FUNDING OPPORTUNITY
CSLI-Edinburgh Link: Call for Proposals
As you probably know, substantial funding has been secured from
Scottish Enterprise for collaboration between Edinburgh University's
HCRC (Human Communication Research Center) and Stanford's CSLI,
directed to the area of speech and language processing technologies
and related areas. There are 9 projects already running (see the
portfolio at http://www.hcrc.ed.ac.uk/stanford/ ), and we are now
seeking to start a second round. Levels of support can be
substantial. (Several current projects have budgets around $500,000
plus indirect costs over three years. This figure could be exceeded.)
Support can be provided for a range of activities in research and
training. Details of these, eligibility criteria, and how to apply,
are given in the Call for Proposals and supporting documentation, now
available at
http://www.hcrc.ed.ac.uk/stanford/rfp.pdf
(there is currently no HTML version).
Note that the initial deadline for Outline Proposals is 27th June 2003.
This funding has a number of attached conditions and responsibilities,
due to its origin from an economic development agency. These concern
especially IP, exploitation and publication. Also, in this round, we
are especially hoping for proposals that have relatively immediate
commercial relevance, and perhaps collaboration.
If you have any questions, feel free either to contact Keith Devlin or
go directly to the Edinburgh-Stanford Link Coordinator: John Lee,
J.Lee@ed.ac.uk.

"Unwrapping 2-D Phase Images Using the Sum-Product Algorithm
and
A Variational Technique for Separating Speech Sources Using Fewer
Microphones than Speakers"
Brendan Frey
University of Toronto
Many types of coherent imaging systems, including MRI and INSAR make
measurements on a 2-D grid, but the measurements are taken modulus a
known constant. Given such a "phase image", the goal of phase
unwrapping is to infer the original, unwrapped values from the wrapped
values, using prior knowledge about the smoothness of the image. One
approach to solving this problem is to infer the gradient vector field
o the unwrapped image and then integrate the gradient field. The
gradient in a particular direction at a pixel is equal to the observed
pixel difference plus an unknown integer number of shifts. We
introduce a technique for inferring these shifts using the sum-product
algorithm, applied in a graphical model that prefers shifts that match
the phase image and that constrains the shifts to satisfy properties
of a gradient field. We show that the technique performs better than
standard techniques for phase unwrapping, which is why MERL is
implementing it in hardware to perform phase unwrapping in real-time.
(Joint work with R. Koetter, N. Petrovic and D. Munson, Jr.)
We show how a variational technique can be used in conjunction with
time delay information to separate speech sources using a microphone
array. Models of the speech sources are learned, so some degree of
separation is possible even when the number of sources is less than
the number of microphones. Exact inference in the model is
intractable, because all possible combinations of the state spaces of
the speakers should be examined to see which combinations match the
microphone signals the best. We use a factorized variational
approximation to the posterior, to make inference and learning
tractable. (Joint work with S. Rennie, P. Aarabi, T. Kristjansson and
K. Achan, University of Toronto.)

"Finding needles in a terabyte haystack
How Google searches the web"
Urs Hoelzle
Google Inc.
Search is one of the most popular activities on the internet, and is
only becoming more so as the web grows in both size and popularity. In
this talk I'll discuss how we do search at Google; the issues involved
in making a good search engine; the hardware system, involving tens of
thousands of low-cost, commodity PCs; and the software needed to tie
it all together.
About the speaker: Urs Hoelzle joined Google from the University of
California, Santa Barbara where he was an associate professor of
computer science. In 1994, he earned a Ph.D. from Stanford
University, where his research focused on programming languages and
their efficient implementation.
As one of the pioneers of "just-in-time compilation," Hoelzle invented
fundamental techniques used in most of today's leading Java
compilers. Before joining Google, Hoelzle was a co-founder of
Animorphic Systems, which developed compilers for Smalltalk and
Java. After Sun Microsystems acquired Animorphic Systems in 1997,
Hoelzle helped build Javasoft's high-performance Hotspot Java
compiler.
As the company's first vice president of Engineering, Hoelzle led
development of the Google's software and hardware infrastructure
during its first two years and was renowned for both his red socks and
his free-range Leonberger, Yoshka (Google's top dog).

Distributed teams are the core building block of knowledge-based
entities. This trend is largely driven by technological intensity,
globalization, and the rise of a new generation of knowledge
workers. Distributed teams pose a range of unique leadership and
communication challenges. Their effective deployment requires novel
recipes and implementation guidelines. This session focuses on
profiles of distributed teams and effective strategies for guiding and
leading knowledge workers in virtual team settings.
About the Speaker: Dr. Homa Bahrami is an international educator,
author and advisor, specializing in knowledge workers and
knowledge-based organizations. She is a Senior Lecturer at the Haas
School of Business, University of California, Berkeley, where she
teaches her MBA & executive courses on organizing for strategic
advantage, and leading high tech knowledge workers. She is the
co-author of a leading textbook entitled "Managerial Psychology:
Managing Behavior in Organizations," published by the University of
Chicago Press, and translated into many languages. Her research
findings on organizational and leadership trends in the high
technology arena have been published in leading journals. She advises
senior executive teams on organizational design challenges, and is
active in designing and teaching executive development programs in the
US, Europe, and Asia-Pacific.. She is a member of the International
Academy of Management, and serves on the advisory boards of several
technology companies in Silicon Valley and Europe.

"Dialogue Act Tagging With Unlabeled Data?"
Anand Venkataraman
Speech Technology and Research Laboratory, SRI International
Labeling utterances with their dialogue act category (such as
Question, Answer, Back-channel, etc.) is an important step toward
speech understanding, yet training such taggers usually requires large
amounts of data labeled by linguistic experts. We investigated the use
of unlabeled data for training HMM-based dialog act taggers. Three
techniques were found to be effective for bootstrapping a tagger from
very small amounts of labeled data:
1. iterative relabeling and retraining on unlabeled data;
2. a dialog grammar to model dialog act context, and
3. a model of the prosodic correlates of dialog acts.
On the SPINE dialog corpus, the combined use of prosodic information
and unlabeled data reduces the tagging error between 12% and 16%,
compared to baseline systems using word information only.
In this talk, I will describe the principles behind the technique, the
framework used to test them and experimental results on the SPINE
corpus.
This is joint work with Luciana Ferrer, Andreas Stolcke, and Liz
Shriberg.

"Fluid Content, Fixed Form:
Symbolic Representations of Music as Intellectual Property"
Eleanor Selfridge-Field
Music Department, Stanford University
Music is among the most chameleon of subjects for consideration as
intellectual property. In the analog world, music is usually
considered to consist of a continuous stream of sound. Abstract views
of music are based on other sensory processes=97vision in the case of
notation, structured listening and reasoning in the case of cognitive
activities, such as theorizing and analyzing. In the digital world,
musical information is conveyed (even when perceived as a sound
stream) in some kind of symbolic form. Some symbolic systems of
representation are designed to be humanly comprehensible, others are
designed to be inscrutable.
There is no universal system either for representing music or for
interchanging data employing different symbol sets. Mere difference of
scheme matters very little in the realm of intellectual property, but
the fact that no two systems of representation privilege the same
elements of music or weight them in the same way allows for subtle
differences in multiple representations of the same work. In artistic
terms, one can draw a different picture of any given work at every
sitting.
This fluidity of both representation and abstraction bodes ill for the
primary distinction made under US copyright law between 'the work
itself' and the fixed form in which it is copyrighted. Music is an art
of fluidity and the digital revolution is making it more apparent
every day that that the notion of fixing =93the work itself=94 is more
amenable to theory than to practice. These challenges will be
discussed in this talk.

"Antipalatalization as a systemic effect"
Junko Ito and Armin Mester
University of California, Santa Cruz
This paper explores the development of sibilants and front glides
before front vowels in the historical phonology of Japanese. The
guiding idea is that wellformedness in this and many other similar
cases can be understood only with reference to the larger system of
contrasts a form enters into. In OT, this is captured by constraints
requiring that contrasts be maintained, and that they be perceptually
distinct (as argued in work by Flemming and Padgett, building on
earlier ideas and proposals by de Saussure, Martinet, Lindblom, and
others).

"Ockham's Razor and Kolmogorov complexity theory".
Ben Escoto
Philosophy, Stanford
In a recent textbook, Vitanyi and Li argue that Kolmogorov complexity
theory can
1) define simplicity in a relatively language neutral way, so that an
object's simplicity is an intrinsic feature of it, and
2) show that simple theories predict more accurately than complex
theories.
In my talk I argue against these claims.

"Peephole Displays:
Pen Interaction on Spatially Aware Handheld Computers"
Ka-Ping Yee
UC Berkeley Computer Science
http://zesty.ca/
Peephole Displays are pen-operated handheld computers that track their
own position in order to provide a movable window on a virtual
workspace. Previous research has explored various ways of using
spatially tracked displays, in particular as windows onto 3-D virtual
realities. This work is a bit different in that it looks at combining
pen input with spatial tracking, and borrows manipulation techniques
from familiar 2-D displays.
With a Peephole Display, you can use both hands together: the hand
holding the display can navigate through information, and the hand
holding the pen can manipulate that information. Thus, you can
navigate and manipulate simultaneously, without interrupting the flow
of work. It's also possible to manipulate objects larger than the
screen more easily using Peephole techniques. Peephole displays also
enable a few totally new kinds of interaction, such as 3-D
drag-and-drop.
In this talk, I'll describe and illustrate the Peephole concept, and
show a video demonstration of some applications that take advantage of
Peephole interaction techniques. I'll also describe the results of a
user study to assess the feasibility of these techniques for PDAs, and
show some more speculative ideas on future possibilities.
About the speaker: Ka-Ping Yee is a Ph. D. student in Computer Science
at UC Berkeley specializing in HCI. He has previously worked at
Alias|Wavefront, Xerox PARC, Industrial Light and Magic, and Opera
Software, and has participated in the development of the Python
programming language. His research interests include critical
discussion, information visualization, capability-based security, and
secure interaction design.

"SHRUTI-Agent: A Structured Connectionist Agent Architecture"
Carter Wendelken
UC-Berkeley and International Computer Science Institute
One of the great scientific challenges of today is to understand how
complex cognitive processes such as inference and decision-making can
be achieved by the human brain. The incredible complexity of the brain
makes computational modeling an indispensable tool to meet this
challenge. Connectionist models that explain cognition in terms of
brain-like structures and mechanisms are particularly useful in this
endeavor. In this talk I describe SHRUTI-agent, a neurally motivated,
structured connectionist agent architecture that is capable of
inference, decision-making, and interaction with a simulated
environment. SHRUTI-agent is an extension of SHRUTI, a connectionist
model that demonstrates how temporal synchrony variable binding in
conjunction with structured representations can support several
aspects of high-level cognition. Creating a decision-making agent
architecture based on SHRUTI involved a number of enhancements and
additions to the model, and these comprise the primary contributions
of the thesis.
First, in order to build a system capable of effective reactive
decision-making, it was necessary both to enhance the evidential
reasoning capabilities of the SHRUTI model and to develop compatible
connectionist structures and mechanisms to manipulate utility.
Second, in order to enable the system to handle complex or sequential
decision problems, a set of control mechanisms was developed. It is
shown that the complex control mechanisms required for decision-making
(e.g. hypothesis-testing) can be based on combinations of simple
control primitives such as monitoring, filtering, and maintenance.
Each of these control primitives is described in terms of its
connectionist realization.
Third, consideration of the impact of learning on decision-making
performance led to some preliminary work aimed at understanding how
SHRUTI's structured representations can be learned. Utile concept
learning is introduced as a mechanism for recruitment of new concepts
and rules that lead to improved decision-making performance.

"Distributed Networked Sensing and Information Processing"
Feng Zhao
Palo Alto Research Center
I will describe PARC's recent work in distributed networked sensing
and applications. Wireless sensor networks are emerging as a
technology solution for a number of societal problems (transportation,
manufacturing, healthcare), and are a rich source of research issues
in communication protocols, sensor tasking and control, data fusion,
distributed databases, probabilistic reasoning, and algorithmic
design. At PARC, we have been developing an architecture and
algorithms to enable distributed sensors (or agents) to
collaboratively seek, process, and aggregate information in a
resource-constrained environment. I will describe our IDSQ sensing and
routing algorithms, group management protocols, feather weight
tracking methods, and TinyGALS programming model. Experimental results
on several PARC sensor network testbeds will also be demonstrated.
About the Speaker: Feng Zhao is a Principal Scientist and directs the
Embedded Collaborative Computing Area in the Systems and Practices
Laboratory at PARC. He is also Consulting Associate Professor of
Computer Science at Stanford. The two main projects in his group,
Collaborative Sensing and Smart Matter Diagnostics, investigate how
MEMS sensor and networking technology can change the way we build and

"Form, Function, and Punky Color #34:
The Gunn High School Robotics Team"
The Gunn High School Robotics Team
What results from mixing 50 high school students, 8 adult mentors, 1
machine shop, a box full of motors and electronics, and innumerable
cans of red hair dye?
A life changing experience! Come hear the members of the Gunn Robotics
Team recall the successes and failures associated with designing a
130-pound remote controlled robot in only six weeks. See the
student-built G-Force 2003 in action, along with student-produced
videos and this year's award winning 30-second computer animation.
Come witness the difference PARC has helped make in the community by
sponsoring and mentoring this motivated group of students.
The Gunn Robotics Team was started in 1997 by Gunn High School teacher
Mr. Bill Dunbar. Since its inception as an 8-member club, it has grown
into a 50-member organization that is one of the most popular programs
on campus. Each year, the team participates in the FIRST Robotics
Competition, an international high school robotics challenge that
gives students six weeks to build a 130-pound remote controlled robot
to be pitted against other high school teams in both regional and
national competitions.

"Image/surface inpainting and camouflage: Do not believe what you see"
Guillermo Sapiro
University of Minnesota
Inpainting is the art of modifying and image in a form that is not
detectable to an ordinary observer. The applications of this are
numerous, from special effects in movies to wireless image
transmission. In this talk we will describe novel algorithms for image
inpainting that we have been developing in the last few years. The
algorithms are based on partial differential equation such as those
used to model fluids. We will show how we can simultaneously
reconstruct structured and textured regions, show extensions to 3D
surface, and present numerous examples in special effects, image
reconstruction (from family photos to the Venus mission), image
compression and transmission, and 3D art reconstruction. We will also
talk about the connections of our algorithms with biological
processes.
About the Speaker: Guillermo Sapiro was born in Montevideo, Uruguay,
on April 3, 1966. He received his B.Sc. (summa cum laude), M.Sc., and
Ph.D. from the Department of Electrical Engineering at the Technion,

"How Language Structures Concepts"
Len Talmy
Department of Linguistics, SUNY Buffalo
As a fundamental design feature, language has two subsystems, the
open-class (lexical) and the closed-class (grammatical). These
subsystems perform complementary functions. In the total meaning
expressed by any portion of discourse, the open-class forms contribute
the majority of the content, while the closed-class forms determine
the majority of the structure. Further, across languages, all
closed-class forms are under great semantic constraint: They represent
only certain concepts and categories of concepts, but not
others. Closed-class representations accordingly appear to constitute
the fundamental conceptual structuring system of language. This talk
will examine some of the main conceptual categories and member
concepts represented by closed-class forms; the properties that
distinguish such closed-class representations from open-class
representations; and the conceptual structuring function performed by
this organization of language. This linguistic structure will be
brought into relief by contrasting it with the structure found in
another cognitive system, visual perception. It will be seen that
language and vision, along with other cognitive systems, each have
certain structural properties of their own and others that they share,
in what I term the overlapping systems model of cognitive
organization.
About the speaker: Leonard Talmy is the Director of the Center for
Cognitive Science, Professor of Linguistics, and Adjunct Professor of
Philosophy at the University at Buffalo, State University of New
York. He received his Ph.D. in Linguistics at the University of
California, Berkeley. Since then, he has taught in Hamburg, Rome, and
Moscow (the latter two as a Fulbright Fellow) and at Stanford,
Georgetown and UC Berkeley. He has done extended research at Stanford
on the Language Universals Project, at the UCLA Neuropsychiatric
Institute with language-impaired children, and at the University of
California at San Diego in cognitive science at the Center for Human
Information Processing. And he was the Coordinator of the Cognitive
Science Program at the University of California at Berkeley for six
years. His broader research interests cover cognitive linguistics, the
properties of conceptual organization, and cognitive theory. His more
specific interests within linguistics center on natural-language
semantics, including: typologies and universals of semantic structure;
the relationship between semantic structure and formal linguistic
structures -- lexical, morphological, and syntactic; and the relation
of this material to diachrony, discourse, development, impairment, and
culture. Additional specializations are in American Indian and
Yiddish linguistics. He is the author of a two-volume set with MIT
Press (2000): Toward a Cognitive Semantics -- volume 1: Concept
Structuring Systems; volume 2: Typology and Process in Concept
Structuring. Previously published articles include "The Relation of
Grammar to Cognition", "Force Dynamics in Language and Cognition",

"The DIVER Project:
Point-of-View Authoring of Virtual Tours of Video Recordings
(aka "Diving") for Learning, Education and Other Purposes"
Roy Pea and Michael Mills
Stanford Center for Innovations in Learning
DIVER (Digital Video Exploration and Reflection) is a research and
development project of Stanford's Center for Innovations in Learning
that is devoted to creating tools for enhancing the activities of
exploring and reflecting on digital video records, captured on devices
from consumer videocameras to high-end panoramic videorecorders. The
National Science Foundation funded project includes 360-degree
panoramic audio-video capture, authoring, and interaction where one
can create virtual pathways through video content and annotate them
for sharing and commentary via web pages. These DIVER functionalities
support "guided noticing" as an instructional method (e.g., in teacher
education, graduate research training), and in collaborative
researcher analyses of videorecords and hold promise for entertainment
and commerce. Core objectives of DIVER are to enable "virtual
videography" and to allow video users to "capture once, and author
forever". The DIVER project aspires to accelerate cultural
appropriation of video as a fluid expressive medium for generating,
sharing and critiquing different perspectives on the same richly
recorded events and to work with others to provide a Digital Video
Collaboratory that enables cumulative knowledge building from
video-as-data for discovery and commentary. DIVER is designed so as to
provide an integrated platform for digital video recording,
annotation, management, transcoding, distribution, and collaboration.
About the Speakers: Roy Pea is Professor of Education and Learning
Sciences at Stanford University, Co-Director of the Stanford Center
for Innovations in Learning (SCIL, http://scil.stanford.edu), and has
extensive experience in applying video analysis technology to studies
in the learning sciences and technology design. He is Fellow of the
National Academy of Education, American Psychological Society, and the
Center for Advanced Study in the Behavioral Sciences. He is co-founder
of Teachscape.com.
Michael Mills is SCIL's design director, and a cognitive scientist
with 17 years experience in interface, product and interface design,
user studies, and teaching. While serving as principal scientist at
Apple Computer, he was instrumental in the development of QuickTime
and QuickTimeVR. He holds several interface design patents in digital
video, and has authored many articles on interface design..

"Informally Prototyping Multimodal, Multidevice User Interfaces"
Anoop Sinha
Group for User Interface Research (EECS Department)
Increasingly, it is important to look at the end-users tool of the
future as not a solitary PC, but as a diverse set of devices, ranging
from laptops to PDA's to tablet computers. Some of these devices do
not have keyboard and mouse, and thus multimodal interaction
techniques, such as pen input and speech input, will be required to
interface with them. Interaction designers are increasingly faced with
the challenge of creating interfaces that target this style of
interface. Our study into their interface design practice uncovered
the lack of processes and tools to help them.
This dissertation covers the motivation, design, and development of
CrossWeaver, a tool for helping these designers prototype multimodal,
multidevice user interfaces. This tool embodies the informal
prototyping paradigm, leaving design representations in an informal,
sketched form and creating a working prototype from these sketches.
Informal prototypes created with CrossWeaver can run across multiple
standalone devices simultaneously, processing multimodal input from
each one. CrossWeaver captures all of the user interaction when
running a test of a prototype. This input log can quickly be viewed
for the details of the users multimodal interaction, and it can be
replayed across all participating devices, giving the designer
information to help him or her iterate the interface design. Our
evaluation of CrossWeaver with professional designers has shown that
we have created an effective tool for early creative design of
multimodal, multidevice user interfaces. CrossWeaver dovetails with
existing design processes and can assist in a number of current design
challenges.

"Equatives and Deferred Reference"
Gregory Ward
Northwestern University
One of the most creative, but least understood, features of colloquial
discourse is the possibility of deferred reference (Nunberg 1979,
1955): the use of an expression to refer to an entity not denoted by
the conventional meaning of that expression. Consider the examples in
(1), uttered in the context of a luncheonette:
(1) a. [server to co-worker] The ham sandwich left me a big tip.
b. [customer to server holding a tray full of orders] I'm the ham
sandwich.
In (1a), the speaker's reference is `deferred' in the sense that he is
referring indirectly to the person who ordered the ham sandwich via
the ham sandwich itself. With the equative copular sentence in (1b),
on the other hand, the speaker is `equating' herself with her order to
convey indirectly that she is the ham sandwich orderer. In the spirit
of Nunberg (1979), I refer to such equatives as deferred equatives. In
this paper, I present arguments against previous accounts and provide
a new theory of deferred reference to accommodate examples like those
in (1). Specifically, I will be arguing against the notion of meaning
transfer and in favor of the notion of reference mapping. I claim that
felicitous use of both deferred equatives and deferred non-equatives
requires the presence of a contextually salient correspondence, or
mapping, to hold between sets of relevant discourse entities. In (1),
the relevant mapping is between the (inferred) set of deli customers
and the (evoked) set of their orders. In addition, the use of a
deferred equative requires the presence of a contextually licensed
open proposition (OP) that explicitly encodes the reference mapping.
Finally, I present the results of an empirical study (Ward & Tilsen
2002) in which subjects were asked to rate various kinds of deferred
equatives.

BECOMING HUMAN CONFERENCE
The Evolutionary Origins of Religious, Spiritual and Moral Awareness

Building 320, Room 105
http://www.metanexus.net/becoming_human/c2info.html
Year Two:
From Biology to Biography: The Science of the Human Person
The rise of evolutionary theory as the unifying principle in the human
sciences creates a challenging dilemma for our understanding of the
spiritual, religious and moral dimensions of human existence.
Evolution provides an explanation of the development of life within
the frame of biological utility, yet it has produced a species with a
sense of purpose, and whose moral imperatives claim authority from a
transcendent source.
An interdisciplinary effort has been under way to investigate the
origins of mind, the evolutionary importance of consciousness, and the
adaptive role of culturally generated narratives that convey human
meaning and purpose within a larger explanation and interpretation of
life. This conference brings together thinkers from diverse fields to
investigate this crucial junction of the sciences and the humanities.
Sponsored by the John Templeton Foundation and Stanford University

Sciences).
