"Model-Driven Software Verification"
Gerard J. Holzmann
NASA/JPL Laboratory for Reliable Software
http://spinroot.com/gerard/
http://eis.jpl.nasa.gov/lars/
The current focus in logic model checking in software verification
targets the elimination of the need for hand-constructed models. In
the FeaVer project we used automated model extraction from C code to
address this problem. In this talk I will describe a new, and possibly
simpler, method, that allows us to link a logic model checker (e.g.,
Spin) directly to unmodified application level code. We now write a
non-deterministic test-harness as a Spin model, to drive the
application through all its relevant states, while the model checker
verifies its logic properties. Notably, the model checker can use
powerful data abstraction techniques in this verification process,
while the application uses only concrete data representations. I'll
give some examples of the application of this method to the
verification of critical pieces of flight software for a recent JPL
mission.
About the speaker: Dr. Gerard J. Holzmann is perhaps best known as the
designer of the Spin model checker, which was recognized in 2001 with
the ACM Software Systems Award. Formerly a Director of the Computing
Principles Research group at Bell Labs in Murray Hill, NJ, Holzmann
joined NASA's Jet Propulsion Laboratory in 2003 to start a new
Laboratory for Reliable Software. Holzmann holds 7 patents, one of
which received the 2003 Thomas Alva Edison Award in Information
Technology from the Research and Development Council of New Jersey. He
has written several books, including "The Spin Model Checker"
(Addison-Wesley, 2004), "The Early History of Data Networks" (IEEE CS
Press, 1995), and "Beyond Photography: The Digital Darkroom" (Prentice
Hall, 1987).

"Event Categorization in Adult and Child Language:
The case of 'cutting' and 'breaking'"
Melissa Bowerman
Max Planck Nijmegen
To be able to talk about their experiences, speakers have to parse the
ongoing perceptual flow into units and categorize these units as
instances of recurrent event types such as `running' or `breaking
something'. Do the verbs of different languages group and distinguish
events in largely the same way, perhaps due to biases in human
nonlinguistic event cognition or to clustering of event features in
the real world? Or do languages partition events in an infinite number
of crosscutting ways? How do children arrive at the event categories
their language requires? These questions can be explored by asking
speakers of a range of genetically and areally diverse languages to
describe standardized sets of events, and then comparing their
responses with the help of multivariate statistics in search of
universal, language-specific, and age-related patterns in the semantic
structuring of the domain. I illustrate this approach with results
from two ongoing Max Planck group projects on the categorization of
events that have played an important role in lexical semantic
theorizing -- 'cutting' and 'breaking', and consider implications of
fine-grained language variability for the semantic representation of
predicate meaning.

"Similar Preferences"
Ha Vu
Information and Decision Technologies, Honeywell International
Do you prefer Leno to Letterman? Pat Metheny to Kenny G? Basketball to
Baseball? Jodie Foster to Demi Moore? If you answer ``yes'' to all of
these questions, you probably have preferences very similar to mine.
But exactly how similar? How can we define and measure similarity of
preferences, given limited available information? In this talk I will
discuss my experiences in attempting to answer this question. Along
the way, I will show how decision theory, collaborative filtering,
case-based reasoning, Markov chain Monte Carlo simulation, and kernel
methods all have a little something to help me in this effort.
About the Speaker: Vu Ha is currently a research scientist at
Honeywell's Information and Decision Technology Center in Minneapolis,
MN. His main research interest is automated decision making, and his
dissertation addresses issues that arise in representing, eliciting,
and reasoning with incomplete preferences. He is also interested in
probabilistic reasoning and statistical machine learning. Vu Ha
obtained a Ph.D. in computer science from the University of
Wisconsin-Milwaukee, and B.S. and M.S. degrees in computer science
respectively from Kossuth University and Eotvos University in
Hungary. At the age of fifteen, he earned a gold medal at the
International Mathematics Olympiad in Warsaw, Poland.

"Rate Control in Random Access Networks"
Peter Marbach
University of Toronto
Rate control is one of the most important problems in computer
networks. If input rates to a network are left uncontrolled, then the
offered load may exceed the network capacity causing congestion,
buffers fill up and packets have to be dropped. It is well known that
network congestion has a negative impact on performance, and can
potentially lead to a throughput collapse. Rate control for
point-to-point (wide area) networks has been extensively studied and
is well understood by now. Currently, the Internet uses TCP to
control input rates; however TCP has some well-known
drawbacks. Recently, ``price-based'' rate control schemes have
recently received considerable attention. In this approach, congestion
(price) signals which depend on the load at individual links is used
to modulate the transmission rates of traffic sources. Price-based
schemes overcome many of the drawbacks of TCP. Surprisingly, little
attention has been paid to rate control for local area networks,
arguably less to end-to-end rate control for networks comprising both
wide area and local area networks. In the talk, we consider a rate
control scheme for local area networks that support the CSMA-family of
random access protocols and discuss how it can be integrated with
price-based rate control for point-to-point network to provide
end-to-end rate control.
About the Speaker: Peter Marbach was born in Lucerne, Switzerland. He
received the Eidg. Dipl. El.-Ing. (1993) from the ETH Zurich,
Switzerland, the M.S. (1994) in electrical engineering from the
Columbia University, NY, U.S.A, and the Ph.D. (1998) in electrical
engineering from the Massachusetts Institute of Technology, Cambridge,
Massachusetts, U.S.A. He joined in 2000 the Computer Science
Department at the University of Toronto as an assistant professor. He
has also been a Post-Doctoral Research Fellow at the Center for
Communication Systems Research, University of Cambridge, UK, and a
visiting scientist at the Siemens Corporate Research Center in
Munich. Peter Marbach has received the IEEE INFOCOM 2002 Best Paper
Award for his paper "Priority Service and Max-Min Fairness". His
research interests are in the fields of communication networks,
stochastic systems, optimization, and control.

"Applications of DNA Microarrays
to Biomedical Research and Molecular Diagnostics"
Steve Laderman
R & D Dept Manager, Molecular Diagnostics, Agilent Labs
Applications of modern, high-throughput, highly multiplexed
bio-molecular measurement systems to the analysis of complex diseases
are leading to the discovery of characteristic molecular phenotypes
and associated genotypes that correlate to disease pre-disposition,
clinical symptoms, and responses to therapy. Such discoveries both
accelerate the invention and development of new therapies and reveal
potential strategies for increasing the precision and timeliness of
diagnostic methods. To create and optimize diagnostic methods that
emerge from such studies, it is essential to establish the precise
information content required. The search for such parameters in this
rapidly evolving field at the interface of biology, chemistry,
physics, mathematics, computer science, and engineering is greatly
aided by high quality, robust, and flexible measurement systems along
with computation tools that emphasize transparent and efficient
algorithms. Insights obtained in this way directly contribute to
extension and refinement of the methods themselves, creating
additional needs and opportunities for advances.
About the Speaker: Dr. Laderman manages Agilent Laboratories'
Molecular Diagnostics Department, dedicated to molecular biology,
biochemistry, computational biology, and engineering for the
development genetic, genomic, and proteomic analysis systems for
biomedical research and molecular diagnostics. He graduated from
Wesleyan University with a B.A. in physics, and from Stanford
University with a Ph.D. in Materials Science & Engineering.

"Value Driven Agents and the 'Be all you can be' Guarantee"
Daniel Shapiro
ISLE and CSLI
Why don't we live in smart houses that automatically brew our coffee
in the morning, and play our favorite music at night? Why don't we
drive on automated freeways that get us there faster, even in rush
hour? Why won't NASA let the Mars rover avoid rocks on its own? Rather
than blame an absence of technology, I treat the issue as a lack of
trust due to poor communication. In this view, the goal is to give an
agent a better appreciation of its user's values, so that its choices
won't have unintended effects.
This talk will introduce a framework for constructing Value Driven
Agents that are guaranteed to maximally please their users within the
limitations of their given skills. I will begin by introducing the
concept of user-agent value alignment, and then outline a design
methodology and an implementation model for creating Value Driven
Agents of this kind.
About the Speaker: Dr. Daniel Shapiro is a Senior Researcher at
Stanford's Center for the Study of Language and Information and the
Assistant Director of the Institute for the Study of Learning and
Expertise. Dr. Shapiro's current research interests focus on the
design, development, and application of autonomous agents that are
motivated by a core concept of value, as well as on the underlying
technologies of decision theory, reactive computing, and reinforcement
learning.

Is there much point doing research on symbolic Machine Translation
(MT) in the 21st century? Can one combine LFG and HPSG in a single
end-to-end system? Yes, but ... I will provide a project overview on
the Norwegian national initiative LOGON, which aims to deliver
high-quality, document-level Norwegian -- English MT based on the
combination of a symbolic, semantic-transfer-oriented backbone and
stochastic processes for ambiguity management and robustness. The
project implements a relatively conventional translation pipeline,
with Norwegian LFG analysis, semantic transfer, and grammar-based
generation (using the LinGO English Resource Grammar) as its three
core phases. Components communicate in a uniform, underspecified,
flat meaning representation language: Minimal Recursion Semantics
(MRS). Following a high-level overview, i will review a few novel
aspects of MRS-based transfer and issues of efficiency and ambiguity
management in transfer and generation.

"The Evolution of Syntax in Wittgenstein's Philosophy"
Angela Potochnik
Stanford
I will examine the shift in Ludwig Wittgenstein's position regarding
the nature and status of logical truth from the Tractatus to the early
1930s, when he was in conversation with Friedrich Waismann and Moritz
Schlick of the Vienna Circle. In the Tractatus, logical truths are
merely tautologous propositions. By 1930, though, Wittgenstein had
significantly expanded his notion of logical truth to include the
relations among senses of words. This changed position regarding the
nature of logical truth seems to force a change in the status accorded
to these truths. Thus the question is raised for Wittgenstein as to
whether logical truth and the syntax comprised thereof is a matter of
convention. In the Tractatus, syntax is far from conventional; logical
truth shows the formal structure of the world. Yet a much-expanded
notion of logical truth brings with it the possibility of different
syntaxes, which in turn raises the question of how syntax is
determined. Given the nature of Wittgenstein's views at the time,
convention seems the natural answer. Characteristically, his remarks
fail to settle the issue explicitly, but they are, of course,
extremely suggestive. He has certainly moved toward conventionalism
since the Tractatus, but at least in some moods he seems hesitant to
embrace a full-blown conventionalism. I suggest that his position
might be seen as an unwillingness to accept the wholly arbitrary
determination of syntax. Instead, he may have in mind a combination
of limitations due in part to the logical properties of the world and
in part to the pragmatic selection of syntax that is nonetheless, on
some levels, a matter of convention.

Constructions in Early Acquisition
* How do children learn constructions -- noun phrases, verb phrases,
and other phrase types? Do they begin with specific lexical items in
a construction, and use only those? To what extent do they build
from 'verb islands' or 'noun islands' in early constructions? Which
constructions emerge first? What criteria should we use in
establishing productivity? What makes constructions easy versus hard
to acquire? Can children's bases for inferences about the relevant
noun or verb meanings be identified? Are there consistent patterns
across children in the acquisition of constructions? Are there
differences from one verb type to another, or from intransitive to
transitive? Are differences attributable to differences in
frequencies in child-directed speech?
* What crosslinguistic comparisons are available? Which
constructions have been considered in studies of children's early
syntactic forms?

"Digital Mechatronics and Polymer Muscle Actuators for Robotic Systems"
Steven Dubowsky
Field and Space Robotics Laboratory, MIT
Digital mechatronic devices approximate the motion of continuous
mechanisms by using a larger numbers of binary Degrees-of-Freedom.
Digital mechatronic devices have excellent repeatability, are
reliable, robust and are simple to control. Artificial muscle
actuators that are made of elastomers are ideally suited digital
mechatronic devices. These actuators have unique properties such as
very large strain and large forces. They are light and inexpensive.
This makes them appropriate for many diverse applications, from
disposable medical devices to space systems. Using polymer actuators
in binary devices overcome some of their limitations, such as internal
creep, which limit their use in more conventional designs. This
presentation will include recent analytical and experimental studies
of the fundamentals of polymer actuated mechatronic devices.
Applications addressed will include their potential as key elements in
future planetary exploration systems and their current potential
applications in medical robotics.
About the Speaker: Dr. Dubowsky is a Professor of Mechanical
Engineering at the Massachusetts Institute of Technology, Cambridge,
Massachusetts. He is currently a Visiting Professor in the Design
Group of the Stanford Mechanical Engineering Department. Professor
Dubowsky is the director of the MIT Mechanical Engineering Field and
Space Robotics Laboratory ( http://robots.mit.edu/ ). He is the
Principal Investigator of a number of research programs sponsored by
organizations that include DARAP, NASA, The US Navy, The Center For
the Integration of Medicine and Innovative Technology, industry, the
Japanese Space Agency and the British government. The research of
these programs focus on the design and control of robotic
systems. Dr. Dubowsky has published over 200 technical papers and he
is a Fellow of the ASME and of the IEEE.

"Technology-Enhanced Scholarship of Teaching and Learning:
Represent, Share and Build Pedagogical Knowledge Online"
Toru Iiyoshi
Carnegie Foundation
The Knowledge Media Lab at the Carnegie Foundation for the Advancement
of Teaching is working to take advantage of emerging technologies and
new media to transform the knowledge implicit in effective teaching
practice into ideas, theories, and resources that can be shared widely
to advance teaching and student learning at multiple levels. These
efforts are focused in three ways. Firstly, the KML devises new means
of helping faculty document and share their teaching practice and
knowledge online by exploring new genres and models for
multimedia-enhanced teaching portfolios. Secondly, the KML develops
tools and resources that enable faculty and institutions to engage in
this work more easily and effectively. Examples include web-based
knowledge representation and management tools and collaborative online
workspaces. Lastly, the KML fosters the collective knowledge building
of a community of practice and reflection. For instance, innovative
ways of creating and using well-represented pedagogical knowledge in a
variety of contexts and settings, from faculty development to
knowledge community building, are being explored with some of the KML
partner scholars, programs, and institutions.
This presentation will address some of the critical issues around the
work of KML as well as the implications for the ongoing major
educational initiatives taking advantage of technology, such as the
Open CourseWare Project, the Open Knowledge Initiative, and MERLOT.
About the Speaker: Dr. Toru Iiyoshi is Senior Scholar at the Carnegie
Foundation and Director of its Knowledge Media Laboratory
(KML). Iiyoshi is also active with several national and international
initiatives and partners such as the Open Source Portfolio Initiative
where he serves as a Board member as well as an Advisor to the
Council. In this capacity, he provides his vision and leadership in
the development and diffusion of innovative educational
technology. Iiyoshi, a learning scientist and educational
technologist, has been awarded the Outstanding Practice Award in
Instructional Development and the Robert M. Gagne Award for Research
in Instructional Design from the Association for Educational
Communications and Technology. His research focuses on design and
evaluation of cognitive tools and interactive learning environments

"Looking To Understand: The Coupling Between
Speakers' and Listeners' Eye Movements during Discourse"
Daniel Richardson
Psychology, Stanford
Imagine standing in front of a painting, discussing it with a friend.
As you talk, your eyes will scan across the image, moving
approximately three times a second. They will be drawn by
characteristics of the image itself, areas of contrast or detail, as
well as features of the objects or people portrayed. Eye movements are
driven both by properties of the visual world and processes in a
person's mind. Your gaze might also be influenced by what your
friend is saying, what you say in reply, what is thought but not said,
and where you agree and disagree. If this is so, what is the
relationship between your eye movements and those of your friend? How
is that relationship related to the flow of conversation between you?
I will describe an experiment in which participants had their eye
movements recorded while they spoke extemporaneously about a TV show
whose cast members they were viewing. Later, other participants
listened to these speeches while their eyes were tracked. Within this
naturalistic paradigm using spontaneous speech, a number of results
linking eye movements to speech comprehension, speech production and
memory were replicated. More importantly, it was demonstrated that
speaker and listener eye movements were coupled, and that the strength
of this relationship positively correlated with listeners'
comprehension. Just as the mental state of a single person can be
reflected in patterns of eye movements, the commonality of mental
states that is brought about by successful communication is mirrored
in a similarity between speaker and listener's eye movements.

"Advances in Discourse Parsing"
Livia Polanyi
with Martin van den Berg, Chris Culy and Lorenzo Thione
In this talk, we describe the FXPAL Linguistic Discourse Analysis
System (LIDAS), a novel approach to symbolic discourse parsing based
on a limited set of robust syntactic, semantic and lexical
rules. Unlike systems based on Rhetorical Structure Theory which was
designed to account for discourse "coherence" by labeling the
rhetorical relations among text segments (Mann and Thompson, 1984;
Marc 2000) or systems based on Grosz and Sidner's 1984 psychological
Discourse Structures Theory which describes the attentional focus of a
text in terms of the intentions of the text producers, the Unified
Linguistic Model (U-LDM) implemented in LIDAS is designed to account
for discourse anaphora and reference resolution in terms of linguistic
relationships obtaining among discourse segments.
In the presentation, we will discuss how the output of the Xerox
Linguistic Engine (XLE), a Lexical Functional Grammar sentential
parser built at Xerox PARC, is used in the to provide information used
in segmenting sentences into Basic Discourse Units, and in building up
a discourse-tree for each sentence. LIDAS uses information in the
f-structures returned by the XLE together with lexical ontological
information and specific rules of discourse formation to identify
possible attachment points and attachment relations for each Basic
Discourse Unit. To demonstrate the utility of the system in a real
application, we will give a brief demo of the PALSUMM hybrid sentence
extraction summarization system under development at FX Palo Alto
Laboratory. PALSUMM produces highly readable summaries that preserve
the style and tone of the original document as well as assuring that
reference and anaphoric information is properly deployed. PALSUMM
operates on an XML representation of the discourse parse trees output
by LIDAS and uses statistical summarization methods to improve the
focus of and reduce the size of the summaries produced.
