Abstract: IoT-enabled applications increase tremendously in various sectors, such as transportation, healthcare, education, agriculture, and so forth. These applications sense properties using sensors, perform intelligence, and apply the findings using actuators. Instead of submitting sensor data directly to the cloud, intelligence could be performed with the inclusion of several edge/fog nodes. This improves the privacy and computation time of applications. This talk will provide insights on edge intelligence techniques for such IoT-enabled applications. In addition, a few protocols that are involved in such applications are discussed.

Towards a Data-driven Identification of Teaching-Patterns

Friday, July 8, 2022 | 02:00 pm (CET) | Room: B01b.0.203, Lakeside Park

Jun. Prof. Dr. Bernhard Standl | Karlsruhe University of Education

Abstract: When it comes to integrating digital technologies into the classroom in higher education, many teachers face similar challenges. Nevertheless, it is difficult for teachers to share experiences because it is usually not possible to transfer successful teaching scenarios directly from one area to another, as subject-specific characteristics make it difficult to reuse them. To address this problem, instructional scenarios can be described as patterns that have been used previously in educational contexts. Patterns can capture proven teaching strategies and describe instructional scenarios in a consistent structure that can be reused. Because priorities for content, methods, and tools are different in each domain, a consensus-tested taxonomy was first developed with the goal of modeling a domain-independent database to collect digital instructional practices. In addition, this presentation will present preliminary insights into a data-driven approach to identifying effective instructional practices from interdisciplinary data as patterns. A web-based application will be developed for this that can both collect teaching/learning scenarios and individually extract scenarios from patterns for a learning platform.

Bio: Bernhard Standl is a tenure-track professor of Informatics Education at the Karlsruhe University of Education. His research focuses on modeling teaching concepts as pedagogical design patterns and on a data-driven identification of effective teaching-learning scenarios and their reuse in practice.

He received his Ph.D. in informatics education from the University of Vienna and where he was also active as a research assistant in educational projects and in a European Union’s funded project and research associate (post-doc) at the Vienna University of Technology.

Tipping Points and Inference in Complex Systems

Thursday, July 7, 2022 | 02:00 pm (CET) | Room: B4.1.114, Lakeside Park B04b, level 1

Professor Dr. rer. nat. Marc Timme | Strategic Professor & Chair for Network Dynamics TU Dresden, Germany

Abstract: The dynamics of networks enables the function of a variety of systems we rely on every day, from gene regulation and metabolism in the cell to the distribution of electric power and communication of information. Understanding, steering and predicting the function of interacting nonlinear dynamical systems, in particular if they are externally driven out of equilibrium, relies on obtaining and evaluating suitable models, posing at least two major challenges. First, how can we extract key structural system features of networks if only time series data provide information about the dynamics of (some) units?  Second, how can we characterize nonlinear responses of nonlinear multi-dimensional systems externally driven by fluctuations, and consequently, predict tipping points at which normal operational states may be lost? Here we report recent progress on nonlinear response theory extended to predict tipping points and on model-free inference of network structural features from observed dynamics.

This is work with Jose Casadiego, Mor Nitzan, Hauke Haehne, Georg Boerner, Moritz Thuemler and others.

The Computing Continuum: Beyond the Cloud Data Centers

Thursday, June 30th, 2022 | 10:00 (CET) | Room: S.2.69

Dr. Dragi Kimovski, MSc

Abstract: The advent of fog and edge computing has prompted predictions that they will take over the traditional cloud for information processing and knowledge extraction in Internet of Things (IoT) systems. Notwithstanding the fact that fog and edge computing have undoubtedly large potential, these predictions are probably oversimplified and wrongly portray the relations between cloud, fog and edge computing. 

Concretely, fog and edge computing have been introduced as an extension of the cloud services towards the data sources, thus forming the computing continuum. The computing continuum enables the creation of a new type of services, spanning across distributed infrastructures, supporting various IoT applications. These applications have a large spectrum of requirements, burdensome to meet with „distant“ cloud data centers. However, the introduction of the computing continuum raises multiple challenges for management, deployment and orchestration of complex distributed applications, such as: increased network heterogeneity, limited resource capacity of edge devices, fragmented storage management, high mobility of edge devices and limited support of native monolithic applications. These challenges primarily concern the complexity and the large diversity of the devices, managed by different entities (cloud providers, universities, private institutions), which range from single-board computers such as Raspberry Pis to powerful multi-processor servers.

Therefore, in this talk, we will discuss novel algorithms for low latency, scalable, and sustainable computing over heterogeneous resources for information processing and reasoning, thus enabling transparent integration of IoT applications. We will tackle the heterogeneity challenge of dynamically changing topologies of the computing infrastructure and present a novel concept for sustainable processing at scale.

CV: Dragi Kimovski is a  postdoctoral researcher at the Institute of Information Technology (ITEC), University of Klagenfurt, Austria. He earned his doctoral degree in 2013 from the Technical University in Sofia, Bulgaria. He was an assistant professor at  Ohrid University, N.

Abstract: We live in a “digital” world, the separation between physical and virtual makes (almost) no sense anymore. Here, the Corona pandemic has also acted as an accelerator/magnifier demonstrating that the future of our digital society is here with all its possibilities, but also shortcomings.
In his talk, Hannes Werthner will briefly reflect on the history of computer science, and then discuss the need for an interdisciplinary response to these shortcomings. Such an answer is the Digital Humanism, which looks at this interplay of technology and humankind, it analyzes, and, most importantly, tries to influence the complex interplay of technology and humankind, for a better society and life. In the second part he will discuss this approach, and show what was achieved since its first workshop in 2019, and what lies ahead.

Learning from and for Heterogeneous and Ambiguous Data

Wednesday, June 1st, 2022 | 10:00 am (CET) | Room: V.1.07

Univ.-Prof. DI Dr. Peter M. Roth | Prof. at Vetmeduni Wien

Abstract: When talking about new developments in Machine Learning, we typically think about new algorithms, better optimization techniques, or optimized hyperparameters. However, one important aspect is often neglected: the quality and the structure of training data: measurement noise, label noise, and correct but ambiguous labels. In this talk, we address the latter problem, trying to deal with high intra-class and small inter-class variability in the data, following two different strategies. First, we consider the problem of metric learning, showing that by selecting/learning a better metric for a specific problem, better results can be obtained: using the same learning method and the same data. Second, focusing on neural networks, we analyze the influence of specific hyperparameters, namely the activation functions. For both directions, we show that the quality of the finally learned model is highly dependent on the data. To illustrate these aspects, we will further discuss a visualization technique, namely information planes, providing better insights into the current state of the learning system.

Bio: He has been a professor at Vetmeduni Vienna since January 2022. Research interests include Data Science and Machine Learning.
