Providing such services requires to decide how often to instantiate each component, where to place these instances in the network, how to chain them and route traffic through them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep reinforcement learning (DRL) approaches for self-learning network and service management have emerged recently. These model-free DRL approaches are more flexible but typically learn tabula rasa, i.e., disregard existing understanding of networks, services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel model-based AI approach that leverages existing understanding of networks and services for more efficient and effective coordination without time-intensive training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic model. This allows FutureCoord to estimate the impact of future incoming traffic and effectively optimize long-term effects, taking fluctuating demand and Quality of Service (QoS) requirements into account. Our extensive evaluation based on real-world network topologies, services, and traffic traces indicates that FutureCoord clearly outperforms state-of-the-art model-free and model-based approaches with up to 51% higher flow success ratios.","lang":"eng"}],"author":[{"last_name":"Werner","full_name":"Werner, Stefan","first_name":"Stefan"},{"id":"35343","full_name":"Schneider, Stefan Balthasar","orcid":"0000-0001-8210-4011","last_name":"Schneider","first_name":"Stefan Balthasar"},{"first_name":"Holger","full_name":"Karl, Holger","id":"126","last_name":"Karl"}],"date_updated":"2022-01-11T08:44:04Z","oa":"1","conference":{"end_date":"2022-04-29","location":"Budapest","name":"IEEE/IFIP Network Operations and Management Symposium (NOMS)","start_date":"2022-04-25"},"has_accepted_license":"1","citation":{"apa":"Werner, S., Schneider, S.

Due to simplifications and the model-reality-gap physics-derived models frequently exhibit deviations from real-world-systems. Likewise, purely data-driven methods often do not generalise well enough and may violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired loss functions separately have shown promising results to conquer these drawbacks. In this contribution we extend existing methods towards the identification of non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN and a physics-inspired loss term (-L) to successfully identify the system's dynamics, while maintaining the consistency with physical laws. The proposed method is demonstrated on two real-world nonlinear systems and outperforms existing techniques regarding complexity and reliability.","lang":"eng"}],"status":"public","_id":"26539","user_id":"43992","department":[{"_id":"153"},{"_id":"880"}],"keyword":["data-driven","physics-based","physics-informed","neural networks","system identification","hybrid modelling"],"language":[{"iso":"eng"}]},{"type":"conference","status":"public","user_id":"43992","department":[{"_id":"153"},{"_id":"880"}],"_id":"31066","citation":{"ama":"Schön O, Götte R-S, Timmermann J.

During this process, the company has to validate various hypotheses about its business models by adapting to uncertain and changing customer needs effectively and efficiently. This adaptation, in turn, can be supported by the concept of Software Product Lines (SPLs). SPLs reduce the time to market by deriving products for customers with changing requirements using a common set of features, structured as a feature model. Analogously, we support the process of business model adaptation by applying the engineering process of SPLs to the structure of the Business Model Canvas (BMC). We call this concept a Business Model Decision Line (BMDL). The BMDL matches business domain knowledge in the form of a feature model with customer needs to derive hypotheses about the business model together with experiments for validation. Our approach is effective by providing a comprehensive overview of possible business model adaptations and efficient by reusing experiments for different hypotheses. We implement our approach in a tool and illustrate the usefulness with an example of developing business models for a mobile application.","lang":"eng"}],"file":[{"file_id":"17383","access_level":"open_access","file_name":"CBI.pdf","file_size":569290,"date_created":"2020-07-14T09:33:00Z","creator":"sego","date_updated":"2020-07-14T09:33:00Z","relation":"main_file","content_type":"application/pdf"}],"publication":"Proceedings of the 22nd IEEE International Conference on Business Informatics","keyword":["Business Model Decision Line","Business Model Adaptation","Hypothesis-driven Adaptation","Software Product Line","Feature Model"],"ddc":["006"],"language":[{"iso":"eng"}]},{"publication_identifier":{"isbn":["978-1-4503-1346-9"]},"year":"2012","place":"New York, NY, USA","page":"117-122","citation":{"ieee":"M.

In the present issue one article presents an improved methodology for disentangling perceptual and temporal influences in markers. Another paper demonstrates that preemptive control, or DPS, mediates the allocation of attention towards possible targets. One of the contributions specify conditions under which DPS-like effects are found as opposed to conditions under which stimulus-driven effects are found. A study of two illusions which the prime may cause in a trailing stimulus, a temporal pre-dating of the mask and a perception of motion in later stimuli adjacent to the prime is presented in the issue. Another contribution addresses how the percept of a stimulus is altered by a temporal and spatial interplay of two backward masks or of one forward mask and two backwards masks.
