Teamwork: Practice and New Theory
Milind Tambe
University of Southern California
For the past several years, we have been conducting research in
teamwork, a critical capability in a range of multiagent domains. I
will present results from two key aspects of this research. First,
inspired by the need for team-coordination flexibility and
reusability, we have been developing STEAM/TEAMCORE, a general
teamwork model (team coordination algorithm). I will discuss the
STEAM/TEAMCORE algorithm, the associated software infrastructure, and
present results from its reuse across several different domains, e.g.,
synthetic helicopter pilot teams, RoboCup soccer teams, "Electric
Elves" personal assistant teams, recent work on human-robot teams etc.
Second, as we develop general team-coordination specifications and
algorithms, there is now a critical need for a new theoretical
framework to analyze complexity-optimality tradeoffs in competing
algorithms. To this end, I will present Communicating Markov Team
Decision Problems (COM-MTDPs), that are based on decentralized,
communicating POMDPs. COM-MTDPs provide us complexity results for key
types of teamwork domains, and allow us to compare complexity and
optimality of different coordination algorithms.
* Portions of this research have been conducted in collaboration with
members of the TEAMCORE research group ( http://www.isi.edu/teamcore ).
About the speaker: Milind Tambe is an Associate Professor of Computer
Science at University of Southern California(USC), and a project
leader at USC's Information Sciences Institute. He received his
Ph.D. from the School of Computer Science at Carnegie Mellon
University. His interests are in the areas of multi-agent systems,
specifically multi-agent teamwork, adjustable autonomy, and
distributed negotiations and he has published extensively in these
areas. A current member of the board of directors of the International
foundation for multiagent systems, he has also served on the board of
trustees of RoboCup, the Robot World Cup Federation. He is currently
on the editorial board of the Journal of Artificial Intelligence
Research (JAIR), Journal of Autonomous Agents and Multi-agent Systems
(AAMAS) and IEEE Intelligent Systems. He was also the chair of the
organizing committee for the first Americas Agents School and program
co-chair of the International conf on multi-agent systems (ICMAS)
2000.

Technology in Golf Equipment Design and Development
Steve Ehlers
Callaway Golf
Golf is a game with a long history and, as a result, it is rich in
tradition. Yet, it has seen many changes and technology has often
played a significant role in these changes. For most of the game's
history technological changes were brought about by the appearance of
new materials and fabrication methods. In the modern era of golf
equipment, which began in the mid 1960's, progress has been driven not
only by advances in materials and processes, but also by advances in
such areas as computational power, information technology, software,
biomechanics and measurement devices.
In this presentation key technologies and their contribution to
improvements in golf equipment will be addressed. Emphasis will be
placed on modern developments with some historical background. An
overview of the golf equipment research and development process will
be presented. Examples of technology applications will include new
materials and processes, modeling and simulation, analysis and
measurement of impact, shaft design, swing measurement and analysis,
acoustics and golf ball design.
About the Speaker: Dr. Steven M. Ehlers is Senior Director of Research
and Testing in the Research and Development Group of Callaway Golf
Company in Carlsbad, California. He is responsible for a group of
about 80 people tasked with identifying and pursuing advanced
technologies, developing new measurement systems, analyzing test data,
creating custom design/analysis software and conducting product
testing.
Prior to joining Callaway Golf in 1997 Dr. Ehlers spent almost 20
years in aerospace research and development in the areas of advanced
materials, structures and structural dynamics with applications to
aircraft, spacecraft and missiles. His primary areas of interest
include advanced composite materials, adaptive structures,
dimensionally stable structures, low observables technology and the
management of R&D. Dr. Ehlers received his BS, MS and PhD in
Aeronautical Engineering from Purdue University.

UC BERKELEY CIS SEMINAR

Signal analysis and geometry of immersive sensing
Kostas Daniilidis
University of Pennsylvania
http://www.cis.upenn.edu/~kostas/
Immersive visualization is rapidly becoming very popular with the
dissemination of platforms enabling switching among viewpoints and
directions. While it might look as a pure graphics problem if the
content is virtual, it is a problem of immersive visual sensing if we
visualize a real world and in real time.
Immersive sensing is best described by the notion of the plenoptic
function. In this talk I will start with describing tele-immersion, a
system that amplifies the sense of co-presence in the Internet. Then,
I will provide ways to analyze samplings of the plenoptic function
beyond the traditional perspective plane starting from omnidirectional
systems with a single viewpoint.
I will present a new unifying theory of panoramic image formation
covering all central omnidirectional sensors as well as any
conventional pinhole camera. The model is based on a spherical
projection followed by a projection from the sphere to the
omnidirectional plane. The natural domain to process an
omnidirectional signal is the sphere considered as a homogeneous space
with the group action of rotation. By applying a Fourier transform on
rotations we are able to obtain direct attitude information without
point or line correspondences.
To describe more general mappings of omnidirectional planes we
consider a new representation where the omnidirectional plane is
lifted to a 3D circle space where transformations preserving points
can be modeled as elements of the Lorentz group SO(3,1). Such a
mapping models also the intrinsic geometry of an omnidirectional
camera and it turns out that it drastically simplifies the problem of
3D-motion estimation. The additional robustness of of a huge field of
view make such sensors irreplaceable in navigational tasks.

Lessons for the Computational Discovery of Scientific Knowledge
Pat Langley
Computational Learning Laboratory, CSLI
mailto:langley@csli.stanford.edu
In this talk, I review early analyses of machine learning
applications, along with more recent treatments of successful
discoveries of scientific knowledge. Although the two problem areas
have much in common, I use recent work on computational discovery in
Earth science and microbiology to illustrate some important
differences. The lessons that emerge from these efforts run counter to
some rhetorical claims and assumptions that are widespread in the
machine learning and data mining communities. For example, for many
scientific problems, it is more desirable to revise models than to
construct them from scratch, as emphasized by most data mining
researchers. Another difference is that scientific data are often rare
rather than plentiful, despite traditional claims by the data mining
community about the abundance of data. These observations and others
suggest the need to explore research paths which are quite distinct
from those that currently dominate the field.
This talk repeats material from a presentation at the ICML-2002
Workshop on Data Mining Lessons Learned. The associated paper is
available at http://www.isle.org/~langley/papers/discovery.dmll02.ps .

Video Interfaces for Entertainment
Richard Marks
Manager R&D Special Projects, Sony
Natural, versatile man-machine interfaces can be created by processing
live video input from a digital camera. Movements of either the user
or simple hand-held props drive an engaging entertainment
experience. The greatest level of interactivity can be produced by
mixing live video of the user with computer-generated graphics. The
low cost of digital cameras and processors has recently made such
computer vision interfaces viable, even for a cost-sensitive market
such as console gaming.
About the speaker: Richard Marks was an Avionics major at MIT before
getting his PhD at Stanford in the area of visual sensing for
underwater robotics. He then joined Teleos Research, a computer
vision start-up that was later acquired by Autodesk. He departed and
consulted for a year, before the unveiling of the PlayStation2
hardware inspired him to join PlayStation R&D. His research focus has
been studying real-time video input to the PS2, and he now manages R&D
Special Projects, which includes Man-Machine Interfaces and Physical
Simulation.

NLP READING GROUP
on Friday, 27 September 2002, 2:15pm
Margaret Jacks Hall, Room 460:301
http://www-nlp.stanford.edu/nlp/nlpgroup.html
Allow me to draw the attention of Stanford newcomers to the Natural
Language Processing (NLP) reading group, an informal weekly forum for
those interested in NLP to share research results or draw attention to
works which are felt to be of general interest to the local NLP
community. The NLP reading group is to be held this year on Fridays
from 2:15 to 3:30 in Margaret Jacks Hall (the Linguistics building),
room no. 301. Note the change of time (slight) and location (great)
over last year.
The first meeting for the quarter is to be held this Friday (Sep 27),
with Dan Flickinger (CSLI) to present as follows:
The LinGO Redwoods Treebank ---
Motivation and Preliminary Applications
The LinGO Redwoods initiative is a seed activity in the design and
development of a new type of treebank. While several medium- to
large-scale treebanks exist for English (and for other major
languages), pre-existing publicly available resources exhibit the
following limitations: (i) annotation is monostratal, either encoding
topological (phrase structure) or tectogrammatical (dependency)
information, (ii) the depth of linguistic information recorded is
comparatively shallow, (iii) the design and format of linguistic
representation in the tree-bank hard-wires a small, predefined range
of ways in which information can be extracted from the treebank, and
(iv) representations in existing treebanks are static and over the
(often year- or decade-long) evolution of a large-scale treebank tend
to fall behind the development of the field. LinGO Redwoods aims at
the development of a novel treebanking methodology, rich in nature and
dynamic both in the ways linguistic data can be retrieved from the
treebank in varying granularity and in the constant evolution and
regular updating of the treebank itself. Since October 2001, the
project is working to build the foundations for this new type of
treebank, to develop a basic set of tools for treebank construction
and maintenance, and to construct an initial set of 10,000 annotated
trees to be distributed together with the tools under an open-source
license.
This is a presentation of a paper published at COLING 2002, which can

Particle Filters in Robotics
Sebastian Thrun
Carnegie Mellon University
This presentation will introduce the audience to an emerging body
of research on sequential markov chain monte carlo techniques in
robotics. In recent years, particle filters have solved several hard
robotic problems. Early successes were limited to low-dimensional
problems, such as the problem of robot localization in environments
with known maps. More recently, we have begun to exploit structural
properties of robotic domains, to scale particle filters to spaces
with as many as 100,000 dimensions. The presentation will discuss
specific `tricks' necessary to make these statistical techniques work
in robotics, and present robot systems that use particle filters for
real-world perception.
Joint work with Michael Montemerlo (CMU), Daphne Koller and Ben
Wegbreit (Stanford), and Juan Nieto and Eduardo Nebot (Univ. of
Sydney).
About the Speaker: Sebastian Thrun is the Finmeccanica Associate
Professor of Computer Science and Robotics at Carnegie Mellon

Scalable Spoken Dialog Systems
James F. Allen
University of Rochester
http://www.cs.rochester.edu/users/faculty/james/
While there is great interest and activity in building spoken dialogue
systems today, most applications involved very limited domains that
require no significant reasoning. Our goal is to design and build
systems that approach human performance in conversational interaction
in domains that require significant reasoning. We are studying the
class of "Practical dialogues": dialogues in which the conversants are
cooperatively pursuing specific goals or tasks. These include planning
(e.g., designing a kitchen), information retrieval (e.g., finding out
the weather in New York), customer service (e.g., booking an airline
flight), advice-giving (e.g., helping assemble some modular furniture)
or crisis management (e.g., a 911 center assistant). In fact, our
belief is that the class of practical dialogues includes most anything
about which people might want to interact with a computer. While each
of these different genres of tasks require significantly different
reasoning components and have different structures, we believe that we
can develop an generic model of practical dialogue systems that
enables us to build domain-independent components that can relatively
easily be adapted to different domains. I will describe our work so
far and illustrate with examples from some systems we have built over
the past five years.
About the speaker: James F. Allen record is impressive he currently
holds the Dessauer Chair at the University of Rochester and is a
fellow of the AAAI. research interests span a range of issues
covering natural language understanding, discourse, knowledge
representation, common-sense reasoning and planning. A paper about the
current state of AI given at the 1998 AAAI conference can be found
here These areas of research are combined in the TRAINS project, a
long term effort co-directed with Len Schubert. The TRAINS system is
an intelligent planning assistant that can converse in spoken natural
language with a person to create, discuss and evaluate various plans
involving freight shipments by train. In particular, Allen's research
breaks down into two main subareas, broadly classified as research in
discourse and research in plan reasoning.

Constrained Clustering for Improved Pattern Discovery
Sepander Kamvar
Scientific Computing/Computational Mathematics, Stanford
We present an improved method for clustering in the presence of very
limited supervisory information, given as pairwise instance
constraints. By allowing instance-level constraints to have
space-level inductive implications, we are able to successfully
incorporate constraints for a wide range of data set types. Our method
greatly improves on the previously studied COP-K-means algorithm,
generally requiring less than half as many constraints to achieve a
given accuracy on a range of real-world data. We additionally discuss
an active learning algorithm which increases the value of constraints
even further.

GESTURES AND DIALOGUE SEMINAR

Ventura 17
http://www-csli.stanford.edu/events/Gestures/
David. P. Wilkins,
Center for Aphasia and Related Disorders,
V.A. Northern California Health Care System
We are pleased to announce that our first speaker for this Fall
Quarter is David P. Wilkins, from the Center for Aphasia and Related
Disorders, V.A. Northern California Health Care System.
David Wilkins is well known for his research on Australian aboriginal
languages, particularly Arrernte. In several cross-linguistic studies
of gesture he has put forth a compelling case to challenge the notion
that finger pointing is a gestural universal. In this meeting Wilkins
will discuss some of the implications for his research on pointing and
then the floor will be opened for discussion.
Wilkins has expressed a preference to develop his discussion around
the interests of the participants, and has requested that we contact
him by the September 30th, and if possible by September 23rd, with our
queries. For those who intend to participate, please let us know and
we will forward you copies of two of his papers. Upon reading these,
please contact Wilkins with your questions and concerns for him to
address. -Satinder Gill
I attach a possible abstract for the discussion:
David Wilkins:
"I would like to focus the discussion on two general questions:
(1) what is the relation between 'gesture' and 'language'? and,
(2) how can we fruitfully explore this relationship cross-culturally
(using field observations)?
'Pointing' provides a useful starting point for such a discussion for
a couple of reasons. First, most cultures combine some form of
pointing gesture with spatial language to form gesture-speech
composite signals. Still, we know very little about how uniform or
variable such 'composites' are cross-linguistically. (What is the
relation between the information contributed by the gesture, compared
to the information provided in speech?). Second, pointing with the
index finger has long been identified by many researchers as a
gestural universal, reflecting innate predispositions. Is this really
the case? My research with Arrernte-speaking communities in Central
Australia suggests a real need to re-examine what such a claim would
actually mean. My own experience is that, as part of learning to speak
Arrernte, I also had to (re-)learn how to point (and gesture)
properly. I could no longer use my index-finger point in ways that
seemed natural to me, even though 'index finger' pointing is
ubiquitous in the culture. In my presentation, I will use video to
demonstrate some key cross-cultural differences in pointing behavior."

Seven Slides and a Fight:
How Extreme Programming improved our user-centered design process,
but not our social skills
Victoria Bellotti, Nicolas Ducheneaut, Mark Howard and Ian Smith
(PARC)
The subject of this talk is the recent experiences of a small team of
engineers and fieldworkers at PARC of moving from a more conventional
style of user-centered iterative design and prototyping to extreme
programming (XP) as a means to integrate ethnographic fieldwork and
feedback from using prototypes with engineering and design. We
specifically focus on the different perspectives we all have, as user
or customer representatives, designers and engineers, of the pro's and
con's of XP for user-centered design. Normally this causes a fight
about a lot of contentious issues that we have encountered, which we
will be happy to share with you.
About the Speakers: Victoria Bellotti is a Senior Member of Research
Staff in the Computer Science Lab at PARC. She studies current and
prospective technology users trying to understand their work-practice,
their problems and their requirements for future technology. She also
works on analyzing existing or proposed technology design for utility
and usability and on finding ways to improve designs with
user-centered innovations. Victoria studied psychology, ergonomics and
HCI at London University in the UK. After that she worked at Xerox's
Cambridge Research Lab (EuroPARC) for five years. She came to the USA
in 1994 to work in Apple's Advanced Technology Group for three years
before moving back to Xerox to work at PARC in Palo Alto. Her research
interests include Computer Supported Cooperative Work, Computer
Mediated Communication and Ubiquitous Computing.
