Transparency by Design (Dagstuhl Seminar 21231)

Authors: Judy Kay, Tsvi Kuflik, and Michael Rovatsos


Abstract
This report documents the program and outcomes of Dagstuhl Seminar 21231 on "Transparency by Design" held in June 2021. Despite extensive ongoing discussions surrounding fairness, accountability, and transparency in the context of ethical issues around AI systems that are having an increasing impact on society, the notion of transparency - closely linked to explainability and interpretability - has largely eluded systematic treatment within computer science to date. The purpose of this Dagstuhl Seminar was to initiate a debate around theoretical foundations and practical methodologies around transparency in data-driven AI systems, with the overall aim of laying the foundations for a "transparency by design" framework – a framework for systems development methodology that integrates transparency in all stages of the software development process. Addressing this long-term challenge requires bringing together researchers from Artificial Intelligence, Human-Computer Interaction, and Software Engineering, as well as ethics specialists from the humanities and social sciences, which was a key objective for the four-day seminar conducted online.

Human-Computer Interaction to Support Work and Wellbeing in Mobile Environments (Dagstuhl Seminar 21232)

Authors: Stephen Brewster, Andrew Kun, Andreas Riener, and Orit Shaer


Abstract
We are living in a world where ubiquitous computing devices are becoming parts of the fabric of our lives. At work and at school, devices such as calculators, tablet computers, mobile phones, and different electronic measurement devices, support our work and learning. Building on all of these technological advancements will be novel human-computer interaction techniques that will allow us to use the devices for work and play in a broad set of circumstances, from riding in automated vehicles, to exploring museums, to walking on the street, to playing with our kids on the beach. The central underlying question Dagstuhl seminar 21232 wanted to address is, "how will we interact with the ubiquitous devices of our near (and not-so-near) future?" To date, there are a number of interaction techniques that show significant promise, including speech, augmented reality, tangible objects, gesture, multitouch screens, as well as simple keyboards and non-touch displays. But, before we address technologies to use, we must first identify the economic and broad societal driving forces that will create the need for interaction with our ubiquitous computing devices. From the economic point of view worker well-being is one such driving force; another one is the need to improve the productivity of workers and firms; yet another is the need to provide access to continuous education to a changing workforce. From the broad perspective of our society, it is important for us to understand how ubiquitous technologies can support living a meaningful and fulfilling life, from childhood to adulthood. In the following, we report the program, activities, and the outcomes of Dagstuhl Seminar 21232 "Human-Computer Interaction to Support Work and Wellbeing in Mobile Environments".

Compute-First Networking (Dagstuhl Seminar 21243)

Authors: Jon Crowcroft, Philip Eardley, Dirk Kutscher, and Eve M. Schooler


Abstract
A Dagstuhl seminar on Compute-First Networking (CFN) was held online from June 14th to June 16th 2021. We discussed the opportunities and research challenges for a new approach to in-network computing, which aims to overcome limitations of traditional edge/in-network computing systems. The seminar discussed relevant use cases such as privacy-preserving edge video processing, connected and automated driving, and distributed health applications leveraging federated machine learning. A discussion of research challenges included an assessment of recent and expected future developments in networking and computing platforms and the consequences for in-network computing as well as an analysis of hard problems in current edge computing architectures. We exchanged ideas on a variety of research topics and about the results of corresponding activities in the larger fields of distributed computing and network data plane programmability. We also discussed a set of suggested PhD topics and promising future research directions in the CFN space such as split learning that is supported by in-network computing.

Quantum Complexity: Theory and Application (Dagstuhl Seminar 21261)

Authors: Bill Fefferman, Sevag Gharibian, Norbert Schuch, and Barbara Terhal


Abstract
This report documents the program and outcomes of Dagstuhl Seminar 21261 "Quantum Complexity: Theory and Application". The seminar ran from June 27 to July 2 , 2021, and was held in a hybrid format (due to COVID travel restrictions). Of the 55 total participants from 14 countries, 17 participants were on-site, and 38 were remote. Recent advances in both theoretic and experimental aspects of quantum complexity theory were presented and discussed, ranging from new theoretical developments via a "Quantum Strong Exponential Time Hypothesis", to more experimentally oriented talks involving benchmarking of random circuits in quantum supremacy experiments. In addition, an open problem session and a discussion session regarding the current state of the field were included.

Inter-Vehicular Communication - From Edge Support to Vulnerable Road Users (Dagstuhl Seminar 21262)

Authors: Ana Aguiar, Onur Altintas, Falko Dressler, and Gunnar Karlsson


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 21262 "Inter-Vehicular Communication - From Edge Support to Vulnerable Road Users". Looking back at the last decade, one can observe enormous progress in the domain of vehicular networking. In this growing community, many ongoing activities focus on the design of communication protocols to support safety applications, intelligent navigation, and many others. We shifted the focus from basic networking principles to open challenges in edge computing support and, as a novel aspect, on how to integrate so called vulnerable road users (VRU) into the picture.
