industry for empirical models with
increased robustness and reduced development time. The presentation
will give an overview of the selected approaches and the hybrid
methodology. It will emphasize the implementation issues of
intelligent systems in complex industrial conditions and will give
several examples of successful applications in the area of automating
operating discipline, accelerating fundamental model building,
empirical emulators, and effective design of experiments. The final
part of the presentation will give some feedback of what kind of
unresolved research topics in the area of soft computing are of
interest to industry.
About the speaker: Arthur Kordon is a Research Leader at the Applied
Math and Physics Group within the Material Science and Information
Research Department in The Dow Chemical Company. He is actively
involved in the development and implementation of hybrid intelligent
systems based on neural nets, genetic programming, and rule based
systems. He has more than 40 technical papers in the area of
intelligent systems and adaptive control. His hobby is writing and he
has published two books in his native Bulgarian, the first one,
Markology: The Bulgarian Murphys Laws with two editions in 1991 and
1998, and recently in 2000 he published his second book The Long March
From Communism to Democracy. He was born in Varna, Bulgaria,
graduating from Technical University in Sofia, Bulgaria with a
Ph.D. in Electrical Engineering. He lives in Lake Jackson, TX.

Wireless LAN's in Industrial IT Solutions
Snorre Kjesbu
Technology Program Manager for Wireless Communication, ABB
How has industrial IT changed the automation industry? Is it possible
to convert office automation solutions into industrial IT
solutions. What are the requirements imposed by industry? How are
wireless LANs utilized with such solutions?
The shape of industry is changing from resource-based to
knowledge-based. In such a transition strong focus on Industrial IT
solutions is very important. The presentation will provide an overview
of ABB's philosophy on industrial IT. WLAN is one of the important
technologies that are utilized. A large WLAN pilot installation was
executed at a Gruvon Pulp and Paper Mill in Sweden, resulting in the
ABB pocket portal. The talk will focus on the technical challenges,
trying to outline the basic requirements and how they where solved by
the research scientists at ABB's research laboratories together with
the operators at the paper mill. A previous talk at Stanford in May
introduced the wireless proximity sensor and the Wireless robot
demonstrator at Volvo. The current talk will also provide the newest
update from these pilots.
Snorre Kjesbu is ABBs Technology Program Manager for Wireless
Communication, and currently responsible for all R&D in this area.
