INVITED KEYNOTE SPEECH – 1

Monday, July 6, 9:00-10:00 / ROOM 1

Sukarno J. Mertoguno

Office of Naval Research, USA

Title: Symbiotic Statistical and Formal Reasoning

Abstract:

The speech will provide a broad overview of research sponsored by ONR related to cyber security and

complex software. Emphasis will be given to new concepts for symbiotic integration of formal rule-

based and statistical-based machine learning and reasoning.

Real-time autonomy is a key element for system which closes the loop between observation,

interpretation, planning, and action, commonly found in UxV, robotics, smart vehicle technologies,

automated industrial machineries, and ONR’s autonomic computing. Real-time autonomic cyber

system requires timely and accurate decision making and adaptive planning. Autonomic decision

making understands its own state and the perceived state of its environment. It is capable of

anticipating changes and future states and projecting the effects of actions into future states.

Understanding of current state and the knowledge/model of the world are needed for extrapolating

actions and deriving action plans. Humans have gut-feeling (fast and shallow reasoning, and reflexive

actions) and deliberative thinking (slower and deeper reasoning, and deliberate actions). Models of

how these two systems of intelligence interact with each other have been proposed for human decision-

making, e.g., the two-systems model by Daniel Kahneman. These interacting models could inspire

approaches for machine reasoning in autonomic cyber and cyber-physical systems. Methods are being

developed for merging statistical inference and formal reasoning by merging their knowledge a unified

representation. An alternative method ONR is promoting, took the direction where statistical inference

and formal reasoning systems live side-by-side and interact, prompt, inform and correct each other.

Integration of statistical inference and formal reasoning should be done in such a way to allow each of

the methods to independently and semi-redundantly but synergistically cooperate and potentially

enrich each other’s knowledge base (cross fertilization).

INVITED KEYNOTE SPEECH – 3

Wednesday, July 8, 9:00-10:00 / ROOM 1

Yannis Manolopoulos, Professor, Department of Informatics of the

Aristotle University of Thessaloniki

Title: Skyline Queries: an introduction

Abstract:

A case of preference queries that have attracted significant interest are the skyline queries, which have

been used in several multi-criteria decision support applications. Given a dominance relationship in a

dataset, a skyline query returns the objects that cannot be dominated by any other object. Skyline

queries have been studied extensively in multidimensional spaces, in subspaces, in high-dimensional

spaces, in metric spaces, in dynamic spaces, in streaming environments, and in time-series data.

Several algorithms have been proposed for skyline query processing: window-based, progressive,

distributed, geometric-based, index-based, divide-and-conquer, and dynamic programming

algorithms. Moreover, several variations of skyline queries have been proposed to solve application-

specific problems like: k-dominant skylines, top-k dominating queries, spatial skyline queries, and

others. As the number of objects that are returned in a skyline query may become large, there is also

an extensive study for the cardinality of skyline queries. We have studied the cardinality of skyline

and top-k dominating queries in multi-dimensional data, and we have proposed formulae for the

estimation of their cardinality. This extensive research depicts the importance of skyline queries and

their variations in modern applications.

INVITED KEYNOTE - 4

Wednesday July 8, 16:00 – 17:00 / ROOM 1

Stratis Kanarachos

Coventry University, UK

Title: Anomaly detection methods and applications in transportation

Abstract:

The last decade we have experienced a boom in sensor utilization and information collection. Sensors

and data acquisition systems have become cheap and widely available. Smartphones equipped with

sensors are being used almost everywhere. At the same the Internet of Things made possible to connect

devices, machines and structures through a network and exchange information between them. Of

particular significance is the timely and accurate exchange of safety critical information such as the

detection of damage or of abnormal operating conditions. The applications are vast, just to mention a

few: transportation, structural health monitoring, medicine, power distribution, economics. The normal

behaviour of machines and structures is described by data that follow regular time patterns.

Conversely, abnormal behaviour disturbs regularity and causes deviations from the regular time

pattern. Most of the anomaly detection algorithms proposed up to now are based on specific experts’

knowledge of the domain of interest. What becomes slowly and increasingly important is the

development of generic and widely applicable anomaly detection tools. In this presentation, we will

provide an overview of applications and methods used for this purpose.

Short bio:

Prof. Stratis Kanarachos graduated in 2001 from the Mechanical Engineering Course, National

Technical University of Athens (NTUA), Greece and he earned his Ph.D. degree from the same

institution in 2004. He held the position of Lecturer and Assistant Professor at Frederick University

scientific fields. As a result, new approaches try to resolve the resulting problems and at the same time

give more potential and robustness to next generation software applications.

This tutorial will introduce participants to the incorporation of both local and remote mobile databases

and particularly by using an Object Oriented architectural approach. During the tutorial some basic

mobile apps will be created and as a next step the resulting apps will be tested on an emulator and on

a real smartphone. We will make an introduction in SQLite local databases and in remote MySQL

databases. Our main focus will be in the Eclipse IDE and in the Android Operating System.

TUTORIAL – 2

Wednesday July 06, 17:30 – 18:30 / ROOM 2

Title: From Game Theory to Complexity, Emergence and Agent-Based

Modeling in World Politics

Presenter: John A. Paravantis

University of Piraeus, Greece.

Abstract:

This tutorial will examine the complexity of world politics with an emphasis on global environmental

issues. Concepts of game theory will be reviewed and connected to the state of international relations

(IR). Game theoretic models found in IR include the prisoner’s dilemma; game theoretic models

encountered in global environmental negotiations include the conflict between rich North and poor

South countries, the role of pollution havens and the clash of idealists versus pragmatists as well as

optimists versus pessimists. It will be suggested that the complexity of world politics, taking place on

a highly interconnected global network of actors organized as agents and meta-agents, is nothing but

a multiplayer extension of game theory although a complexity approach to world politics cannot be

regarded as a theory alternative to realism, but as a relatively novel research tool to aid with

understanding and anticipating (rather than predicting) global events. Technology, interconnections,

feedback and individual empowerment will be discussed in the context of the complex world of global

politics. Furthermore, evolution and adaptation will be related to the concept of fitness and how it may

be estimated for the case of actors in world politics. It will be suggested that many events of world

politics constitute emergent phenomena of the complex international community of state and non-state

actors. The tutorial will be complemented with a short overview of concepts related to agent-based

modeling (ABM), arguably the most prevalent method of simulating complex systems, and a review

of research problems from the fields of social science, political science, defense, world politics and the

global environment that have been successfully addressed with agent-based simulation. A list of

software resources useful to those who wish to address global problems with agent-based modeling

will be presented with examples programmed in a procedurial language and Netlogo. The main

conclusion will be that world politics may be considered a complex adaptive system (CAS) with states

being modelled as complex adaptive actors, i.e. agents, and international organizations such as the

United Nations or the EU being meta-agents. Understanding the system rules may be an important

aspect of analyzing the international system of states as a CAS by resorting to theoretical and ABM

tools in tandem.

TUTORIAL – 3

Wednesday July 07, 17:00 – 18:00 / ROOM 1

Title: New Trends in Virtual Reality and Augmented Visualization

Presenter: Lucio Tommaso De Paolis

Augmented and Virtual Reality Laboratory (AVR Lab)

Dept. of Engineering for Innovation

University of Salento, Italy

Abstract

Virtual Reality (VR) technology permits the creation of realistic-looking worlds where the user inputs

are used to modify in real time the digital environment. Interactivity and captivating power contribute

to the feeling of immersion in the virtual world, of being part of the action that the user experiences. It

is not only possible to see and manipulate the virtual objects, but also to feel and touch them using

specific devices.

The last few years have witnessed scientific advances in virtual reality, allowing virtual training

environments to get closer and closer to reality. Interesting learning situations can emerge with free

interaction in these simulated realities. In addition, the integration of pedagogical functions and

motivational aspects as in serious gaming and interactive storytelling, offers new possibilities for

training and allows the creation of relevant situations on the learning level.

Mixed Reality (MR) and Augmented Reality (AR) technologies permit the real-time fusion of

computer-generated digital contents with the real world and allow the creation of fascinating new types

of user interfaces. Augmented reality enhances the users' perception and improves their interaction in

the real environment. The virtual objects, displaying information that they cannot directly detect with

their own senses, help them to perform real-world tasks better.

Unlike the virtual reality technology that completely immerses users inside a synthetic environment

where they cannot see the real world around them, augmented reality technology allows to see 3-

dimensional virtual objects superimposed upon the real environment. Therefore, AR supplements

reality rather than completely replacing it; the user is under the impression that the virtual and real

objects coexist in the same space.

Many applications of VR and MR/AR technologies have been developed in different fields (medicine,

education, arts and cultural heritage, entertainment, military, and manufacturing). Recently, new

concepts such as Natural User Interfaces and Mobile Immersion have emerged and permit to combine

AR/MR technologies with new mobile human machine interfaces. Consequently, mobile immersion

will allow users to move away from purely physical communication mode to a mixed/augmented

reality communication, interaction and collaboration mode. Interactions will be natural and

augmentations will become ubiquitous.

Page 12: Professor George A. Tsihrintzis

11

The tutorial will present a review of current VR and AR technologies and will introduce to the

development and building of virtual environments and simulators. VR and AR applications in

medicine and surgery, cultural heritage, education and games will be described.

The aim of this tutorial is to bring a community of researchers from academia and industry, computer

scientists, engineers, physicians together in order to share points of views and emerging impressions

on the present applications of virtual reality and augmented reality technologies and discuss benefits

and limitations.

Abstract:

Car-like mobile robot navigation has been an active and challenging field both in academic research

and in industry over the last few decades, and it has opened the way to build and test (recently)

autonomously driven robotic cars which can negotiate the complexity and uncertainties introduced by

real outdoor urban and suburban environments. Our tutorial will start with a description of a very

popular and successful family of path planning algorithms, namely Rapidly-exploring Random Trees

(RRT). After discussing the great variety and modifications proposed for the basic RRT algorithm, we

turn our focus to versions which can address highly dynamic environments, and they have to be able

to take in account the constraints imposed by the Non-holonomic type of movement allowable for car-

like mobile robots. Finally, will conclude with some remarks and thoughts about the current state of

research and possible future developments.

Title: Towards Smart Energy Systems: An overview of existing tools and

future challenges

Presenter: Miltos Alamaniotis

School of Nuclear Engineering, Purdue University, USA

Abstract

This tutorial will present an overview of smart energy systems, and the challenges imposed in

developing smart energy technologies. Recent advancements in machine intelligence aim to address

challenges in diverse area of complex system engineering and its applications, such as advanced power

system safety. The data generated in these applications increases exponentially due to the penetration

of modern information technologies (internet) as well as their sensitive nature and need for accurate

and fast data processing and analysis. For instance, power systems and grids are monitored 24/7 by a

variety of different sensors aiming at predicting or diagnosing operational malfunctions. In such

environment, the limitations of human operators to follow and interpret the huge volume of data offer

opportunities for machine intelligence solutions to support effective and fast decision making.

Artificial intelligence tools such as fuzzy logic and artificial neural networks have been successfully

employed in the area of energy system control and safety. For example, in smart power systems

intelligent tools can reliably identify faults and estimate the remaining system life, while computational

intelligence methods are shown to accurately predict future electricity load demand as well as pricing

signals that may be used to direct demand at the level of appliances and devices in smart grids. An

overview of existing tools regarding advanced smart power systems will be presented and implications

for future research activities and challenges will be discussed.

Title: Advances in Adaptive Learning Using Fuzzy Logic in Student Model

Presenter: Konstantina Chrysafiadi

University of Piraeus, Greece

Abstract

In the past decade, there has been an enormous growth of the field of computer-based learning which

includes e-learning, mobile learning, educational games and standalone educational applications.

However, e-learning systems present several shortcomings, with regard to adaptivity problems, when

are compared to real-classroom education. Web-based educational systems offer easy access to

knowledge domains and learning processes from everywhere for everybody and at any time. As a

result, users of web-based educational systems are of varying backgrounds and they have

heterogeneous needs and abilities. Consequently, the challenge is to develop Web-based educational

systems that adapt dynamically to each individual student for effective delivery of the knowledge

domain.

A focus on the student model is essential for constructing an adaptive learning system that meets

students’ requirements. This tutorial will present important information about student modeling.

Initially, this tutorial will be referred to student modeling techniques and approaches that have been

used the past decade. Then, a novel student modeling approach including fuzzy logic techniques will

be presented. The presented student model maximizes the effectiveness of learning and contributes,

significantly, to the adaptation of the learning process to the learning pace of each individual learner.

It models either how learning progresses or how the student’s knowledge can be decreased, helping

the e-learning system to discover if the student learns or not, if s/he forgets, if s/he has difficulties in

understanding, if s/he assimilates the delivered knowledge. In other words, this tutorial will explain

how fuzzy logic can be used to automatically model the learning or forgetting process of a student.

Also, the particular tutorial will present the implementation of the presented fuzzy student model in a

web-based programming tutoring system that teaches the programming language ‘C’.
