To Adapt or Not to Adapt: A Quantification Technique for Measuring an Expected Degree of Self-Adaptation
Self-adaptation and self-organization (SASO) have been introduced to the management
of technical systems as an attempt to improve robustness and administrability. In particular, both
mechanisms adapt the system’s structure and behavior in response to dynamics of the environment
and internal or external disturbances. By now, adaptivity has been considered to be fully desirable.
This position paper argues that too much adaptation conflicts with goals such as stability and user
acceptance. Consequently, a kind of situation-dependent degree of adaptation is desired, which
defines the amount and severity of tolerated adaptations in certain situations. As a first step into this
direction, this position paper presents a quantification approach for measuring the current adaptation
behavior based on generative, probabilistic models. The behavior of this method is analyzed in
terms of three application scenarios: urban traffic control, the swidden farming model, and data
communication protocols. Furthermore, we define a research roadmap in terms of six challenges for
an overall measurement framework for SASO systems
Active Bird2Vec: Towards End-to-End Bird Sound Monitoring with Transformers
We propose a shift towards end-to-end learning in bird sound monitoring by
combining self-supervised (SSL) and deep active learning (DAL). Leveraging
transformer models, we aim to bypass traditional spectrogram conversions,
enabling direct raw audio processing. ActiveBird2Vec is set to generate
high-quality bird sound representations through SSL, potentially accelerating
the assessment of environmental changes and decision-making processes for wind
farms. Additionally, we seek to utilize the wide variety of bird vocalizations
through DAL, reducing the reliance on extensively labeled datasets by human
experts. We plan to curate a comprehensive set of tasks through Huggingface
Datasets, enhancing future comparability and reproducibility of bioacoustic
research. A comparative analysis between various transformer models will be
conducted to evaluate their proficiency in bird sound recognition tasks. We aim
to accelerate the progression of avian bioacoustic research and contribute to
more effective conservation strategies.Comment: Accepted @AI4S ECAI2023. This is the author's version of the wor
Socially-Sensitive Systems Design:Exploring Social Potential
In human society, individuals have long voluntarily organized themselves in groups, which embody, provide and/or facilitate a range of different social concepts, such as governance, justice, or mutual aid. These social groups vary in form, size, and permanence, but in different ways provide benefits to their members. In turn, members of these groups use their understanding and awareness of group expectations to help determine their own actions, to the benefit of themselves, each other, and the health of the group

On Learning in Collective Self-adaptive Systems: State of Practice and a 3D Framework
Collective self-adaptive systems (CSAS) are distributed and interconnected systems composed of multiple agents that can perform complex tasks such as environmental data collection, search and rescue operations, and discovery of natural resources. By providing individual agents with learning capabilities, CSAS can cope with challenges related to distributed sensing and decision-making and operate in uncertain environments. This unique characteristic of CSAS enables the collective to exhibit robust behaviour while achieving system-wide and agent-specific goals. Although learning has been explored in many CSAS applications, selecting suitable learning models and techniques remains a significant challenge that is heavily influenced by expert knowledge. We address this gap by performing a multifaceted analysis of existing CSAS with learning capabilities reported in the literature. Based on this analysis, we introduce a 3D framework that illustrates the learning aspects of CSAS considering the dimensions of autonomy, knowledge access, and behaviour, and facilitates the selection of learning techniques and models. Finally, using example applications from this analysis, we derive open challenges and highlight the need for research on collaborative, resilient and privacy-aware mechanisms for CSAS
Concepts for Resilient Traffic Management based on Organic Computing
This report aims at investigating forecast-based control of Organic Computing (OC) systems, especially the Organic Traffic Control (OTC) system. OTC is a self-organising traffic management system for urban road networks.
Making forecasts of future system states can make complex technical systems more robust against failures. We present concepts for the creation of forecasts at runtime and how these forecasts can be integrated in OC systems and OTC, and discuss how this can lead to higher resilience
