Prof. Carsten Griwodz 

Networks and Distributed Systems | University of Oslo

MishMash role: Work Package Leader Group member

Abstract: This talk will introduce the research of SINLab, the Sustainable Immersive Networking Lab, at the University of Oslo. Our applications are diverse, and range from music making to working on assembly lines, and also our investigations range from the efficient parallelization of media-specific algorithms to quantitative user experiences. Through all of this, we explore how humans perceive audiovisual and tactile experiences. Our research questions are concerned with the disconnect between local environments and those that are remote in time and space. We answer questions like: „To which extent can Redirected Walking help you to experience unconstrained virtual worlds through natural movement?” and “How can we overcome the delay challenges when you act remotely in first person through a robot arm and hand?”. My talk will introduce these questions in some detail and give an overview of our findings so far.

Prof. Hui Yong Kim | Dept. of Computer Science and Engineering and Dept. of Artificial Intelligence | Kyung Hee University

Abstract: Up to now, video coding standards have been developed as a combinatory set of a large number of coding tools. Each tool was primarily based on signal-processing algorithms or experimental optimizations. Recently, a new paradigm called Learned Video Coding (LVC), a.k.a. Neural Network-based Video Coding (NNVC), has emerged. By exploiting the end-to-end training with a large number of video datasets, some representative models already outperform the latest video coding standard, VVC (Versatile Video Coding). In this talk, the LVC technology will be briefly outlined and then the opportunities and remaining challenges will be discussed.

Dr. Rudy Kuhn | Lead Evangelist at Celonis

Abstract: Künstliche Intelligenz ist gerade überall. Sie verspricht Effizienz, Automatisierung und die nächste große Revolution. Aber hier ist die unbequeme Wahrheit: Die meisten Unternehmen wissen gar nicht, wie ihre Prozesse wirklich funktionieren. Und genau deshalb scheitert KI häufiger, als wir zugeben. Denn KI ist nur so gut wie die Prozesse, auf denen sie aufsetzt. Wenn diese intransparent, ineffizient oder schlicht falsch verstanden sind, automatisieren wir vor allem eines: Chaos.

Genau hier kommt Process Mining & Intelligence ins Spiel. Die von Prof. Dr. Wil van der Aalst entwickelte Technologie macht sichtbar, was tatsächlich passiert – nicht das, was wir glauben oder dokumentiert haben. Unternehmen weltweit nutzen Process Intelligence, um Transparenz zu schaffen, bessere Entscheidungen zu treffen und echten Mehrwert zu generieren. Die Firma Celonis aus München gilt als Marktführer in diesem Bereich. Rudy Kuhn, einer ihrer erfahrensten Experten für Process Intelligence, Automatisierung und KI, lebt seit einigen Jahren in unmittelbarer Nähe der Universität Klagenfurt und wird in seinem Vortrag zeigen, warum es keine Künstliche Intelligenz ohne Process Intelligence gibt – und was das konkret für die Zukunft von Unternehmen bedeutet.

Bio: Als Lead Evangelist bei Celonis inspiriert Rudy Kuhn Kunden, Partner und Analysten dazu, ihre Geschäftsabläufe unter dem Gesichtspunkt von Process Intelligence, Automatisierung und Orchestrierung neu zu gestalten. Mit über 25 Jahren Erfahrung in der Prozessoptimierung und -transformation sowie 16 Jahren tiefgreifender Beschäftigung mit Process Mining hat er seine Karriere darauf ausgerichtet, Unternehmen dabei zu unterstützen, das volle Potenzial ihrer durchgängigen Prozesse auszuschöpfen. Vom Aufbau des ersten E-Business-Beratungsteams von IBM in Deutschland über die Gründung von ProcessGold und die Einführung von Process Mining bei UiPath bis hin zu seiner aktuellen Rolle bei Celonis – Rudy stand und steht weiterhin an der Spitze der digitalen Transformation.

Dr. Hadi Amirpourazarian | Department of Information Technology

Abstract: Video coding is the beating heart of multimedia communication, and despite decades of innovation, it remains a field full of challenges and opportunities. While much research continues to push codec-level efficiency, this talk shifts the perspective to video streaming: how smart decisions about encoding parameters can dramatically boost real-world delivery performance. We explore how content-adaptive bitrate ladders unlock substantial efficiency gains by tailoring encoding settings to each video’s unique characteristics, and how optimizing bitrate, resolution, and frame rate can balance conflicting goals such as visual quality, delivery cost, and energy consumption. We then dive into how these strategies can be brought to life in live streaming using powerful video-complexity analysis frameworks. Finally, we reveal how real-time quality measurement enables intelligent, responsive streaming systems that elevate video delivery and monitoring to a new level.

Bio: Hadi Amirpour is working on adaptive video streaming, image/video compression, QoE evaluation, 3D and immersive imaging, and machine-learning-based medical image analysis, with a focus on translating theory into next-generation multimedia systems. He has received multiple distinctions, including Best Paper Awards (PCS 2024, NAB 2025) and Grand Challenge wins at ICIP 2024 and VCIP 2025. He contributes to JPEG Pleno and MPEG standardization on light fields, point clouds, and immersive formats, and has co-chaired Qualinet Task Force 7 since 2021, advancing subjective and objective video quality assessment. He is an Associate Editor for IEEE TCSVT and holds key leadership roles such as TPC Co-Chair of VCIP 2025 and General Co-Chair of QoMEX 2026 and MMSP 2027. He is also active in organizing special sessions, workshops, and tutorials at major venues, including IEEE ICME, IEEE QoMEX, ACM Multimedia, VQEG, EUVIP, and ACM MobiSys.

Abstract: DDoS attacks are one of the currently most pressing cybersecurity problems. In these attacks, attackers flood their targets with unwanted traffic to exhaust the available resources, e.g., bandwidth. Over time, DDoS attack volumes became record-hitting terabit-level attacks that can even challenge the largest networks on the Internet. In this talk, we focus on exploring the types of attack vectors, including booter services that enable everyone to launch attacks, and present mitigation techniques that can be employed within IXPs.
