It is targeted at\r\nheterogeneous and expensive problems, i.e., problems that have at least one\r\nobjective function that is computationally expensive. The method is\r\nderivative-free in the sense that neither need derivative information be\r\navailable for the expensive objectives nor are gradients approximated using\r\nrepeated function evaluations as is the case in finite-difference methods.\r\nInstead, a multiobjective trust region approach is used that works similarly to\r\nits well-known scalar pendants. Local surrogate models constructed from\r\nevaluation data of the true objective functions are employed to compute\r\npossible descent directions. In contrast to existing multiobjective trust\r\nregion algorithms, these surrogates are not polynomial but carefully\r\nconstructed radial basis function networks. This has the important advantage\r\nthat the number of data points scales linearly with the parameter space\r\ndimension. The local models qualify as fully linear and the corresponding\r\ngeneral scalar framework is adapted for problems with multiple objectives.\r\nConvergence to Pareto critical points is proven and numerical examples\r\nillustrate our findings.","lang":"eng"}],"publication":"Mathematical and Computational Applications","title":"Derivative-Free Multiobjective Trust Region Descent Method Using Radial  Basis Function Surrogate Models","date_created":"2021-03-01T10:46:48Z","year":"2021","issue":"2"},{"date_created":"2021-03-01T11:52:08Z","author":[{"first_name":"Marc","id":"71302","full_name":"Wende, Marc","last_name":"Wende"},{"full_name":"Kenig, Eugeny","id":"665","last_name":"Kenig","first_name":"Eugeny"}],"date_updated":"2022-01-06T06:54:55Z","conference":{"location":"Online-Konferenz","end_date":"2021-02-26","start_date":"2021-02-24","name":"Jahrestreffen der ProcessNet-Fachgruppen Fluidverfahrenstechnik und Wärme- und Stoffübertragung"},"title":"Konzeption und Inbetriebnahme eines Versuchsstandes zur Gravidestillation","citation":{"apa":"Wende, M., &#38; Kenig, E.

The detection principle is based on a secondary electron conversion holder with an exchangeable aperture strip allowing its acceptance angle to be tuned from 3 to 98 mrad. The contrast mechanism and performance were investigated using freestanding nanometer-thin carbon membranes. The results demonstrate that the detector can be optimized either for most efficient signal collection or for maximum image contrast. The designed setup allows for the imaging of thin low-density materials that otherwise provide little signal or contrast and for a clear end-point detection in the fabrication of nanopores. In addition, the detector is able to determine the thickness of membranes with sub-nanometer precision by quantitatively evaluating the image signal and comparing the results with Monte Carlo simulations. The thickness determined by the dark-field transmission detector is compared to X-ray photoelectron spectroscopy and energy-filtered transmission electron microscopy measurements.</jats:p>"}],"user_id":"77496","department":[{"_id":"286"},{"_id":"321"},{"_id":"15"},{"_id":"9"}],"_id":"21374","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2190-4286"]},"citation":{"bibtex":"@article{Emmrich_Wolff_Meyerbröker_Lindner_Beyer_Gölzhäuser_2021, title={Scanning transmission helium ion microscopy on carbon nanomembranes}, DOI={<a href=\"https://doi.org/10.3762/bjnano.12.18\">10.3762/bjnano.12.18</a>}, journal={Beilstein Journal of Nanotechnology}, author={Emmrich, Daniel and Wolff, Annalena and Meyerbröker, Nikolaus and Lindner, Jörg and Beyer, André and Gölzhäuser, Armin}, year={2021}, pages={222–231} }","short":"D.

In contrast to other autonomous vehicle applications, WSNs have two metrics for performance evaluation. First, quality of information (QoI) which is used to measure the quality of sensed data (e.g., measurement uncertainties or signal strength). Second, quality of service (QoS) which is used to measure the network's performance for data forwarding (e.g., delay and packet losses). As a use case, we consider wireless acoustic sensor networks, where a group of speakers move inside a room and there are autonomous vehicles installed with microphones for streaming the audio data. We formulate the problem as a Markov decision problem (MDP) and solve it using Deep-Q-Networks (DQN). Additionally, we compare the performance of DQN solution to two different real-world implementations: speakers holding/passing microphones and microphones being preinstalled in fixed positions. We show that the performance of autonomous vehicles in terms of QoI and QoS is better than the real-world implementation in some scenarios. Moreover, we study the impact of the vehicles speed on the learning process of the DQN solution and show how low speeds degrade the performance. Finally, we compare the DQN solution to a heuristic one and provide theoretical analysis of the performance with respect to dynamic WSNs."}],"user_id":"65718","_id":"21478","project":[{"name":"Akustische Sensornetzwerke - Teilprojekt \"Verteilte akustische Signalverarbeitung über funkbasierte Sensornetzwerke","_id":"27"}],"language":[{"iso":"eng"}]},{"citation":{"apa":"Afifi, H., Ramaswamy, A., &#38; Karl, H.

In this paper, we consider an example of wireless acoustic sensor networks, where we select a subset of microphones for two different objectives. First, we maximize the recording quality under QoS constraints. Second, we apply a trade-off between QoI and QoS. We formulate the problem as a constrained Markov Decision Problem (MDP) and solve it using reinforcement learning (RL). We compare the RL solution to a baseline model and show that in case of QoS-guarantee objective, the RL solution has an optimality gap up to 1\\%. Meanwhile, the RL solution is better than the baseline with improvements up to 23\\%, when using the trade-off objective.","lang":"eng"}],"user_id":"65718","_id":"21479","project":[{"name":"Akustische Sensornetzwerke - Teilprojekt \"Verteilte akustische Signalverarbeitung über funkbasierte Sensornetzwerke","_id":"27"}],"language":[{"iso":"eng"}],"keyword":["reinforcement learning","wireless sensor networks","resource allocation","acoustic sensor networks"]},{"year":"2021","citation":{"ama":"Gutt D, Neumann J, Jabr W, Kundisch D.

Providing these services requires online coordination including scaling the service, placing instance of all components in the network, scheduling traffic to these instances, and routing traffic through the network. Optimized service coordination is still a hard problem due to many influencing factors such as rapidly arriving user demands and limited node and link capacity. Existing approaches to solve the problem are often built on rigid models and assumptions, tailored to specific scenarios. If the scenario changes and the assumptions no longer hold, they easily break and require manual adjustments by experts. Novel self-learning approaches using deep reinforcement learning (DRL) are promising but still have limitations as they only address simplified versions of the problem and are typically centralized and thus do not scale to practical large-scale networks.\r\n\r\nTo address these issues, we propose a distributed self-learning service coordination approach using DRL. After centralized training, we deploy a distributed DRL agent at each node in the network, making fast coordination decisions locally in parallel with the other nodes. Each agent only observes its direct neighbors and does not need global knowledge. Hence, our approach scales independently from the size of the network. In our extensive evaluation using real-world network topologies and traffic traces, we show that our proposed approach outperforms a state-of-the-art conventional heuristic as well as a centralized DRL approach (60% higher throughput on average) while requiring less time per online decision (1 ms)."}],"file":[{"file_id":"21544","file_name":"public_author_version.pdf","access_level":"open_access","file_size":606321,"title":"Distributed Online Service Coordination Using Deep Reinforcement Learning","date_created":"2021-03-18T17:12:56Z","creator":"stschn","date_updated":"2021-03-18T17:12:56Z","relation":"main_file","content_type":"application/pdf"}],"keyword":["network management","service management","coordination","reinforcement learning","distributed"],"ddc":["000"],"language":[{"iso":"eng"}]}]
