Typical concepts in development management like the application of safety coefficients imply limitations of the solution space. In contrast, explicit handling of uncertainties can support engineers in understanding the problem space and in utilising the full potential of the design space along iterative product development steps. As a result from literature analysis, there is a lack of a support for product development that addresses the specific problem of uncertainty and risk in the context of requirement changes. The aim of the contribution at hand is to enhance the efficient development of complex interdisciplinary systems by enabling uncertainty handling in requirements change management. Based on a classification of uncertainty types resulting in a descriptive model, risk management measures are identified to support requirements engineers. The proposed method includes identification &amp; modelling, analysis, treatment and monitoring of risks and counter-measures. By applying this method, engineers are supported in adopting agile approaches and enabling flexible Requirements Engineering.</jats:p>","lang":"eng"}],"publication":"Proceedings of the Design Society","doi":"10.1017/pds.2021.430","conference":{"location":"Gothenburg","end_date":"2021-08-20","start_date":"2021-08-16","name":"23nd International Conference on Engineering Design (ICED21)"},"author":[{"first_name":"Iris","orcid":"0000-0001-5765-971X","last_name":"Gräßler","full_name":"Gräßler, Iris","id":"47565"},{"first_name":"Jens","orcid":"http://orcid.org/0000-0001-8778-2989","last_name":"Pottebaum","full_name":"Pottebaum, Jens","id":"405"},{"first_name":"Christian","full_name":"Oleff, Christian","id":"41188","last_name":"Oleff","orcid":"0000-0002-0983-1850"},{"first_name":"Daniel","last_name":"Preuß","id":"40253","full_name":"Preuß, Daniel"}],"volume":1,"date_updated":"2023-11-16T09:21:03Z","citation":{"apa":"Gräßler, I., Pottebaum, J., Oleff, C., &#38; Preuß, D.

As a baseline result, we provide evidence for significantly positive cumulative average abnormal CDS spread changes for both, European and North American acquirers suggesting that CDS investors perceive an increase in the acquiring firms’ credit risk exposures due to M&A announcements. Our baseline finding holds under several robustness checks, especially when controlling for the robustness of the empirical design. Moreover, results from a large variety of sensitivity analyses reveal a number of deal and firm characteristics that may explain why CDS investors from our sample expect an increase in the acquirers’ credit risk exposures due to forthcoming M&A transactions.

Our presented solution is an advancement of our system used in the previous edition of the task.We use a forward-backward convolutional recurrent neural network (FBCRNN) for tagging and pseudo labeling followed by tag-conditioned sound event detection (SED) models which are trained using strong pseudo labels provided by the FBCRNN. Our advancement over our earlier model is threefold. First, we introduce a strong label loss in the objective of the FBCRNN to take advantage of the strongly labeled synthetic data during training. Second, we perform multiple iterations of self-training for both the FBCRNN and tag-conditioned SED models. Third, while we used only tag-conditioned CNNs as our SED model in the previous edition we here explore sophisticated tag-conditioned SED model architectures, namely, bidirectional CRNNs and bidirectional convolutional transformer neural networks (CTNNs), and combine them. With metric and class specific tuning of median filter lengths for post-processing, our final SED model, consisting of 6 submodels (2 of each architecture), achieves on the public evaluation set poly-phonic sound event detection scores (PSDS) of 0.455 for scenario 1 and 0.684 for scenario as well as a collar-based F1-score of 0.596 outperforming the baselines and our model from the previous edition by far.

With state-of-the-art sound recognition being dominated by deep-learning-based approaches, there is a high demand for labeled training data. Despite the availability of large-scale  data sets such as Google's AudioSet, acquiring training data matching a certain application environment is still often a problem. In this paper we are concerned with human activity monitoring in a domestic environment using an ASN consisting of multiple nodes each providing multichannel signals. We propose a self-training based domain adaptation approach, which only requires unlabeled data from the target environment. Here, a sound recognition system trained on AudioSet, the teacher, generates pseudo labels for data from the target environment on which a student network is trained. The student can furthermore glean information about the spatial arrangement of sensors and sound sources to further improve classification performance. It is shown that  the student significantly improves recognition performance over the pre-trained teacher without relying on labeled data from the environment the system is deployed in.","lang":"eng"}],"publication":"Proceedings of the 29th European Signal Processing Conference (EUSIPCO)","type":"conference","language":[{"iso":"eng"}],"file_date_updated":"2022-01-13T08:19:35Z","ddc":["000"],"department":[{"_id":"54"}],"user_id":"34851","_id":"29306","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}]},{"main_file_link":[{"url":"https://meiner.de/media/attachment/file/m/e/meiner_telegramm_2021_04.pdf"}],"title":"»Wir hören Dich nicht, schalte bitte Dein Mikro an ! « Einige Gedanken zur digitalen Lehre in der Pandemie.","date_created":"2023-11-23T09:20:33Z","author":[{"first_name":"Sebastian","last_name":"Luft","id":"55271","full_name":"Luft, Sebastian"}],"date_updated":"2023-11-23T09:22:05Z","publisher":"Meiner Telegramm","page":"7","citation":{"ieee":"S.

In this paper, we argue that a novel conceptual framework is needed to overcome shortcomings of existing AI systems with little attention to processes of interaction and learning. Drawing from research in interaction and development, we first outline the novel conceptual framework that pushes the design of AI systems toward true interactivity with an emphasis on the role of the partner and social relevance. We propose that AI systems will be able to provide a meaningful and relevant explanation only if the process of explaining is extended to active contribution of both partners that brings about dynamics that is modulated by different levels of analysis. Accordingly, our conceptual framework comprises monitoring and scaffolding as key concepts and claims that the process of explaining is not only modulated by the interaction between explainee and explainer but is embedded into a larger social context in which conventionalized and routinized behaviors are established. We discuss our conceptual framework in relation to the established objectives of transparency and autonomy that are raised for the design of explainable AI systems currently.","lang":"eng"}],"date_created":"2021-09-14T20:52:57Z","title":"Explanation as a Social Practice: Toward a Conceptual Framework for the Social Design of AI Systems","issue":"3","quality_controlled":"1","year":"2021","department":[{"_id":"603"},{"_id":"749"},{"_id":"424"},{"_id":"67"},{"_id":"574"},{"_id":"184"},{"_id":"757"},{"_id":"54"},{"_id":"178"}],"user_id":"42933","_id":"24456","project":[{"grant_number":"438445824","_id":"109","name":"TRR 318: TRR 318 - Erklärbarkeit konstruieren"}],"file_date_updated":"2023-11-20T16:33:51Z","article_type":"original","type":"journal_article","status":"public","volume":13,"author":[{"first_name":"Katharina J.","last_name":"Rohlfing","full_name":"Rohlfing, Katharina J.","id":"50352"},{"first_name":"Philipp","last_name":"Cimiano","full_name":"Cimiano, Philipp"},{"full_name":"Scharlau, Ingrid","id":"451","last_name":"Scharlau","orcid":"0000-0003-2364-9489","first_name":"Ingrid"},{"last_name":"Matzner","id":"65695","full_name":"Matzner, Tobias","first_name":"Tobias"},{"first_name":"Heike M.","id":"27152","full_name":"Buhl, Heike M.","last_name":"Buhl"},{"last_name":"Buschmeier","full_name":"Buschmeier, Hendrik","first_name":"Hendrik"},{"last_name":"Esposito","full_name":"Esposito, Elena","first_name":"Elena"},{"full_name":"Grimminger, Angela","id":"57578","last_name":"Grimminger","first_name":"Angela"},{"first_name":"Barbara","last_name":"Hammer","full_name":"Hammer, Barbara"},{"id":"242","full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach","first_name":"Reinhold"},{"last_name":"Horwath","id":"68836","full_name":"Horwath, Ilona","first_name":"Ilona"},{"last_name":"Hüllermeier","id":"48129","full_name":"Hüllermeier, Eyke","first_name":"Eyke"},{"first_name":"Friederike","full_name":"Kern, Friederike","last_name":"Kern"},{"last_name":"Kopp","full_name":"Kopp, Stefan","first_name":"Stefan"},{"last_name":"Thommes","full_name":"Thommes, Kirsten","id":"72497","first_name":"Kirsten"},{"first_name":"Axel-Cyrille","full_name":"Ngonga Ngomo, Axel-Cyrille","id":"65716","last_name":"Ngonga Ngomo"},{"first_name":"Carsten","last_name":"Schulte","full_name":"Schulte, Carsten","id":"60311"},{"first_name":"Henning","id":"3900","full_name":"Wachsmuth, Henning","last_name":"Wachsmuth"},{"first_name":"Petra","last_name":"Wagner","full_name":"Wagner, Petra"},{"first_name":"Britta","last_name":"Wrede","full_name":"Wrede, Britta"}],"oa":"1","date_updated":"2023-12-05T10:15:02Z","doi":"10.1109/tcds.2020.3044366","publication_identifier":{"issn":["2379-8920","2379-8939"]},"has_accepted_license":"1","publication_status":"published","page":"717-728","intvolume":"        13","citation":{"chicago":"Rohlfing, Katharina J., Philipp Cimiano, Ingrid Scharlau, Tobias Matzner, Heike M.

In this paper we study evolutionary diversity optimization for the knapsack problem (KP). Our goal is to evolve a population of solutions that all have a profit of at least (1 - {$ϵ$}) {$\\cdot$} OPT, where OPT is the value of an optimal solution. Furthermore, they should differ in structure with respect to an entropy-based diversity measure. To this end we propose a simple ({$\\mu$} + 1)-EA with initial approximate solutions calculated by a well-known FPTAS for the KP. We investigate the effect of different standard mutation operators and introduce biased mutation and crossover which puts strong probability on flipping bits of low and/or high frequency within the population. An experimental study on different instances and settings shows that the proposed mutation operators in most cases perform slightly inferior in the long term, but show strong benefits if the number of function evaluations is severely limited."}],"author":[{"first_name":"Jakob","last_name":"Bossek","orcid":"0000-0002-4121-4668","full_name":"Bossek, Jakob","id":"102979"},{"last_name":"Neumann","full_name":"Neumann, Aneta","first_name":"Aneta"},{"first_name":"Frank","full_name":"Neumann, Frank","last_name":"Neumann"}],"date_updated":"2023-12-13T10:45:22Z","doi":"10.1145/3449639.3459364","publication_identifier":{"isbn":["978-1-4503-8350-9"]},"publication_status":"published","page":"556–564","citation":{"ieee":"J.

More formally, we analyse the expected hitting time of a target set OPT {$\\cup$} S where S is a set of non-optimal search points and OPT is the set of optima and compare it to the expected hitting time of OPT. We show that the answer to our question depends on the number and placement of search points in S. For all black-box algorithms and all fitness functions we show that, if additional optima are placed randomly, even an exponential number of optima has a negligible effect on the expected optimisation time. Considering Hamming balls around all global optima gives an easier target for some algorithms and functions and can shift the phase transition with respect to offspring population sizes in the (1,{$\\lambda$}) EA on One-Max.

For the traveling salesperson problem (TSP) a plethora of features have been suggested. Most of these features are, if at all, only normalized imprecisely raising the issue of feature values being strongly affected by the instance size. Such artifacts may have detrimental effects on algorithm selection models. We propose a normalization for two feature groups which stood out in multiple AS studies on the TSP: (a) features based on a minimum spanning tree (MST) and (b) a k-nearest neighbor graph (NNG) transformation of the input instance. To this end we theoretically derive minimum and maximum values for properties of MSTs and k-NNGs of Euclidean graphs. We analyze the differences in feature space between normalized versions of these features and their unnormalized counterparts. Our empirical investigations on various TSP benchmark sets point out that the feature scaling succeeds in eliminating the effect of the instance size. Eventually, a proof-of-concept AS-study shows promising results: models trained with normalized features tend to outperform those trained with the respective vanilla features.","lang":"eng"}],"user_id":"102979","department":[{"_id":"819"}],"_id":"48881","language":[{"iso":"eng"}],"extern":"1","keyword":["automated algorithm selection","graph theory","instance features","normalization","traveling salesperson problem (TSP)"]}]
