Speech Title: Medical Image Segmentation Approaches for Diagnostic Analytics
Abstract: Humans have a strong ability to process millions of data and information to assist in the decision-making process. With new disruptive technology, a trillion of medical data has been flooded into cloud computing and require an analytical process to produce valuable diagnosis information. Images are one of the data collected using a variety of sensors that carry a lot of valuable information for the diagnosis process. Therefore, Medical Image Diagnostic Analytics is a very significant research area to be strengthened in the new era of Big Data to improve healthcare industries by providing reliable information. The most important process in Medical Image Analytics is image segmentation. Image segmentation is to extract clinically relevant information with intelligent insight. There are several methods can be used in the segmentation process. In this discussion, several image segmentation methods will be presented. The advantages and disadvantages of each method are described besides examination of each algorithm with its application in Magnetic Resonance Imaging and Computed Tomography image analysis. Each algorithm is explained separately with its ability and features for the analysis of grey-level images. In order to evaluate the segmentation results, some popular benchmark measurements also presented in the final section. In this keynote, the discussion also focuses on experiences in Medical Image Diagnostic A
nalytics and discussing key challenges in various types of data for further research including semantic gaps.

Speech Title: Algorithms for Travelings Salesman Problems with Drones
Abstract: The use of drones in logistics is gaining more and more interest. In this presentation we consider the flying sidekick traveling salesman problem, where a set of customers requires a delivery and deliveries can be served either by a truck or by a drone. The aim is minimizing the total time required to service all the customers. In this talk we discuss some algorithms based on branch and bound for the problem. A first contribution is an exact algorithm characterized by not completely specified solutions in the search tree, that are later fully determined by solving an Assignment Problem. Such a choice limits the size of the search tree, but on the other hand tends to weaken lower bounds. Experimental results show that the choice pays off for instances of limited size, leading to very good and consistent results in terms of speed for instances up to 10-15 customers. Note that these results are in line with the current literature. The same branch and bound algorithm is also effectively used as a subroutine for a heuristic algorithm, which is the second contribution of this work. The idea is to iteratively optimize overlapping chunks of a solution with the exact algorithms. Again, experimental results prove that such a heuristic approach is extremely competitive on large instances, being able to effectively deal with instances with up to 229 customers in a operatively short time, representing the current state-of-the-art.

Speech Title: Nurturing Computational Thinking Skills: An Adaptive Approach
Abstract: The fourth industrial revolution bring changes in terms of technologies and a major shift in the job environment. One of the important skills can be promoted with this revolution is computational thinking (CT) skills. CT is a vital and fundamental skill which involved solving problems activities, designing system, and also understanding human behavior by mapping the concepts into computer science discipline.

The Covid-19 pandemic have demanded the education system to utilize the digital platform in ensuring that the teaching-learning process can be conducted amid the pandemic. Thus, in this sense, ubiquitous learning is a learning environment to support digital learning paradigm. The overall purpose of this presentation is to share an adaptive approach to nurture students’ CT skills in ubiquitous learning environment. The approach enables students to have better opportunity in learning CT concepts and exploring various methods and technologies used in education including gamification and educational robotics.

Speech Title: Cooperation Enforcement and Collusion Resistance in Repeated Public Goods Games
Abstract: Enforcing cooperation among substantial agents is one of the main objectives for multi-agent systems. However, due to the existence of inherent social dilemmas in many scenarios, the free-rider problem may arise during agents' long-run interactions and things become even severer when self-interested agents work in collusion with each other to get extra benefits. It is commonly accepted that in such social dilemmas, there exists no simple strategy for an agent whereby she can simultaneously manipulate on the utility of each of her opponents and further promote mutual cooperation among all agents. Here, we show that such strategies do exist. Under the conventional repeated public goods game, we novelly identify them and find that, when confronted with such strategies, a single opponent can maximize his utility only via global cooperation and any colluding alliance cannot get the upper hand. Since a full cooperation is individually optimal for any single opponent, a stable cooperation among all players can be achieved. Moreover, we experimentally show that these strategies can still promote cooperation even when the opponents are both self-learning and collusive.

Speech Title: Quantum-based Technology in Cyber Defense
With the rapid development of computer and network, new technologies and services are being generated, evolved, and promoted constantly, bringing great convenience and changes to people’s life. Over the next 5-10 years, we will see a flux of new possibilities, as quantum technologies become part of this mainstream computing and communicating landscape.

All security concepts, such as authentication, encryption but also more involved concepts as computation on encrypted data and secure multiparty computation, would need to be modified to apply to quantum information and quantum computation. Quantum technologies can offer advantages for cyber security research. To view this positive aspect, we should consider the possibility of including quantum steps in protocols with the aim of achieving certain improvement compared to the corresponding fully classical setting.

This presentation will explore quantum-technology solutions in the 21st century and their role in cyber security. The speaker will also share the most relevant results of the projects she has worked on.
