Speech Title: Intelligent Transportation: Learning in real-time from distributed data

Abstract: Intelligent Transportation is the primordial example of a Cyberphysical System (CPS), that encapsulates a very large network of “smart” devices (possessing sensing, communication, and computation capabilities) controlling physical entities. Besides, the ever-emerging paradigm of AIoT targets solutions that capitalize the computational power of Internet-of-Things (IoT) devices to enable Artificial Intelligence (AI) in system operations.
This keynote will discuss the CPS/AIoT perspective to Intelligent Transportation, which considers real-time learning in a network of agents with distributed data collection. In specific, I will discuss two problems:
a) Real-time learning of travel time densities via online Sparse Kernel Density Estimation
b) Real-time 3D Multi-Object Detection & Tracking from LiDAR point clouds

Speech Title: Trustworthy Artificial Intelligence of Things

Abstract: Artificial Intelligence (AI) and Internet of Things (IoT) are very important technologies for the future and there are a lot of research activities to combine AI and IoT, called AIoT (Artificial Intelligence of Things). Furthermore, data is becoming essential to support AI based solutions with human interactions. In this regard, this talk introduces key concepts, features and characteristics of human centric AIoT in data driven networking point of view. From AIoT research, many researchers have identified that there are security, privacy and trust concerns to realize human-centric AIoT. To cope with negative effects of AIoT, it’s necessary to address trustworthy AIoT. Therefore, this talk introduces data ecosystem and its features. Then, it presents key challenges for realizing trustworthy AIoT and discuss next steps for future research.

Speech Title: The Effectiveness of Bidding Support in Negotiation

Abstract: We present a dependency analysis and a categorization of future and existing economic decision support mechanisms for negotiation. Our survey suggests that active mechanisms would be more effective than passive ones, and that implicit mechanisms can shield the user from mathematical complexities. We discuss results of empirical studies of the effectiveness of the bidding support mechanisms of the Pocket Negotiator, an economic decision support system.
Furthermore, we discuss the open challenges, and report about the community efforts as can be seen from the Annual Negotiating Agents Competition.

Biography: Catholijn Jonker (1967) is full professor of Interactive Intelligence at the Faculty of Electrical Engineering, Mathematics and Computer Science of the Delft University of Technology. Jonker studied computer science, and did her PhD studies at Utrecht University. After a post-doc position in Bern, Switzerland, she became assistant (later associate) professor at the Department of Artificial Intelligence of the Vrije Universiteit Amsterdam. From September 2004 until September 2006 she was a full professor of Artificial Intelligence / Cognitive Science at the Nijmegen Institute of Cognition and Information of the Radboud University Nijmegen. She chaired De Jonge Akademie (Young Academy) of the KNAW (The Royal Netherlands Society of Arts and Sciences) in 2005 and 2006, and she was a member of the same organization from 2005 to 2010. She is a member of the Koninklijke Hollandsche Maarschappij der Wetenschappen andof the Academia Europaea. She was the president of the National Network Female Professors (LNVH) in The Netherlands from September 2013 till January 2016. She served TU Delft for one year as interim head of department for the Design Engineering Department (2014/2015). Catholijn is EurAI Fellow since 2015, and EurAI board member since 2016, EurAI is the European Association for Artificial Intelligence.
Her publications address cognitive processes and concepts such as negotiation, teamwork and the dynamics of individual agents and organizations. In all her research lines Catholijn has adopted a value-sensitive approach. In particular, she works towards intelligent agents that can interact with their users in value-conflicting situations when also meta-values no longer solve the situation. In Delft she works with an interdisciplinary team to create synergy between humans and technology by understanding, shaping and using fundamentals of intelligence and interaction. End 2007 her NWO-STW 1.5 M€ VICI project “Pocket Negotiator” has been awarded. In this project she develops intelligent decision support systems for negotiation.

Speech Title: Progress and Open Questions of Convolutional Neural Networks

Abstract: Artificial intelligence and machine learning algorithms have become a core of numerous applications used in medicine, security, agriculture, astronomy, and many more. In general, these applications require a classification method, usually for the classification of digital images. In decades of intensive study of the classification problem, various classification methods were proposed and used. However, in recent years, the convolutional neural networks have proven to be a far better method for certain classification problems and have brought some revolutionary changes in certain areas. Convolutional neural networks (CNNs) are the type of deep artificial neural networks that manage to significantly improve classification accuracy, especially of digital images. Using, creating and training CNN is a relatively simple task due to the various available software tools, but the problem with CNNs is finding the optimal configuration and architecture. Designing and tuning CNN represents a very challenging problem that should be dealt with in order to achieve the best possible results. The optimal CNN’s configuration depends on the considered problem and one CNN that is good for one problem is not necessarily good for others. Finding the optimal configuration is not a simple task since there are numerous hyperparameters such as the number, type and order of layers, number of neurons in each layer, kernel size, optimization algorithm, padding, stride, and many others, that should be fine-tuned for each classification problem. There is no unique efficient method for finding optimal values of CNNs’ hyperparameters. A commonly used method for setting the CNN’s configuration is to guess good starting values and estimate better values for the hyper-parameters (guestimating). This method is simple but not the most efficient. Since this is an optimization problem, some recent studies tested different optimization metaheuristics such as swarm intelligence algorithms. Usage of swarm intelligence algorithms for finding CNNs’ configuration can be time consuming but the improvement of the classification accuracy is significant. In this talk, the advantages and challenges of finding the optimal CNN configuration will be presented.
