ANNOUNCEMENT
Symposium on Computational Approaches to Creativity in Science
Center for the Study of Language and Information
Stanford University, March 29-30, 2008
Creativity manifests in several ways during scientific inquiry.
Investigators often need to carry forward the consequences of
established beliefs, to synthesize theory with measurements, to
explain observed phenomena, and to involve themselves in other
knowledge-driven activities. The computational metaphor provides
powerful tools both for understanding the creative process and for
supporting the environment in which it unfolds. This symposium brings
together philosophers, psychologists, computer scientists, and others
to address questions such as
What role does creativity play in different facets of the
scientific enterprise, and how can computational tools help in
each context?
When does background knowledge aid creativity in science and
when does it interfere with the discovery of creative solutions?
When do interactions among scientists increase creativity and
how can computational aids for interaction support this process?
The speakers will report and discuss their findings on scientific
creativity and the potential for computational creativity-support
tools. For more information about the symposium schedule and
presentations, see
http://cll.stanford.edu/symposia/creativity
The symposium will take place on Saturday, March 29, and Sunday, March
30, just after the AAAI Spring Symposia, at Stanford University's
Center for the Study and Language and Information. Attendance will be
by invitation only, but there will be no registration fee. Fifteen
invited speakers will present their research over two days and we will
have space for a number of non-presenting attendees. If you would like
to attend, please send email to
scacs-08 (at) csli.stanford.edu
with a paragraph describing your interest in scientific creativity and
your past work in relevant areas (e.g., reasoning, learning,
discovery) from the perspective of any discipline.

"Scalable parallel programming with CUDA on manycore GPUs"
John Nickolls
NVIDIA
http://www.nvidia.com/CUDA
The CUDA scalable parallel programming model provides
readily-understood abstractions that free programmers to focus on
efficient parallel algorithms. It uses a hierarchy of thread groups,
shared memory, and barrier synchronization to express fine-grained and
coarse-grained parallelism, using sequential C code for one thread.
Since CUDA was released in 2007, developers have written scalable
parallel programs for a wide range of applications, including
computational chemistry, sparse matrix solvers, sorting, searching,
and physics models. These applications scale transparently to hundreds
of processor cores and thousands of concurrent threads.
NVIDIA GPUs with the new Tesla unified graphics and computing
architecture run CUDA programs, and are widely available in laptops,
PCs, workstations, and servers. The Tesla architecture is massively
multithreaded and scales to over one hundred processor cores.
About the Speaker: John Nickolls is director of architecture at NVIDIA
for GPU computing. He was previously with Broadcom, Silicon Spice, Sun
Microsystems, and was a co-founder of MasPar Computer. His interests
include parallel processing systems, languages, and architectures.
Nickolls has a BS in electrical engineering and computer science from
the University of Illinois, and MS and PhD degrees in electrical
engineering from Stanford University.

"Wireless Sensor Network and How It Enables Greening Computing and Living"
Feng Zhao
Microsoft Research
http://research.microsoft.com/~zhao
Energy is a scarce resource in today's economy. Energy conservation is
limited by our poor visibility into how energy is produced,
distributed, and consumed. I will describe recent work in
instrumenting homes, offices, and data centers so that we can better
account for where the energy goes and optimize for the energy
use. Designing a monitoring and control system of this scale requires
rethinking of the networking, programming, and system management of
sensor network systems.
About the Speaker: About the Speaker: Feng Zhao is a Principal
Researcher at Microsoft Research, where he manages the Networked
Embedded Computing Group. He received a PhD in Electrical Engineering
and Computer Science from MIT. Dr. Zhao was a Principal Scientist at
Xerox PARC and directed PARC's sensor network research effort. He
serves as the founding Editor-In-Chief of ACM Transactions on Sensor
Networks, and has authored or co-authored over 100 technical papers
and books, including a recent book published by Morgan Kaufmann -
Wireless Sensor Networks: An information processing approach (with Leo
Guibas). He has received a number of awards, and his work has been
featured in news media such as BBC World News, BusinessWeek, and
Technology Review.

"AI After Dark: Computers Playing Poker"
Michael Bowling
University of Alberta
The game of poker presents a serious challenge for artificial
intelligence. The game is basically about dealing with uncertainty:
unobservable opponent cards, undetermined future cards, and unknown
opponent strategies. Coping with these uncertainties is critical to
playing at a high-level. In this talk I'll outline both the challenges
and the state of the art in overcoming these challenges. I'll outline
some recent advancements in solving very large extensive games -- four
orders of magnitude larger than traditional techniques. This
technology enabled our programs to play competitively against
professional players in the First Human-Machine Poker Championship
this past summer. With this competition as motivation, I'll also
discuss the critical problem of separating skill from luck in
evaluating poker play. I'll present a general technique for defining
unbiased low-variance estimators in extensive games, and demonstrate
it by analyzing the results of the Human-Machine competition. If time
permits, I'll discuss the future of research in computer poker and
just how close we are to an artificial intelligence that can bring
Phil Helmuth to tears.

"Beyond Web 2.0: You can't divide by zero -- measuring the
effectiveness of free"
Katie Delahaye Paine
The Measurement Standard, KDPaine & Partners
http://www.measuresofsuccess.com/About+Us/Who+we+are/default.aspx
For the past two decades, Katie Paine has been analyzing the media
landscape and helping her clients figure out whether the money they
were spending on marketing and PR was worth it. But now, in the
post-Web 2.0 world where so many tools are free (or virtually so), the
old ROI no longer works. The new ROI is less about quantity and big
numbers, than it is about relationships and conversations. In this
Forum, Katie will discuss how to measure the impact of those "Naked
Conversations" on brand, reputation, and relationships.
About the Speaker: Katie Delahaye Paine is publisher of the first blog
and the first newsletters for marketing and communications
professionals dedicated entirely to measurement and
accountability. Her book, Measuring Public Relationships: the
Data-Driven Communicator's guide to Measuring Public Relationships was
published in December 2007. Prior to launching KDPaine & Partners in
2002, Paine was the founder and president of The Delahaye Group, which
she sold to Medialink in 1999.
For the past 20 years, Paine has been providing professionals with the
tools, data, and information to make better business decisions. Paine
and her colleagues have conducted interviews and analyzed countless
news articles, blogs, newsgroup postings, and internal communications
in the relentless pursuit of quantitative and qualitative measures of
her clients' marketing success. Paine has worked with companies such
as Raytheon, Allstate, Facebook, and Southwest Airlines. Most
recently, she has focused on social media measurement as well as
providing cost-effective measurement programs for non-profits, small
businesses, and government agencies.
Paine's awards and honors include NH Woman Business Owner of the Year
by the Small Business Administration (2007); Entrepreneurial Venture
Creator Person of the Year by the University of New Hampshire (2006);
Business Excellence Award for Excellence in Media & Marketing from New
Hampshire Business Review; and Athena award winner and Board member of
the New Hampshire Political Library. Paine was an initial founder and
former chair of the Institute for Public Relations special commission
and Board member of the New Hampshire Political Library. Paine was an
initial founder and former chair of the Institute for Public Relations
special commission on measurement and evaluation, and she served as
the U.S. liaison to the European Standards Task Force to set
international standards for media evaluation. She writes a regular
column for PR News and contributes to many other publications.

Sam McClure
Psychology, Stanford
Several lines of research in psychology have led to the conclusion

"Analytical Listening through Interactive Visualization"
Elaine Chew and Alexandre François
USC and Radcliffe Institute
This talk introduces the project of our research cluster at the
Radcliffe Institute for Advanced Study. Our goal is to make
discerning listening of music accessible by offering interactive
visualizations of musical structures, captured and analyzed from music
streams in real-time. There are two components to the project: the
mathematical model and algorithms for tonal analysis, and the
underlying software architecture for enabling the real-time
interaction.
Our tonal analysis and visualization system, MuSA.RT, is based on
Chew's Spiral Array model, a geometric model with algorithms to
identify and track evolving tonal contexts. The system displays the
pitches played, and the closest triad and key, as the music piece
unfolds in a performance. The pitch spelling, chord, and key, are
computed by a nearest neighbor search in the spiral array, using two
centers of effect (CEs), which summarize the current short-term and
long-term contexts. The three-dimensional model dances to the rhythm
of the music, spinning smoothly so that the current triad forms the
background for the CE trails.
A challenge of building a system like MuSA.RT is that a human
performer can never play a piece the same way twice. Apart from
natural perturbations in timing from one performance to the next,
expert performers can deliberately use expressive devices, such as
pedaling or tempo variations, to highlight different structures so as
to produce different interpretations of the same piece. A system for
identifying and tracking evolving tonal structures must be robust to,
yet flexible enough to capture, such performance variations.
MuSA.RT was designed using François' Software Architecture for
Immersipresence (SAI), a general formalism for the design, analysis
and implementation of complex software systems. Based on a concurrent
asynchronous processing model, SAI defines primitives and organizing
principles that bridge the disconnect between mathematical models and
natural interaction. From its underlying principles to its graphical
notation and derived tools, SAI embraces a human-centered approach to
the design of computing artifacts.
About the Speaker: Elaine Chew is an Associate Professor of Industrial
and Systems Engineering and of Electrical Engineering at the
University of Southern California (USC) Viterbi School of
Engineering. She was the first honoree of the Viterbi Early Career
Chair. She earned PhD and SM degrees in Operations Research from MIT,
and a BAS in Mathematical and Computational Sciences and Music
Performance from Stanford University. Professor Chew also holds
diplomas and degrees in piano performance from the Trinity College,
London, and Stanford University.
Her research interests center on the computational modeling of music
and its performance. She founded and heads the Music Computation and
Cognition Laboratory at USC, where she conducts and directs research
on music and computing. She received the US National Science
Foundation Career Award and Presidential Early Career Award for
Scientists and Engineers for her research and education activities at
the intersection of music and engineering.
Professor Chew is on the founding editorial boards of the Journal of
Mathematics and Music, the Journal of Music and Meaning, and ACM
Computers in Entertainment. She has served on numerous program
committees for conferences in music and computing; this year, she is
Program Co-Chair for the International Conference on Music Information
Retrieval.
Professor Chew is on sabbatical in 2007-2008, during which she is the
Edward, Frances, and Shirley B. Daniels Fellow at the Radcliffe
Institute for Advanced Study. At Radcliffe, she and her collaborator
Alexandre François form a research cluster on Analytical Listening
through Interactive Visualization.

"Deep Photo and Gigapixel Images"
Johannes Kopf
University of Konstanz
This talk describes two projects in the area of computational
photography that I have recently worked on.
First, I will present a novel method for browsing, enhancing, and
manipulating outdoor photographs by combining them with existing
georeferenced digital terrain and urban models. A simple interactive
registration process is used to align photographs with models. Once
the photograph and the model have been registered, and abundance of
information, such as depth, texture, and GIS data, becomes immediately
available to our system. This information, in turn, enables a variety
of operations, ranging from dehazing and relighting the photograph, to
novel view synthesis, and overlaying with geographic information. I
will describe the implementation of a number of these applications and
discuss possible extensions. Our results show that augmenting
photographs with 3D models in this manner supports a wide variety of
new ways for us to experience and interact with our everyday
snapshots.
In the second part of the talk, I will present a system to capture and
view "Gigapixel Images" (very high resolution, high dynamic range, and
wide angle imagery). I will show how we acquire such images, and then
describe in more details our novel viewer that enables smooth
real-time exploration of such images. Our viewer dynamically and
smoothly interpolates the projection between perspective and curved
projections, and simultaneously modifies the tone-mapping to ensure an
optimal view of the portion of the scene being viewed. I will also
describe how we deal with computational and memory costs when tone
mapping Gigapixel images. In particular, I will show how we use a
joint bilateral upsampling procedure to compute very good full
resolution results from solutions computed at lower resolutions.

"Maintaining Sample Synopsis of Evolving Datasets"
Wolfgang Lehner
Technische Universitat Dresden
Random sampling is an appealing approach to build synopses of large
data sets because random samples can be used for a broad spectrum of
analytical tasks. Current research mainly considers the database
static; in this setting, a sample created once remains valid for its
entire lifetime. In many applications, however, such a static view is
infeasible because it does not take into account the dynamic nature of
the underlying data. In this talk, I will briefly summarize recent
research on the problem of maintaining a random sample of an evolving
dataset. As an example for the challenges of sample maintenance and
the techniques required to solve them, I will discuss the problem of
maintaining a random sample from a sliding window a data stream
defined over a recent time interval. In this setting, the main
challenge is to guarantee an upper bound on the space consumption of
the sample while using the allotted space efficiently at the same
time. The difficulty arises from the fact that the number of items in
the window is unknown in advance and may vary significantly over time,
so that the sampling fraction has to be adjusted dynamically. Within
the talk, I will outline a novel sampling scheme called bounded
priority sampling (BPS), which requires only bounded space and quickly
adapts to changing data

"When computers look at art: Computer vision and image
analysis in humanistic studies of the visual arts"
David G. Stork
Richoh Innovations, Visiting Stanford Computer Science
New computer methods have been used to shed light on a number of
recent controversies in the study of art. For example, computer
fractal analysis has been used in authentication studies of paintings
attributed to Jackson Pollock recently discovered by Alex
Matter. Computer wavelet analysis has been used for attribution of the
contributors in Perugino's Holy Family. An international group of
computer and image scientists is studying the brushstrokes in
paintings by van Gogh for detecting forgeries. Sophisticated computer
analysis of perspective, shading, color and form has shed light on
David Hockney's bold claim that as early as 1420, Renaissance artists
employed optical devices such as concave mirrors to project images
onto their canvases.

"How the languages we speak shape the ways we think"
Lera Boroditsky
Psychology, Stanford University
http://www-psych.stanford.edu/~lera/
How do languages we speak shape the ways we think? Do speakers of
different languages think differently? Does learning new languages
change the way you think? Do bilinguals think differently when
speaking different languages? Does language shape our thinking only
when we're speaking or does it shape our attentional and cognitive
patterns more broadly? In this talk I will describe several lines of
research looking at how speakers of Indonesian, Spanish, Mandarin,
Greek, Kuuk Thaayorre and English talk about and think about events,
causality, and (if there's time) time. The results show that
languages help construct our representations of the world, yielding
predictably different representations in speakers of different
languages.

"Innovation Goes Public"
Bruce Perens
Open Source provides much of the software infrastructure for many of
the world's largest companies and organizations: Merrill Lynch,
Google, Pixar, Amazon, the City of New York, and probably you --
although you might not know it. Innovative products like Linux,
Firefox, and Apache are the market-leaders in their sectors, but there
are tens of thousands of Open Source programs, used for just about
everything. But the economics of Open Source are non-intuitive: how
can you make money by giving software away? Why did IBM de-emphasize
AIX, after spending Billions, in favor of Linux, the product of a
loose collaboration of programmers that it can never control? How can
the world's greatest city trust Open Source to help manage its jails?
Perens will show how Open Source is often the most effective strategy
for creating and utilizing new innovation. He will explain the
economics of Open Source and how it works for profit-generating
companies. His talk will be clear to beginners yet informative even
for Open Source pros.
This talk is co-sponsored by the ATS program, Symbolic Systems and IT
Services.
About the Speaker: Bruce Perens is a leader in the Free Software and
Open Source community. He advises large corporations and several
national governments on Open Source policy. He is creator of the Open
Source Definition, the manifesto of the Open Source movement in
Software. Perens is a vice president at Sourcelabs, a venture-funded
company that provides Open Source services to Wall Street. He is a
visiting researcher at Agder University in Norway, funded by a
national grant. He was HP's first Senior Global Strategist for Linux
and Open Source, and was Senior Research Scientist for Open Source
with George Washington University's Cyber Security Policy Research
Institute. The Bruce Perens' Open Source Series from Prentice Hall
published 24 titles with Perens as series editor. Perens previously
spent 20 years in the computer graphic animation industry, 12 of them
at Pixar Animation Studios. He has a credit on the films A Bug's Life
and Toy Story II.

"Truth in Fiction"
Jean-Pierre Dupuy
French Department
Why is it that for many of us some fictional characters have more
reality and play a more important role in our lives than real persons?
In some extreme cases, it may seem to us that our very life is
inscribed in such or such fiction that has impressed us most.
One thing is certain: you won't find the answers to these disturbing
questions in the seminal paper published by David K. Lewis in 1983,
"Truth in Fiction," which remains the Bible of analytic philosophy
of fiction. Lewis analyzes the kind of convention that binds the
narrator and the reader (or spectator). He admits to the existence of
cases in which the narrator breaks the convention. About those cases,
which represent arguably the essence of literature (or film), Lewis
has, by his own admission, no solution to offer.
The talk will propose a radically different interpretation of truth in
fiction, illustrated by the analysis of Jorge Luis Borges' Fictions,
Camus' The Stranger, Hitchcock's Vertigo, Ian McEwan's Atonement
and a few other classic masterpieces.
The talk will be self-contained, even for those who haven't read or
seen the classics in question. They must promise not to be mad at the
speaker for spoiling their pleasure if, on hearing the talk, they rush
out to buy the books or the DVDs.
About the Speaker: Jean-Pierre Dupuy is Professor of philosophy, Ecole
Polytechnique, Paris, and founding director of C.R.E.A. (Centre de
Recherche en Epistemologie Appliquee), the philosophical research
group of the Ecole Polytechnique, and Full Professor (1/3rd time),
Departments of French and, by courtesy, Political Science, Stanford
University. He is also a Stanford C.S.L.I. Researcher, and is
affiliated with the Stanford Science, Technology, and Society Program,
the Symbolic Systems Forum, the Anthropology Department, and the
Religious Studies Department. He is a member of the French Academy of
Technology.

"Looking at Looking at Looking"
Golan Levin
Carnegie Mellon University
This talk will present a survey of Golan Levin's personal research
into the "medium of response", with consideration given to the
conditions that enable people to experience sustained creative
feedback with reactive systems; to the potential for audiovisual
abstraction to connect viewers to realities beyond language; and more
generally, to information visualization as a mode of art practice. The
talk concludes with a presentation of Levin's most recent attempts to
create engrossing and uncanny interactions structured by gaze: by
endowing responsive artworks with new perceptive capacities -- the
ability to know where we are looking -- and new expressive means,
through simulated eyes that can return and meet our own.
About the Speaker: Golan Levin's work combines equal measures of the
whimsical, the provocative, and the sublime in an exploration of
abstract communication and interactivity. Through performances,
digital artifacts, and responsive environments, Levin applies creative
twists to digital technologies that highlight our relationship with
machines, make visible our ways of interacting with each other, and
explore the potential for non-verbal communication in cybernetic
systems. He is best known for performances and installation works
which generate real-time visualizations of their participants' speech
and gestures, and for interactive information visualizations which
offer new perspectives onto millions of online communications. His
current projects employ interactive robotics and machine vision to
explore the theme of gaze as a primary new mode for human-machine
communication. Levin is Associate Professor of Electronic Time-Based
Art at Carnegie Mellon University, where he also holds Courtesy
Appointments in the School of Computer Science and the School of
Design.

"Designing Appropriate Computing Technologies
for the Rural Developing World"
Tapan Parikh
http://www.ischool.berkeley.edu/about/news/topstories/parikh20070815
People living in the rural developing world have many information
needs that could, but are not, being met by information technology.
Technologies for this context must be low-cost, accessible to diverse
populations and appropriate for the local infrastructure, including
conditions of intermittent power and connectivity.
In this talk, drawing from the results of an extended design study
conducted with microfinance group members in rural India (many of whom
were semi-literate or illiterate), I outline a set of user interface
design guidelines for accessibility to such users. The results are
used to motivate the design of CAM, a mobile phone application toolkit
including support for paper-based interaction; multimedia input and
output; and disconnected operation. Through ekgaon technologies, a
company that I co-founded, over 10,000 microfinance group members in
India are now using CAM to maintain their monthly records. In Mexico,
we are conducting a pilot where over 1,000 small coffee farmers will
use CAM to document their compliance with organic certification
requirements. I will also discuss some of the more recent directions I
have been pursuing in collaboration with my students -- including
building mobile tools to improve the standard of health care delivery
in sub-Saharan Africa, and designing farmer-centric information
systems linking farmers to premium markets in South Asia.
About the Speaker: Tapan Parikh joined the faculty of the School of
Information this semester.

"Enabling Mobile 2.0: Data Management for User-Generated Services"
Christian Jensen
Aalborg University
Having recovered from the dot-com crash of the early 2000's, the
Internet now features an abundance of new, innovative technologies and
services. We are witnessing the rapid emergence of a communication and
computing infrastructure that enables the Internet to go mobile.
Indications are that the mobile Internet will be "bigger" than the
conventional Internet.
This talk describes the background, status, and goals of an ongoing
research project and evolving middleware system, called Streamspin,
that supports data management aspects of innovative mobile Internet
services, including push-based and context-aware services. Streamspin
aims to power sites that enable users to create and share services,
and that are capable of delivering services to millions of concurrent
users.
The talk briefly covers two geo-context services that are being
integrated into the system. The first aims to enable users to build
services that rely on the tracking of the continuously changing
positions of populations of mobile-service users. The second aims to
extend the geo-context of a user to include not only the user's
current location, but also the user's (anticipated) destination and
route towards that destination.
