To get more details about the special sessions, authors are encouraged to contact directly the session chairs listed below.
Special session 1: Data Fusion Technology for the Canadian Armed Forces
Session chair:
Mark Edwards,
General Dynamics Canada, Email:
Mark.edwards@gdcanada.com
Objective:
The objective of this session is to explore the application of Data
Fusion to Military needs. As with many other fields of modern endeavor, there are times
when there is too much information to sift through to make proper informed decisions.
This session will address the application of techniques to various operational requirements
to show the real world use of Data Fusion.
Abstract:
There are many ways that Data fusion can support military operations
in areas of Situational Awareness, surveillance, and planning tasks. These requirements
call upon all levels of fusion capability. Accurate and efficient management of information
on the battlefield is vital for successful military operations. The process of collecting,
collating, integrating and interpreting data must be achieved whilst ensuring that no
information is lost. The critical area is to look at the tactical requirements for data fusion,
and to ensure that the technology is supporting the military in performing their tasks in
a more simplified fashion. The purpose of this session is to look at the practical application
of data fusion to Canadian military requirements in a number of areas as outlined in the
topics of interest below. The primary goal is to make the bridge between the theoretical
aspects of data fusion and the practical aspects.
Keywords:
Military, tactical, operational, fusion, joint, Army, Navy Air Force
Special session 2: Image Fusion and Video Fusion Assessment

Stavri
Nikolov, Dept. of Electrical and Electronic Engineering, University of Bristol, UK, Email:
stavri.nikolov@bristol.ac.uk
Objective:
The focus of this session will be on
state-of-the-art methodologies, metrics and tools
used to assess the information content or quality of fused imagery and video, and to
evaluate the performance of image fusion and video fusion systems.
Topic of interest:
The fusion of multimodality
(multi-spectral) image and video sources is emerging as a
vital technique for surveillance purposes, navigation and object tracking applications,
and in medical diagnostics. The main goal of image fusion is to provide a single compact
representation of the input images that is more informative than each of the individual
inputs. There are several potential benefits of multi-sensor image fusion: wider spectral,
spatial and temporal coverage, extended range of operation, decreased uncertainty,
improved reliability and increased robustness of the system performance. The
combination of complementary information from a range of different sensing modalities
can provide enhanced performance for visualisation, detection, tracking, identification
or classification tasks.
The widespread use of image fusion methods has led to a rising demand of pertinent
quality assessment tools in order to compare the results obtained with different
algorithms and systems or to derive an optimal setting of parameters for a specific
fusion algorithm. For man-in-the-loop applications, the performance of the fusion
algorithm can be measured in terms of improvement in operator performance in
different tasks like detection, recognition and classification. This approach requires a
well defined task, for which quantitative measurement can be made, and it usually
involves costly and time consuming field trials. Computational image fusion quality
assessment metrics that relate to human observer performance are therefore of great
value. The assessment can either be done by comparing the fused result with a
reference image that provides the ground-truth, or (since such ground-truth is not
available in most applications) by relating the fused result (or some of its features) to
each of the input images (the so-called non-reference approach). Video fusion
assessment is even more challenging as the spatio-temporal characteristics of the
inputs need to be taken into account. This special session comprises eleven contributed
papers that present some of the latest research in image and video fusion assessment
and its various applications. The focus of the proposed special session will be on
assessment of dynamic fused imagery.

Objective:
To propose an overview of the last main research results and of their applications in this field.
Sensors management must be tackled using several scientific fields like sensors modeling,
optimization, Bayesian inference, detection theory, random sets, communications, sensors
and data fusion or more recently reinforcement learning. Sensors management has many
applications in military and civil domains. The three objectives of this session are to:
Propose an overview of the last main research results and of their applications.

Session chair:
Katia Sycara, Carnegie
Mellon University, USA Email:

Bin
Yu, Quantum Leap Innovations, Inc., USA Email:
byu@quantumleap.us
Objective:
Collaborative sensor systems of the near future are envisioned to consist of hundreds of
unmanned vehicles such as UAVs and UGVs. These networked autonomous and
geographically distributed sensors play strong roles in military and civilian operations,
e.g., battlefield surveillance and disaster rescue. At the same time, sensor systems
offer many exciting research challenges due to their real-world constraints such as
imperfect sensor data, real-time execution, and scarce wireless communication bandwidth.
The purpose of this special session is to bring together the researchers to address the
challenges and opportunities of collaborative sensor systems in mission-critical applications.
The session will solicit papers addressing both theoretical and practical aspects of sensor
systems, as well as their relation to level two fusion (situation awareness) and level three
fusion (threat assessment). In particular, the workshop aims at bridging the gap between
the vast amount of theoretical work on AI, control theory and operation research and the
practical needs of sensor systems research.
The topics of interest include but are not limited to:
Distributed data fusion
Multisensor multimodal data fusion
Coordination (task and resource allocation), planning and scheduling
Sensor data prioritization and dissemination
Reasoning with incomplete, uncertain, deceptive or conflicting information
Reasoning with spatial and temporal sensor data

Abstract:
Sensors like radar, lidar or video systems are more and more employed in vehicles for
advanced driver assistance systems. In this session, methods are discussed how to
combine information from different automotive sensors to achieve a reliable common
perception of the environment. This fusion of information about the vehicle and its
surrounding is one of the basic requirements of future Intelligent Transportation Systems.
Topic of interest:
Today, more and more vehicles are equipped with sensors (like radar, lidar or video
systems) observing the close environment. Maps and communication devices are used
as an additional source of information. The aim is to use the knowledge about the
surrounding to enable the driver to use his vehicle more comfortably and safely even in
difficult situations. Proposals for Intelligent Transportation Systems aim at having an
“intelligent electronic co-driver” assisting and warning the driver or even intervening
when necessary.
To achieve this, a profound knowledge of the vehicle surrounding is required.
In a first approach, information of a single sensor has often been directly linked to vehicle
applications. As complexity and demands for reliability rise, often more than a single
sensor is employed. Then the question arises how to fuse these different sources of
information to a common understanding of the environment in the best way. Some
solutions are already available, but further progress is needed to fulfil all requirements.
In the proposed session, different concepts and methods for combining information
from automotive sensors shall be discussed. A general objective is to derive a
representation of road and objects in the vehicle’s surrounding based on a set of
sensor measurements. Different methods to achieve this common goal will be explained
and discussed in the session.
The processing of automotive sensor data can be structured into sensor data
refinement, object refinement and situation refinement. Different aspects of these
processing steps shall be addressed in this session.
An additional point of interest it the development process of data fusion systems for ITS
purposes. Here, one question is how to validate the result of a fusion system, e.g., as
compared to a single sensor, but also with respect to expected detection properties and
false alarm rates.
Using data fusion systems in automotive application implies some particular
requirements. On one hand side, information complexity and density varies a lot
depending on the type of considered traffic scenario and application. On the other
hand, demands on perception reliability and improved real-time capability constantly
increase due to the development of new active safety functions.
By taking these requirements of vehicular sensor data fusion systems into special
account, this session shall contribute to an exchange of recent research developments
within Intelligent Transport Systems and the broader scope of the information fusion
community.

Special session 6: Context Information in Data Fusion
Session chairs:

Abstract:
Contextualized Information Fusion groups a large variety of disciplines: distributed
intelligence, data and information communication, software design, computer vision,
speech recognition, robotics, information fusion, etc. The broad concept of “Ambient
Intelligence” (AmI) should be here understood as one where mobile services,
whichever they are, are provided to the final user in a transparent, ubiquitous,
continuous and personalized way. In a broad sense, AmI paradigm deals with
pervasive systems assisting the users by autonomously interpreting their intentions
and trigger automatic reactions. It is focused on intelligent environments,
"walls with eyes and ears" to "sense" the users and aid them in their daily tasks.
The basic idea for developing AmI application is of a distributed layered architecture
enabling ubiquitous communication and an advanced human–machine communication
protocol. A wide range of application domains can benefit from AmI research as appear
in the European Commission document entitled Scenarios for Ambient Intelligence in
2010 written by the IST Programme Advisory Group (ISTAG) for the Fifth European
Framework Programme (1998–2002). An updated version of the continuously evolving
vision of the report appeared in 2003 under the title Ambient Intelligence: from vision to
reality, putting forward ideas for the currently open Sixth Framework Programme
(2002–2006). A system based on AmI criteria requires a bundle of technologies to
implement modularity, low-power devices, distributed and high band-width heterogeneous
networks of sensors and actuators. Modular units of intelligence (agents), will create a
distributed layer of intelligence, from the sensing to the understanding of information.
Machine understanding includes research in the fields of computer vision, machine
learning, situation assessment, and any other techniques applied by the community
working on information fusion.
From the conceptual point of view, this session intends to contribute in works to the DATA
FUSION approach associated to ambient intelligence, from the “user/network-centric”
approach of cooperation and resource-sharing on which distributed systems are based
(“shared situational awareness”, users networks and ad-hoc networks). In particular,
effective exploitation of contextual information represented as knowledge-bases (KB),
e.g. environmental maps and characteristics of the targets of interest is a powerful tool
to gain adaptability and improved performance in the fusion process and inferences
about interesting events. An effective use of the KB can be exploited at various levels of
the fusion architecture algorithms so as to significantly reduce the number of false
alarms, missed detections, and false tracks and improve true target track life
(system robustness).
Objective:
The focus of this special session is on the Data Fusion techniques within the AmI
applications. This is a fundamental step to create a first level of user-awareness in
the environments. The main topics would include:
distributed architectures for Data Fusion using Context Information;
sensors and communication required for the Data Fusion infrastructure of an AmI applications
advanced technology in areas of wifi networks, computer vision related with data fusion problems
artificial Intelligence solutions to distributed reasoning and sensor cooperation
different application domains including health, practical skills training, public spaces
management, etc.;
Special session 7: High-level Information Fusion on Cognitive Arena
Session chair:
Gee Wah, NG, Advance
analysis and Fusion Laboratory, DSO National Laboratories, Email:
ngeewah@csail.mit.edu
Objective:
To address the issue on high-level information fusion such as situation
assessment and impact assessment, in the cognitive domain.
There are increasing interests in research on high-level information fusion, particularly at the situation
assessment and impact assessment. Under situation assessment, the goals include deriving higher-order
relations and identifying meaningful events and activities. Impact assessment includes estimating the level
of threat or danger, predicting possible outcomes of particular decisions, determining the vulnerabilities of
one’s own assets and determining possible courses of actions. It is inevitable that the high-level
information fusion will cover the cognitive arena, such as cognitive intelligence, cognitive architectures,
cognitive decision aids, sensemaking and bio-inspired intelligent fusion process for situation awareness
and impact assessment.
Topics appropriate for this special session include (but are not necessarily restricted to):
Cognitive-based situation and threat assessment
High level Information fusion based on cognitive framework
Multi-sensor, multi-source fusion system architectures for situation awareness
Computational or Cognitive intelligence techniques for high-level information fusion
Decision fusion
Conflict management in high-level fusion
Knowledge based and probabilistic reasoning in high-level fusion
Bio-inspired Intelligent Fusion System
Ontology-based approaches for high-level information fusion
Advanced analysis and intent inference

Abstract:
Situation Management (SM) is a fairly new term applied to the management of complex dynamic systems. People, whose interest is in situations happening in dynamic systems, are more familiar with the terms of Situation Awareness, Situation Calculus, Situation Semantics, and Situational Control. Situation Management as a management concept, technology, and a reference to the domain of applications, is taking roots from all of the above-mentioned disciplines, but it also aims to build a comprehensive and more general framework of concepts and enabling technologies for understanding and affecting situations that are happening or might happen with certain systems in a specific domain of interest. The objective of this session is to provide research and applications forum for advancing the SM technology, especially the issues related to high level (cognitive). The session continues the discussions started at the SM sessions at FFUSION 2006 in Florence, Italy.
Our interest will be mostly on cognitive aspects of situation management, i.e. on aspects related to the meaning of situations, the intelligent methods of reasoning about the situations, and action planning. In order to exhibit such intelligent capabilities, the systems should possess fairly elaborate conceptual knowledge about the domain, i.e. domain ontology.
Technical Scope:
Situation Modeling
Situation Ontologies and Semantics
Situation Monitoring and Awareness
Reasoning about Situations
Learning and Situation Discovery
Cognitive Models of Information Fusion
Image and Sensor Fusion
Knowledge Fusion

Course level: Intermediate
OUTLINE
Lesson 1: Introduction - Importance of Sensor Fusion
Lesson 2: Sensors and Architectures - JDL Levels 1 - 5, Decision making
Lesson 3: Reducing the error /uncertainty, compensating for unknown
Lesson 4: Fusion System Evaluation - Fusion Gain, ROC Curve, Uncertainty Analysis
The tutorial is intended to cover the general topics concerning data and information fusion use with emphasis on pragmatic fusion techniques. By highlighting the advantages and disadvantages of fusion, one can assess the gain of using multiple sources of information. Many users are excited about the prospects of the concept called "fusion"; however, if applied inappropriately, could result in detrimental effects. To mitigate the embellished opportunities of fusion, it is important to correctly evaluate fusion systems and appropriately quantify the "fusion gain".
By introducing fusionists to metrics and evaluation techniques, one can determine if combining multiple sources of information is justifiable. The first session introduces the importance of fusion, as in using different sensors to capture observable quantities about the environment. The second session details the larger organization of fusion systems as machines that process large quantities of data and reduce the dimensionality for a user to reason and make decisions over. The third topic highlights the fact that any information uncertainty must be reduced for the user. In the third session, mathematical techniques to reduce uncertainty are explained and developed within complex system design. If the user is better able to make decisions with appropriate mathematical models for information fusion, data collection, and timeliness of results; the fusion system is doing its job.
The final session details the process by which a fusionist can determine a "fusion gain" for user decision making and verifiable situational awareness. A fusion evaluation process will be explained which includes
(1) metrics for testing,
(2) design of experiments analysis over operating variables, and
(3) examples of successful fusion evaluation techniques.
After attending the tutorial, the student would better appreciate the complexity surrounding defending a realistic efficacy in fusion system performance, knowledge of where to get information in developing a fusion test plan, and practical examples and performance evaluation studies that include end users and field tests of such systems in complex environments.

Abstract:
This tutorial is intended to provide a detailed understanding of both
the cutting-edge and the most commonly used computational approaches to situation
assessment (a.k.a. level 2 fusion) and the associated generation of appropriate
response recommendations for decision making under uncertainty.
A diverse range of level 2 fusion techniques, including Bayesian belief
networks, fuzzy logic, and the theory of belief function, will be covered in the tutorial.
These techniques are suitable for modeling uncertain knowledge under different
situations, and their suitability will be discussed in each case. A number of temporal
modeling techniques, such as dynamic belief networks and hidden Markov models will
also be presented. The tutorial will discuss interactions between level 1 and level 2
fusion processes. Special emphasis will be given to a discussion on particle filtering
techniques as unifying methods for both filtering under level 1 fusion and inferencing
in dynamic Bayesian networks for Level 2 fusion. Finally, distributed level 2 fusion
techniques, as appropriate within network centric warfare environments, will be
discussed.
For the response recommendations part of the tutorial, traditional
expected utility theory, rule-based expert systems, and influence diagram based
decision-making processes will be described. Then a symbolic argumentation technique
using first-order and non-classical modal logics will be presented. Various techniques
for aggregating arguments including probability, possibility, and Dempster-Shafer
theories will be covered. The argumentation technique and probabilistic aggregation
are the major focus of the speaker’s recent book on symbolic decision-making and a
forthcoming book on the foundations of decision-making agents.
As for software tools, an in-house 5th generation application
development platform (Prolog and Lisp) and argumentation building engine (Reason),
and an in-house belief network engine (BNet@Builder, with its temporal extension) will
be used for illustrating response recommendations and situation assessment
respectively. The commercial-off-the-shelf tools Matlab and Hugin will be used for
illustrating Kalman/particle filtering for level 1 fusion, fuzzy inferencing, and influence
diagrams for decision-making. Military examples and prototype demos involving tasks
of determining relationships among entities and events, target classification, and
target identification will be provided throughout the tutorial.
Prerequisite:
Background in the basics of probability and statistics, mathematics,
and a basic understanding of artificial intelligence.

Abstract:
The combination of information is a hot topic of research specially in the development
of complex systems involving imprecise, uncertain and potentially highly conflicting
information/data with usually (but not necessarily) human interaction at some higher
fusion level for efficient decision-making. Modern multisensor systems for tracking,
classification, diagnosis, situation assessment, etc need solid theoretical tools to
combine efficiently information in order to reduce as best as possible ignorances and
contradictions in a coherent way to help to take proper decision. This task is very difficult
and many theories (probability theory, possibility theory, Dempster-Shafer theory
(DST), etc) have been proposed to deal with different kinds of uncertainties
(randomness, fuzziness, epistemic nature, etc). After a brief reminder of classical
combination rules based on belief functions used up to now in most of (non Bayesian)
multisensor/expert systems, a detailed presentation of foundations and advances
obtained in the development of Dezert-Smarandache theory (DSmT) for the
combination of uncertain, imprecise and potentially highly contradicting sources of
information will be given. DSmT appears as a natural extension of DST because DSmT
takes into consideration any kind of model (free, hybrid DSm models and also the
classical Shafer's model) according to the integrity constraints of the fusion problem.
DSmT proposes a new mathematical framework and rules for information fusion that
potentially allows some intersections of elements of the frame (i.e. some degree of
consensus between elements). Fusion rules developed in DSmT framework overcome
limitations of Dempster's rule and its alternatives as it will be showed in very simple
examples. DSmT appears well adapted to static or dynamic fusion applications
represented in terms of belief functions based on the same unified general
mathematical formalism. The mathematical level of this tutorial and didactic examples
will be kept as simple as possible to show the advantages of this new approach over
previous ones. Aside basis of DSmT, we will present the recent Proportional Conflict
Redistribution (PCR) rules and show their performances on several examples and will
present also a new general arithmetic for the fusion of qualitative beliefs. An
introduction to new quantitative belief conditioning rules will be also presented. A direct
extension of the quantitative/numerical information fusion and conditioning rules to
their quantitative counterparts in order to deal with qualitative information drawn from
human sources and expressed in natural language will complete this tutorial.

The attendees of this tutorial will received a printed copy of the
presentation and as bonus material a printed copy of the last book published by the
authors entitled « Advances and Applications of DSmT for Information Fusion »,

in 1997, and continued postdoctoral studies at various American Universities
(New Mexico State University in Las Cruces, Los Alamos National Laboratory) after
emigration. In 1988 he escaped from his country, pasted two years in a political refugee
camp in Turkey, and in 1990 emigrated to USA. In 1996 he became an American citizen.
Dr. Smarandache worked as a professor of mathematics for many years in Romania,
Morocco, and United States, and between 1990-1995 as a software engineer for
Honeywell, Inc., in Phoenix, Arizona. In present, he teaches mathematics at the
University of New Mexico, Gallup Campus. Very prolific, he is the author, co-author, and
editor of 75 books, over 100 scientific notes and articles, and contributed to about 50
scientific and 100 literary journals from around the world (in mathematics, informatics,
physics, philosophy, rebus, literature, and arts). He wrote in Romanian, French, and
English. Some of his work was translated into Spanish, German, Portuguese, Italian,
Dutch, Arabic, Esperanto, Swedish, Farsi, Arabic, Chinese. He was so attracted by
contradictions that, in 1980s, he set up the "Paradoxism" avant-garde movement in
literature, philosophy, art, even science, which made many advocates in the world, and
it's based on excessive use of antitheses, antinomies, paradoxes in creation - making
an interesting connection between mathematics, engineering, philosophy, and literature
and led him to coining the neutrosophic logic, a logic generalizing the intuitionistic fuzzy
logic that is able to deal with paradoxes. In mathematics there are several entries
named Smarandache Functions, Sequences, Constants, and especially Paradoxes in
international journals and encyclopedias. He organized the 'First International
Conference on Neutrosophics' at the University of New Mexico, 1-3 December 2001.
Small contributions he had in physics and psychology too. Much of his work is held in
"The Florentin Smarandache Papers" Special Collections at the Arizona State University,
Tempe, and Texas State University, Austin (USA), also in the National Archives
(Rm. Vâlcea) and Romanian Literary Museum (Bucharest), and in the Musée de
Bergerac (France). In 2003, he organized with Dr. Jean Dezert, the first special session
devoted to plausible and paradoxical reasoning for information fusion at the Fusion
2003 in Cairns, Australia and has participated to several international workshop and
seminar on Information Fusion since 2003. He published two books devoted to
DSmT-based Information Fusion in 2004 and 2006 respectively. The complete list of

Intended audience:
This tutorial is directed towards
both researchers and practitioners
in various areas of information fusion.
Prerequisites:
Basic knowledge of logic. Familiarity with declararive programming
is desirable but not required./P>
Description:
In this tutorial the participants will learn:
how “situation” can be formalized
what an ontology is
how to represent ontologies in the OWL language using an OWL tool
how to check consistency of an ontology
how to build rules on top of an ontology
how to use a general reasoning tool to monitor or query situations
what kind of situation-related reasoning can be performed and how
Higher-level fusion involves estimation of abstract entities - sometimes called “situations” - that can be represented as relations among objects, both physical and conceptual. Unlike features of physical objects, features of relations are not directly measured by sensors. Instead, the existence of a relation is derived from a domain theory relevant to a specific scenario.
This tutorial will cover both theoretical and practical aspects of situation awareness and high-level information fusion. First, a motivational example will be given to demonstrate the importance of relations and to introduce the concept of situation. This will be followed by a presentation of some methodological techniques and some technologies that are needed for establishing an ontological approach to higher level information processing. The notion of ontology will be introduced in theoretical, computational and practical terms. Examples of specific ontologies will be discussed using both a graphical representation and an evolving standard language used for communicating ontologies and annotations as well as for processing and fusion of semantic annotations (OWL – Web Ontology Language). An overview of OWL constructs will be provided using Protégé, the most popular tool for editing ontologies, and some graphical plugins. Other tools will also be demonstrated in the context of a methodology for ontology engineering. Situation awareness and high-level information fusion will be discussed using an illustrative example.

Abstract:
Possibility theory and the body of aggregation operations from fuzzy
set theory provide some tools to address the problem of merging information coming
from several sources. Possibility theory is a representation framework that can model
various kinds of information items: numbers, intervals, consonant random sets, special
kind of probability families, as well as linguistic information, and uncertain formulae in
logical settings. The possibilistic approach to fusion is general enough to encompass
logical modes of combination (conjunctive and disjunctive) as well as fusion modes
used in statistics. The choice of a fusion mode depends on assumptions on whether
all sources are reliable or not, and can be based on conflict analysis. A possibilistic
logic counterpart of the combination modes applicable to possibility distributions has
been developed. The approach applies to sensor fusion, aggregation of expert opinions
as well as the merging of databases especially in case of poor, qualitative information.
This general framework allows us to import inconsistency handling methods, inherited
from logic, into numerical fusion problems. Quantified, prioritized and weighted fusion
rules are described, as well as fusion under a priori knowledge. It has been shown that
the possibilistic logic setting is compatible with the Bayesian approach to fusion, the
main difference being the presupposed existence, or not, of prior knowledge. Relations
and comparisons with combination rules in other frameworks such as Shafer theory of
evidence will be discussed. Finally, fusion will be also presented in bipolar possibility
theory, a framework that distinguishes between positive and negative information.
The approach applies to sensor fusion, aggregation of expert opinions as well as the
merging of databases especially in case of poor, qualitative information. The approach
proposed and the results presented have been obtained in collaboration with Didier
Dubois.

Abstract:
For 170 years, people have been arguing about whether probability is
objective or subjective. From the game-theoretic point of view that emerges
from my 2001 book with Vladimir Vovk (Probability and Finance: It’s Only a
Game, Wiley), the question is instead whether a particular decision problem
is embedded in a repetitive structure. The method of defensive forecasting,
developed by Vovk in more recent work, gives probabilities for decision
making in problems that are sufficiently repetitive, without any a priori
assumption about trials being identical. But when the focus is on the
particular case rather than on long-run average performance, and when
there is even contention about what long-run sequence the particular
case should be compared with, we need instead methods of weighing
evidence.
Biography:
Glenn Shafer spent his childhood on a farm near Caney, Kansas. He earned
two degrees from Princeton University: an A.B. in mathematics in 1968 and
a Ph.D. in mathematical statistics in 1973. After teaching in the Department
of Statistics at Princeton, he returned to Kansas in 1976 to teach in the
Department of Mathematics at the University of Kansas. In 1984, he moved
from Mathematics to Business at Kansas. Since 1992, he has taught in the
Rutgers Business School–Newark and New Brunswick.
In 1976 Glenn published
A Mathematical Theory of Evidence, which formulated
the Dempster-Shafer theory of belief functions, now widely used for handling
uncertainty in expert systems. In 1996, he published a second major book,
The Art of Causal Conjecture
, which is concerned both with expert systems
based on causal models and with the empirical investigation of causality.
His most important work is
Probability and Finance: It's Only a Game!
This
book, co-authored by
Volodya Vovk
and published in 2001, shows how game
theory can replace measure theory as a foundation for mathematical
probability. The new foundation is elegant and powerful, and Glenn believes
that it will eventually reshape the use of probability in many different fields.
It has immediate applications in finance, where it points the way to pricing
options and evaluating the performance of investments without assuming
that markets behave randomly. It strengthens Glenn's earlier analysis of
causality and provides a new way of understanding the distinction between
objective or causal probability on the one hand and subjective or personal
probability on the other.
Glenn has published in journals in statistics, philosophy, history, psychology,
computer science, economics, engineering, accounting, and law. He has won
teaching awards in both mathematics and business. He was a Guggenheim
fellow in 1983-84, a fellow at the Center for Advanced Study in the Behavioral
Sciences in 1988-89, and a Fulbright fellow at the Free University of Berlin in
Spring 2001. He is a fellow of both the Institute of Mathematical Statistics
and the American Association for Artificial Intelligence.

Keywords:
Distributed sensor systems, data fusion,
task allocation, path planning.
Target audience:
This tutorial is intended for any
delegates who have some basic
knowledge of AI and algorithms. Familiarity with basic concepts of sensor systems
is desirable but not essential.
The topic of sensor systems is of general interest for Fusion 2007
attendees. A similar tutorial at Fusion 2006 was deemed to be highly successful,
attracting one of the largest number of attendees in any tutorial at Fusion 2006.
Abstract:
Robotic sensor systems of the near future are envisioned to consist
of hundreds of unmanned vehicles such as UAVs and UGVs. These networked
autonomous and geographically distributed sensors play strong roles in military and
civilian operations, e.g., battlefield surveillance and disaster rescue. At the same time,
sensor systems offer many exciting research challenges due to their real-world
constraints such as imperfect sensor data, real-time execution, and scarce
wireless communication bandwidth. Many algorithms have been developed in
the context of sensor systems, however, most of them are centralized and not
scalable due to their optimistic assumption of unlimited communication bandwidth.
In this tutorial we will survey the state-of-the-art of distributed algorithms
for collaborative sensor systems, where sensors need to be coordinated in an effective
way. We will summarize major advances of distributed coordination theories and
algorithms in the areas of AI and multiagent systems. Specifically, we will focus on the
design and analysis of distributed coordination algorithms for data fusion, task
allocation, and cooperative path planning in a large-scale autonomous sensor system,
where large numbers of autonomous mobile sensors may enter and leave the system
dynamically. We will conclude by discussing some open research issues in distributed
coordination algorithms and their relation to other fields, such as control theory and
operation research (OR).
