"Negative Selection Algorithm for Anomaly Detection"
Dipankar Dasgupta
University of Memphis, Tennessee
Visiting Scholar, NASA Ames Research Center
The biological immune system is a complex adaptive system which
efficiently employs several mechanisms for defense against foreign
pathogens. Self-nonself (or danger) discrimination is one of the
important tasks the immune system performs during the process of
pathogenic recognition and responses. This discrimination is achieved
in part by T-cells, which have receptors on their surface that can
detect foreign proteins (antigens). During the generation of T cells,
receptors are made by a pseudo-random genetic rearrangement process.
Then they undergo a censoring process, called negative selection, in
the thymus where T cells that react against self-proteins are
destroyed; so only those that do not bind to self-proteins are allowed
to leave the thymus. These matured T cells then circulate throughout
the body and work as distributed novel pattern recognizer. The talk
will present an immunity-based negative selection algorithm (and
discuss negative detector generation techniques), and its application
in anomaly and fault detection.

"Ubiquitous Web Browsing"
Daniel F. Zucker
ACCESS Co. Ltd.
Computing is now in the midst of yet another great paradigm. First
mainframes gave way to mini-computers, then mini-computers to PCs, and
today handheld computers are drastically outnumbering PCs. For 2003,
compared with 164 Million PCs, approximately 510 Million mobile
handsets were sold (Gartner). Virtually everyone now carries a
cellphone with them everywhere; and a cellphone is today just a
specialized type of mobile computer. With increasing computing power,
increasing storage capacity, and plummeting costs, soon everyone will
be armed with an ubiquitous general purpose mobile computer.
ACCESS Co. Ltd., is the world's leading supplier of web browsers for
mobile, wireless, and embedded devices. ACCESS is based in Tokyo, a
center of leading-edge mobile wireless technology. Our browser has
been ported to many operating systems and hardware devices. The web
browser is often the gateway application to mobile information, media,
and services. This talk presents an overview of mobile applications
and trends in mobile terminals and PDA devices.
I survey smartphones OSes, some popular mobile CPU architectures, and
present several demonstrations of the latest mobile multi-media
technology. The system-level components that enable comprehensive
mobile computing of today will also drive the ubiquitous web browsing
of tomorrow.
Additional information: This talk was originally given as a Keynote
address at Cool Chips in Japan.

"Squealing Tires:
Researching where the rubber meets the road in corporate environments"
Christian Rohrer
Yahoo
A good education comes from a reputable school, great program, helpful
advisors, and years of hard work. However, the academic experience is
really only the foundation for being an effective research
practitioner in a corporate setting.
In this discussion, I will cover topics such as:
* How research is used in corporate settings: its role and function
* Skills that will serve you well:
- Rapport building
- Communication
- Selling and marketing
- Going beyond results and into solutions
- Focus on why and how, not just what and how much
* Corporate politics: playing the game
* Going beyond research
- Using your personality
- Creating an real impact on products
- Moving up and moving on
About the Speaker: Christian Rohrer received his Ph.D in Symbolic
Systems in Education (Cognitive Science) from Stanford University in
2001. His dissertation dealt with the issue of how joint exploratory
learning of a user interface takes place in a household where multiple
people participate in the interaction of a TV-based Internet
appliance. He is currently the Director of User Experience Research
at Yahoo!, where he previously held positions as Usability Engineer
and Senior Manager of User Experience Research over the past 5 years.
Prior to Yahoo!, he conducted ethnographic research for Network
Computer Inc. (now Liberate), consulted as a technical instructor, and
UNIX technician, and served as a technical support engineer for SCO
Group. He also holds a Bachelor's degree in Computer and Information
Sciences from the University of California, Santa Cruz.

"Probabilistic Activity Monitoring using
Quantitative Temporal Relationships"
Bart Peintner
University of Michigan (visitor at SRI)
Activity monitoring is often a necessary ability for systems that
assist people with various tasks. In general, activity monitoring can
be performed by using a stream of sensor data and a model of a persons
behavior and environment to infer which actions have been performed
and the current state of the environment. When the available sensor
data is limited, the monitoring task must rely heavily on the temporal
aspects of the behavior model. However, with current modeling
formalisms, such as Dynamic Bayesian Networks, it is difficult to
represent complex temporal relationships. I will show how to extend
these formalisms to represent and efficiently reason about complex,
quantitative temporal relationships and describe a parameterization
strategy that allows easy specification of the model.
About the Speaker: Bart Peintner is currently in the midst of a two
month visit to SRI. He is a Ph.D. candidate in computer science at
the University of Michigan, studying in the AI laboratory under the
direction of Martha Pollack. His main interest is in automated
temporal reasoning, both probabilistic and deterministic. He received
an M.S. in computer science at the University of Michigan, and a
B.S. in Electrical Engineering at Kansas State University.

"You Say Tomato, I Say Tomahto:
Examining Social Identification Effects in
Mediated Communication with Offshore Call Center Agents"
Sheba Najmi
M.S. Candidate, Symbolic Systems Program
Through most of human history, interaction with others has been
face-to- face. Today, technology is promoting rapid globalization.
While allowing interactions with others from across the world,
globalization has also resulted in the outsourcing of jobs, which is a
hotly-debated topic. Call centers are at the heart of this debate.
John Kerry is pushing for a bill for location disclosure by call
center agents. Dell is under fire for the thick accents of its call
center agents in India. What does all this uproar mean? In this talk,
I shall explore how the location of the call center agent and the
accent of the agent influence people's perceptions of the agent's
competence, engagement, and amiability, in the context of an
experimental study. This experiment is the second in a series of
studies.

"Revisiting Population Codes"
Alex Pouget
Brain and Cognitive Sciences, University of Rochester
http://www.bcs.rochester.edu/people/alex
Many studies have attempted to relate changes in behavior (e.g. as a
result of perceptual learning or increased attention) to changes in
neural codes. One general principle has emerged from these studies:
the steeper (or the narrower) the tuning curve, the better the
performance, or equivalently, the higher the information. This
principle, however, is based on the assumption that increasing the
slope of the tuning curves does not affect the noise distribution.
We will show that in networks of spiking neurons, this assumption
does not necessarily hold. In many networks, an increase in the slope
of the tuning curve leads to changes in the noise distribution, such
that the overall information decreases. We will illustrate this
problem in the context of orientation selectivity. We will show that
sharpening tuning curves through lateral connections results in very
large information loss and leads to complex codes. We will discuss
the implications of these findings for the neural basis of perceptual
learning and attention.
About the Speaker: Alex Pouget is a Professor in the Department of
Brain and Cognitive Sciences in the University of Rochester. His
focus is on general principles of neural computation, with a special
emphasis on population codes. His work bridges the gaps between
the coding of sensory stimuli (e.g. location of objects), observer
co-ordinates (e.g. head and eye orientation) and motor representations
(e.g. for reaching or navigation). He links experimental observations
on patients with theories of cortical computation based on advanced
theories of Bayesian statistical inference.

"Noise and Reliability in Genetic Regulatory Circuits"
Harley McAdams
Stanford University
A complex control system constructed from biochemically-based logic
circuitry governs cell's responses to external signals and management
of their internal operations. In many of the critical reactions of
this circuitry, particularly the genetic mechanisms of gene
expression, the concentration of participating molecules is very low.
This leads to stochastic variation in reaction rates in the circuits.
The result is uncertainty in timing of decisions and even, in some
cases, to uncertainty in phenotype outcomes. We will discuss the
physical origins of this noise, the consequences of the noise in human
and bacterial genetics, and some of the mechanisms used to achieve
high reliability necessary for creation of complex organisms in spite
of the noise.

"Disambiguating Japanese Compound verbs"
Kiyoko Uchiyama
The treatment of multiword expressions (MWEs) has attracted much
interest as an important issue (Sag 2002). Japanese has diverse types
of MWEs and there are difficulties in processing them (Baldwin
2002). In those studies, MWEs are defined as a "word with spaces" in
English and "idiosyncratic interpretations that cross word boundaries"
in Japanese. In English, verb particles have been studied as one type
of MWEs (Villavicencio 2002). We predict that verb particles in
English and compound verbs in Japanese have commonalities in terms of
ambiguity and semantic constraints. For example, the English particle
"up" has both an aspectual ("finish up writing" cf. "kaki-owaru") and
a spatial meaning ("go up the stairs" cf. "kake-agaru"), which is
equivalent to the second verb in Japanese compound verbs. We
investigate Japanese compound verbs (JCVs) and extract semantic
constraints for the purpose of applying them to machine translation.
We propose a disambiguation method to identify the meaning of JCVs
using three sources of information: a statistical approach by learning
basic senses of arbitrary JCVs, a rule based approach which utilize
semantic features and syntactic information.
In the statistical approach, we try to identify the meaning of JCVs
efficiently. There are some JCVs whose meaning is defined only by the
combination of each constituent without context. In those cases, it is
desirable to process JCVs by using collocation information between V1
and V2 automatically. We use a support vector machine as a supervised
learning algorithm to learn basic senses of arbitrary JCVs using the
collocation patterns of V1 and V2 extracted from a corpus.
In the rule based approach, we identify the meaning of ambiguous JCVs
by assigning them to disambiguation rules after machine learning. We
use two steps to construct a disambiguation rules. The first step is
to identify the meaning of V1 using rules which an MT system or other
lexical database should already have. The second step is to classify
JCVs into semantic clusters and extract commonalities of semantic
features on V1 (semantic information) and verb complements (syntactic
information). We build rules using this derived semantic and syntactic
information. The proposed method based on machine learning and
disambiguation rules has the advantage of being able to analyze new
compound verbs not in the dictionary.

"Enhancing User Experiences in Ubiquitous Computing"
Jennifer Mankoff
Group for Interface Research, UC Berkeley CS
Ubiquitous computing in it's idealized form brings to mind a vision of
calm, yet reactive environments filled with appropriate and timely
support for user needs. In practice, this vision is hard to achieve
due to many complications including the difficulty of accurately
sensing and interpreting user needs, and of building and testing
applications. I will present our work in supporting rapid, iterative
design of peripheral displays. These displays help to support
awareness of information when the user is involved in other
activities. They are a crucial piece of Weiser's original vision of
calm environments, and thus an important part of creating a positive
user experience of Ubiquitous Computing. However, they are difficult
to build and evaluate. Our work involves a combination of tool support
and explorations of different evaluation techniques.
About the Speaker: Dr. Jennifer Mankoff is an Assistant Professor of
Electrical Engineering and Computer Science (EECS) at the University
of California at Berkeley. She earned her B.A. at Oberlin College and
her Ph.D. in Computer Science at the Georgia Institute of
Technology. Her research focuses on tools and techniques for rapid,
iterative prototyping of ubiquitous computing applications and
accessible technology. Her research interests also include mediation
of ambiguous, recognition-based interfaces. Application areas of her
work include assistive technology for people with special needs and
health and safety.

"Automating CapCom:
The Mobile Agents Integrated Field Test at the Mars Desert Research Station"
William J. Clancey
Human-Centered Computing Computational Sciences Division
NASA Ames Research Center
More than twenty scientists and engineers from three NASA centers and
two universities refined and tested the Mobile Agents system in a
series of incremental scenarios at the Mars Desert Research Station in
April 2003. Runtime agent software, implemented in Brahms, processed
GPS, health data, and voice commands-monitoring, controlling and
logging science data throughout simulated Extra Vehicular Activity
(moon walk, space walk, etc.) with two geologists. Brahms is a
modeling and simulation environment that includes a multi-agent
programming language for modeling and simulating how people work and
collaborate in a work system. (For more information, see
BrahmsWorkingPaper.pdf ) Predefined Extra Vehicular Activity (EVA)
plans, modified on the fly, enabled the Mobile Agents system to
provide navigation and timing advice. Communications were maintained
over five wireless nodes distributed over hills and canyons for 5 Km.
Science data, including photographs and status, were transmitted
automatically to a remote support team.
This talk presents examples from Apollo lunar traverses and Mars
analog missions that suggest methods for augmenting human capability
to make operations safer and more efficient, while reducing flight
controller supervision. Many photographs and videos show how the
distributed system is developed in the context of use, establishing a
baseline for field science requirements relative to Mars. Issues in
extending the system to facilitate cooperation of multiple robots and
astronaut teams are also considered.
About the speaker: Dr. William J. Clancey is Chief Scientist for
Human-Centered Computing at NASA Ames Research Center, Computational
Sciences Division, where he manages the Work Systems Design &
Evaluation Group. He is on leave from the Institute for Human and
Machine Cognition, Pensacola.
Clancey's research includes work practice modeling, distributed
multiagent systems, and the ethnography of field science. Projects in
his group include participation in MER mission operations, simulation
of a day-in-the-life of the ISS, knowledge management for future
launch vehicles, and developing flight systems that make automation
more transparent.
Clancey has degrees in Mathematical Sciences (BA, Rice University,
1974) and Computer Science (PhD, Stanford University, 1979). At the
Knowledge Systems Laboratory of Stanford University (1974-1987),
Clancey developed some of the earliest artificial intelligence
programs for explanation, the critiquing method of consultation,
tutorial discourse, and student modeling. Prior to joining NASA, he
was a founding member of the Institute for Research on Learning
(1987-1997) where he co-developed the methods of business anthropology

"Security and risk management in the online service environment:
the case of Microsoft Passport"
Cem Paya
Microsoft
This talk will explore the challenges associated with managing
security for the Microsoft Passport identity management system.
Identity management in itself is a well-understood problem but the
unique characteristics of operating a service for 200M end-users adds
new complications. As starting point we examine where identity
management fits in the bigger picture of online interactions, explain
the reasons why Passport exists and offer predictions about how
authentication on the Internet is likely to evolve. Strict constraints
around reliability, interoperability with installed software base and
ease-of-use apply to security measures which can be deployed for a
service of this nature. We observe that the risk model for a service
is inherently different than that of a shrink-wrapped application,
which has implications for operations, incident response and
vulnerability disclosure. That unique character drives the overall
strategy and determines how different pieces such as cryptography,
systems security, human factors, operations, policy and economics
interact. These implications will be examined in the context of
specific problems Passport faces, including the efficient use of
cryptography on large scale and battling spam for Hotmail.
