We recently proposed a way to support the model-based Generalized Eigenvalue beamforming operation with a powerful neural network for spectral mask estimation. The enhancement system has a number of desirable properties. In particular, neither assumptions need to be made about the nature of the acoustic transfer function (e.g., being anechonic), nor does the array configuration need to be known. While the system has been originally developed to enhance speech in noisy environments, we show in this article that it is also effective in suppressing reverberation, thus leading to a generic trainable multi-channel speech enhancement system for robust speech processing. To support this claim, we consider two distinct datasets: The CHiME 3 challenge, which features challenging real-world noise distortions, and the Reverb challenge, which focuses on distortions caused by reverberation. We evaluate the system both with respect to a speech enhancement and a recognition task. For the first task we propose a new way to cope with the distortions introduced by the Generalized Eigenvalue beamformer by renormalizing the target energy for each frequency bin, and measure its effectiveness in terms of the PESQ score. For the latter we feed the enhanced signal to a strong DNN back-end and achieve state-of-the-art ASR results on both datasets. We further experiment with different network architectures for spectral mask estimation: One small feed-forward network with only one hidden layer, one Convolutional Neural Network and one bi-directional Long Short-Term Memory network, showing that even a small network is capable of delivering significant performance improvements."}],"publication":"Computer Speech and Language","citation":{"mla":"Heymann, Jahn, et al. “A Generic Neural Acoustic Beamforming Architecture for Robust Multi-Channel Speech Processing.” <i>Computer Speech and Language</i>, 2017.","bibtex":"@article{Heymann_Drude_Haeb-Umbach_2017, title={A Generic Neural Acoustic Beamforming Architecture for Robust Multi-Channel Speech Processing}, journal={Computer Speech and Language}, author={Heymann, Jahn and Drude, Lukas and Haeb-Umbach, Reinhold}, year={2017} }","ama":"Heymann J, Drude L, Haeb-Umbach R.

Techniques, such as interviewing by requirements engineers, are typically applied to identify the user’s needs. We want to partially automate even this first step of requirements elicitation by methods of evolutionary computation. The idea is to enable users to specify their desired software by listing examples of behavioral descriptions. Users initially specify two lists of operation sequences, one with desired behaviors and one with forbidden behaviors. Then, we search for the appropriate formal software specification in the form of a deterministic finite automaton. We solve this problem known as grammatical inference with an active coevolutionary approach following Bongard and Lipson [2]. The coevolutionary process alternates between two phases: (A) additional training data is actively proposed by an evolutionary process and the user is interactively asked to label it; (B) appropriate automata are then evolved to solve this extended grammatical inference problem. Our approach leverages multi-objective evolution in both phases and outperforms the state-of-the-art technique [2] for input alphabet sizes of three and more, which are relevant to our problem domain of requirements specification."}],"_id":"120","page":"1327--1334","ddc":["000"],"user_id":"477","status":"public","has_accepted_license":"1","citation":{"mla":"Wever, Marcel Dominik, et al. “Active Coevolutionary Learning of Requirements Specifications from Examples.” <i>Proceedings of the Genetic and Evolutionary Computation Conference (GECCO)</i>, 2017, pp. 1327--1334, doi:<a href=\"https://doi.org/10.1145/3071178.3071258\">10.1145/3071178.3071258</a>.","bibtex":"@inproceedings{Wever_van Rooijen_Hamann_2017, title={Active Coevolutionary Learning of Requirements Specifications from Examples}, DOI={<a href=\"https://doi.org/10.1145/3071178.3071258\">10.1145/3071178.3071258</a>}, booktitle={Proceedings of the Genetic and Evolutionary Computation Conference (GECCO)}, author={Wever, Marcel Dominik and van Rooijen, Lorijn and Hamann, Heiko}, year={2017}, pages={1327--1334} }","ama":"Wever MD, van Rooijen L, Hamann H.

However, researchers have only recently started to investigate ad copies in the context of paid search, and have not yet explored the potential of information cues to enhance customers’ search process. In this paper we analyze the impact of an information cue on user behavior in ad copies. Contrary to prevalent advice, results suggest that reducing the number of words in an ad is not always beneficial. Users act quite differently (and unexpectedly) in response to an information cue depending on their search phrases. In turn, practitioners could leverage the observed moderating effect of an information cue to enhance paid search success. Furthermore, having detected deviating user behavior in terms of clicks and conversions, we provide first indicative evidence of a self-selection mechanism at play when paid search users respond to differently phrased ad copies.","lang":"eng"}]},{"has_accepted_license":"1","date_updated":"2022-01-06T06:51:18Z","author":[{"full_name":"Schlangenotto, Darius","last_name":"Schlangenotto","first_name":"Darius"},{"full_name":"Kundisch, Dennis","first_name":"Dennis","last_name":"Kundisch","id":"21117"},{"id":"14368","full_name":"Gutt, Dominik","first_name":"Dominik","last_name":"Gutt"}],"conference":{"location":"Seoul, South Korea","name":"38th International Conference on Information Systems (ICIS)"},"title":"Achieving More by Paying Less?

This paper presents a field experiment using differences-in-differences analysis to investigate whether the targeting of a less prominent ad position can be beneficial for bricks-and-mortar retailers. Results indicate that paid search advertising budgets could be allocated more efficiently by targeting less prominent ad positions, thus allowing bricks-and-mortar retailers with a limited marketing budget to increase the reach of their marketing campaign, attract more consumers to their website and achieve an overall increase in conversions. Furthermore, the pay-per-click billing mechanism allows advertisers to increase their marketing reach at no additional cost. Consequently, bricks-and-mortar retailers should consider targeting less prominent ad positions to reduce advertising costs while simultaneously enhancing advertising benefits."}],"citation":{"apa":"Schlangenotto, D., Kundisch, D., &#38; Gutt, D.

Architectural knowledge of the existing ecosystems is implicit and fragmented among online documentation. In protection of intellectual property, existing documentation hardly reveals influential business strategies that affect the ecosystem structure. Thus, other platform providers can hardly learn from the existing ecosystems in order to systematically make reasonable design decisions with respect to their business strategies to create their own ecosystems. In this paper, we identify a variability model for architectural design decisions of a store-oriented software ecosystem product line from an enterprise perspective, comprising business, application, and infrastructure views. We derive the variability model from fragmentary material of existing ecosystems and a rigorous literature review using a research method based on the design science paradigm. To show its validity, we describe real-world ecosystems from diverse domains using the variability model. This knowledge helps platform providers to develop customized ecosystems or to recreate existing designs in a systematic way. This, in turn, contributes to an increase in designer and developer productivity."}]},{"abstract":[{"text":"Searching for other participants is one of the most important operations in a distributed system.We are interested in topologies in which it is possible to route a packet in a fixed number of hops until it arrives at its destination.Given a constant $d$, this paper introduces a new self-stabilizing protocol for the $q$-ary $d$-dimensional de Bruijn graph ($q = \\sqrt[d]{n}$) that is able to route any search request in at most $d$ hops w.h.p., while significantly lowering the node degree compared to the clique: We require nodes to have a degree of $\\mathcal O(\\sqrt[d]{n})$, which is asymptotically optimal for a fixed diameter $d$.The protocol keeps the expected amount of edge redirections per node in $\\mathcal O(\\sqrt[d]{n})$, when the number of nodes in the system increases by factor $2^d$.The number of messages that are periodically sent out by nodes is constant.","lang":"eng"}],"publication":"Proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS)","department":[{"_id":"79"}],"type":"conference","date_created":"2017-10-17T12:41:16Z","file":[{"content_type":"application/pdf","success":1,"file_id":"5214","date_updated":"2018-10-31T13:30:13Z","relation":"main_file","access_level":"closed","file_size":311204,"file_name":"Feldmann-Scheideler2017_Chapter_ASelf-stabilizingGeneralDeBrui.pdf","date_created":"2018-10-31T13:30:13Z","creator":"mfeldma2"}],"intvolume":"     10616","publication_status":"published","date_updated":"2022-01-06T06:51:19Z","publication_identifier":{"isbn":["978-3-319-69083-4"]},"author":[{"first_name":"Michael","last_name":"Feldmann","full_name":"Feldmann, Michael","id":"23538"},{"id":"20792","first_name":"Christian","last_name":"Scheideler","full_name":"Scheideler, Christian"}],"year":"2017","title":"A Self-Stabilizing General De Bruijn Graph","doi":"10.1007/978-3-319-69084-1_17","series_title":"Lecture Notes in Computer Science","language":[{"iso":"eng"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A1","_id":"5"},{"_id":"2","name":"SFB 901 - Project Area A"}],"citation":{"mla":"Feldmann, Michael, and Christian Scheideler. “A Self-Stabilizing General De Bruijn Graph.” <i>Proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS)</i>, vol. 10616, Springer, Cham, 2017, pp. 250–64, doi:<a href=\"https://doi.org/10.1007/978-3-319-69084-1_17\">10.1007/978-3-319-69084-1_17</a>.","ama":"Feldmann M, Scheideler C.
