This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. \r\nOne solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services.\r\n\r\nIn this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure.","lang":"eng"}],"main_file_link":[{"url":"http://ieeexplore.ieee.org/document/7956044/"}],"language":[{"iso":"eng"}],"doi":"10.1109/EWSDN.2016.9","title":"Understand Your Chains: Towards Performance Profile-Based Network Service Management","year":"2016","author":[{"full_name":"Peuster, Manuel","first_name":"Manuel","last_name":"Peuster","id":"13271"},{"id":"126","full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger"}],"publication_status":"published","date_updated":"2022-01-06T07:03:33Z"},{"language":[{"iso":"eng"}],"doi":"10.1109/NETSOFT.2016.7502432","author":[{"id":"13271","full_name":"Peuster, Manuel","last_name":"Peuster","first_name":"Manuel"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"title":"E-State: Distributed state management in elastic network function deployments","year":"2016","date_updated":"2022-01-06T07:03:35Z","publication_status":"published","date_created":"2017-11-27T10:22:25Z","file":[{"date_created":"2018-06-25T13:10:43Z","creator":"peuster","file_id":"3354","content_type":"application/pdf","relation":"main_file","date_updated":"2018-06-25T13:16:47Z","file_name":"main_ris.pdf","file_size":696049,"access_level":"open_access"}],"department":[{"_id":"75"}],"type":"conference","publication":"IEEE NetSoft Conference and Workshops, NetSoft 2016, Seoul, South Korea, June 6-10, 2016","abstract":[{"lang":"eng","text":"Elastic deployments of virtualized network functions~(VNF) can automatically scale the amount of used resources in relation to their workload. This is often done by starting new VNF instances or stopping old ones. A problem of these scale operations is that most network functions are stateful and their internal state is not automatically migrated when traffic is redistributed in the deployment. As a result, mechanisms are needed to exchange or migrate internal network function state between VNF instances.\r\n\r\nThis paper presents a state management framework that creates a logically distributed state store on top of elastically deployed virtual network functions. We also introduce a novel programming model that provides both a local and a global view of the state to each VNF instance.

This allows to improve service performance by optimizing its placement in the network. But prototyping and testing of these complex distributed software systems becomes extremely challenging. The reason is that not only the network service as such has to be tested but also its integration with management and orchestration systems. Existing solutions, like simulators, basic network emulators, or local cloud testbeds, do not support all aspects of these tasks.\r\n\r\nTo this end, we introduce MeDICINE, a novel NFV prototyping platform that is able to execute production-ready network functions, provided as software containers, in an emulated multi-PoP environment. These network functions can be controlled by any third-party management and orchestration system that connects to our platform through standard interfaces. Based on this, a developer can use our platform to prototype and test complex network services in a realistic environment running on his laptop.\r\n"}],"publication":"IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)","department":[{"_id":"75"}],"type":"conference","date_created":"2017-11-27T10:22:25Z","file":[{"creator":"peuster","date_created":"2018-06-25T13:06:47Z","access_level":"open_access","file_size":848438,"file_name":"main_ris.pdf","date_updated":"2018-06-25T13:17:34Z","relation":"main_file","content_type":"application/pdf","file_id":"3349"}],"date_updated":"2022-01-06T07:03:36Z","publication_status":"published","author":[{"last_name":"Peuster","first_name":"Manuel","full_name":"Peuster, Manuel","id":"13271"},{"full_name":"Karl, Holger","first_name":"Holger","last_name":"Karl","id":"126"},{"full_name":"van Rossem, Steven","last_name":"van Rossem","first_name":"Steven"}],"year":"2016","title":"MeDICINE: Rapid Prototyping of Production-Ready Network Services in Multi-PoP Environments","doi":"10.1109/NFV-SDN.2016.7919490","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/pdf/1606.05995.pdf"}]},{"ddc":["000"],"user_id":"61579","language":[{"iso":"eng"}],"_id":"5595","date_updated":"2022-01-06T07:02:05Z","has_accepted_license":"1","year":"2016","title":"Factors Affecting the Scientific Impact of Literature Reviews: A Scientometric Study","status":"public","author":[{"full_name":"Wagner, Gerit","first_name":"Gerit","last_name":"Wagner"},{"last_name":"Prester","first_name":"Julian","full_name":"Prester, Julian"},{"full_name":"Roche, Maria","last_name":"Roche","first_name":"Maria"},{"last_name":"Benlian","first_name":"Alexander","full_name":"Benlian, Alexander"},{"id":"72850","full_name":"Schryen, Guido","first_name":"Guido","last_name":"Schryen"}],"type":"conference","oa":"1","department":[{"_id":"277"}],"file":[{"content_type":"application/pdf","file_id":"6030","file_size":725409,"access_level":"open_access","file_name":"ICIS2016 - Factors Affecting the Scientific Impact of Literature Reviews.pdf","date_updated":"2018-12-13T15:08:15Z","relation":"main_file","date_created":"2018-12-07T11:38:41Z","creator":"hsiemes"}],"date_created":"2018-11-14T11:34:31Z","extern":"1","publication":"International Conference on Information Systems","file_date_updated":"2018-12-13T15:08:15Z","citation":{"ama":"Wagner G, Prester J, Roche M, Benlian A, Schryen G.

At the same time, techniques for distorting and obscuring the text, which are used to maintain the level of security, make text-based CAPTCHAs diffcult to solve for humans, and thereby further degrade usability. The need for developing alternative types of CAPTCHAs which improve both, the current security and usability levels, has been emphasized by several researchers.

For extended flexibility, we go beyond seeing services as a fixed chain of functions. We present a YANG model for describing the service structure in deployment requests in a flexible way that enables changing the order of functions in case the order of traversing them does not affect the functionality of the service. Upon receiving such requests, the network orchestration system can choose the optimal composition of service components that gives the best results for placement of services in the network. This introduces new complexities to the placement problem by greatly increasing the number of possible ways a service can be composed. In this paper, we describe a heuristic solution that selects a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different resource requirements of the services. Our evaluations show that the selected combinations consist of representative samples of possible structures and requirements and therefore, can result in optimal or close-to-optimal placement results.","lang":"eng"}]},{"related_material":{"link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2016/ChHa16_Poster.pdf","relation":"supplementary_material","description":"Poster"}]},"abstract":[{"text":"In this contribution we investigate a priori signal-to-noise ratio (SNR) estimation, a crucial component of a single-channel speech enhancement system based on spectral subtraction. The majority of the state-of-the art a priori SNR estimators work in the power spectral domain, which is, however, not confirmed to be the optimal domain for the estimation. Motivated by the generalized spectral subtraction rule, we show how the estimation of the a priori SNR can be formulated in the so called generalized SNR domain. This formulation allows to generalize the widely used decision directed (DD) approach. An experimental investigation with different noise types reveals the superiority of the generalized DD approach over the conventional DD approach in terms of both the mean opinion score - listening quality objective measure and the output global SNR in the medium to high input SNR regime, while we show that the power spectrum is the optimal domain for low SNR. We further develop a parameterization which adjusts the domain of estimation automatically according to the estimated input global SNR.

While the parameters of the noise model are calculated from the noise power spectral density estimates, the speechWMM parameters are estimated from the noisy signal by applying a causal Expectation-Maximization algorithm.

This paper presents a critical assessment whether the novel tool set of deep neural networks (DNNs) should be extended to complex-valued arithmetic. Indeed, with DNNs making inroads in speech enhancement tasks, the use of complex-valued input data, specifically the short-time Fourier transform coefficients, is an obvious consideration. In particular when it comes to performing tasks that heavily rely on phase information, such as acoustic beamforming, complex-valued algorithms are omnipresent. In this contribution we recapitulate backpropagation in CVNNs, develop complex-valued network elements, such as the split-rectified non-linearity, and compare real- and complex-valued networks on a beamforming task. We find that CVNNs hardly provide a performance gain and conclude that the effort of developing the complex-valued counterparts of the building blocks of modern deep or recurrent neural networks can hardly be justified."}],"related_material":{"link":[{"description":"Poster","url":"https://groups.uni-paderborn.de/nt/pubs/2016/interspeech_2016_drude_slides.pdf","relation":"supplementary_material"}]},"main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2016/interspeech_2016_drude_paper.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"_id":"11756","user_id":"44006","year":"2016","status":"public","title":"On the appropriateness of complex-valued neural networks for speech enhancement","author":[{"full_name":"Drude, Lukas","first_name":"Lukas","last_name":"Drude","id":"11213"},{"full_name":"Raj, Bhiksha","last_name":"Raj","first_name":"Bhiksha"},{"full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242"}],"date_updated":"2022-01-06T06:51:08Z"},{"main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2016/itgspeech2016_08_Glarner.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"_id":"11771","user_id":"44006","title":"Factor Graph Decoding for Speech Presence Probability Estimation","year":"2016","status":"public","author":[{"full_name":"Glarner, Thomas","first_name":"Thomas","last_name":"Glarner","id":"14169"},{"last_name":"Mahdi Momenzadeh","first_name":"Mohammad","full_name":"Mahdi Momenzadeh, Mohammad"},{"full_name":"Drude, Lukas","first_name":"Lukas","last_name":"Drude","id":"11213"},{"first_name":"Reinhold","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold","id":"242"}],"date_updated":"2022-01-06T06:51:08Z","date_created":"2019-07-12T05:27:56Z","type":"conference","oa":"1","department":[{"_id":"54"}],"publication":"12.

We are going to develop a model for the DoA estimation error in a reverberant scenario and show the existence of a bias, that is a consequence of the linear arrangement and limited field of view (FoV) bias: First, the limited FoV leading to a clipping of the measurements, and, second, the angular distribution of the signal energy of the reflections being non-uniform. Since both issues are a consequence of the linear arrangement of the sensors, the bias arises largely independent of the kind of DoA estimator. The experimental evaluation demonstrates the existence of the bias for a selected number of DoA estimation methods and proves that the prediction from the developed theoretical model matches the simulation results."}],"_id":"11829","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2016/JacobHaeb_ITG2016.pdf"}],"user_id":"44006","author":[{"full_name":"Jacob, Florian","first_name":"Florian","last_name":"Jacob"},{"id":"242","last_name":"Haeb-Umbach","first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold"}],"title":"On the Bias of Direction of Arrival Estimation Using Linear Microphone Arrays","year":"2016","status":"public","date_updated":"2022-01-06T06:51:10Z"},{"date_updated":"2022-01-06T06:51:11Z","status":"public","year":"2016","title":"Wide Residual BLSTM Network with Discriminative Speaker Adaptation for Robust Speech Recognition","author":[{"id":"9168","first_name":"Jahn","last_name":"Heymann","full_name":"Heymann, Jahn"},{"full_name":"Drude, Lukas","last_name":"Drude","first_name":"Lukas","id":"11213"},{"id":"242","first_name":"Reinhold","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold"}],"user_id":"44006","main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2016/chime4_upbonly_paper.pdf","open_access":"1"}],"_id":"11834","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"We present a system for the 4th CHiME challenge which significantly increases the performance for all three tracks with respect to the provided baseline system.

The back-end consists of a 22 layer deep Wide Residual Network and two extra BLSTM layers. Working on a whole utterance instead of frames allows us to refine Batch-Normalization. We also train our own BLSTM-based language model. Adding a discriminative speaker adaptation leads to further gains. The final system achieves a word error rate on the six channel real test data of 3.48%. For the two channel track we achieve 5.96% and for the one channel track 9.34%. This is the best reported performance on the challenge achieved by a single system, i.e., a configuration, which does not combine multiple systems. At the same time, our system is independent of the microphone configuration. We can thus use the same components for all three tracks."}],"related_material":{"link":[{"relation":"supplementary_material","url":"https://groups.uni-paderborn.de/nt/pubs/2016/chime4_upbonly_poster.pdf","description":"Poster"}]},"publication":"Computer Speech and Language","citation":{"ama":"Heymann J, Drude L, Haeb-Umbach R.

In the 2ch and 6ch tracks the final system output is obtained by a Confusion Network Combination (CNC) of multiple systems. The Acoustic Model (AM) is a deep neural network based on Bidirectional Long Short-Term Memory (BLSTM) units. The systems differ by front ends and training sets used for the acoustic training. The model for the 1ch track is trained without any preprocessing. For each front end we trained and evaluated individual acoustic models. We compare the ASR performance of different beamforming approaches: a conventional superdirective beamformer [1] and an MVDR beamformer as in [2], where the steering vector is estimated based on [3]. Furthermore we evaluated a BLSTM supported Generalized Eigenvalue beamformer using NN-GEV [4]. The back end is implemented using RWTH?s open-source toolkits RASR [5], RETURNN [6] and rwthlm [7]. We rescore lattices with a Long Short-Term Memory (LSTM) based language model. The overall best results are obtained by a system combination that includes the lattices from the system of UPB?s submission [8].

We exploit the assumption of a hierarchical structure of speech, namely the formation of spoken words as a sequence of phonemes. We employ the Nested Hierarchical Pitman-Yor Language Model, which allows an a priori unknown and possibly unlimited number of words. We assume the n-gram probabilities of words, the m-gram probabilities of phoneme sequences in words and the phoneme sequences of the words themselves as latent variables to be learned. We evaluate the algorithm on a cross language task using an existing speech recognizer trained on English speech to decode speech in the Xitsonga language supplied for the 2015 ZeroSpeech challenge. We apply the learning algorithm on the resulting phoneme graphs and achieve the highest token precision and F score compared to present systems.","lang":"eng"}],"related_material":{"link":[{"description":"Presentation","relation":"supplementary_material","url":"https://groups.uni-paderborn.de/nt/pubs/2016/WaHa16_Talk.pdf"}]},"_id":"11920","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2016/WaHa16.pdf"}],"user_id":"44006","author":[{"first_name":"Oliver","last_name":"Walter","full_name":"Walter, Oliver"},{"last_name":"Haeb-Umbach","first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold","id":"242"}],"title":"Unsupervised Word Discovery from Speech using Bayesian Hierarchical Models","year":"2016","status":"public","date_updated":"2022-01-06T06:51:12Z"},{"publication":"„Ei, dem alten Herrn zoll’ ich Achtung gern“","type":"book_chapter","department":[{"_id":"233"},{"_id":"43"}],"file":[{"title":"Projektmanagement in digitalen Forschungsprojekten.","content_type":"application/pdf","file_id":"12936","date_updated":"2019-08-16T13:05:57Z","relation":"main_file","file_size":253199,"access_level":"open_access","file_name":"2016_Röwenstrunk_Projektmanagement.pdf","date_created":"2019-08-16T12:56:16Z","creator":"danruebe"}],"date_created":"2019-08-16T12:54:22Z","date_updated":"2022-01-06T06:51:27Z","year":"2016","title":"Projektmanagement in digitalen Forschungsprojekten","author":[{"last_name":"Komprecht","first_name":"Anna Maria","full_name":"Komprecht, Anna Maria"},{"id":"439","full_name":"Röwenstrunk, Daniel","orcid":"https://orcid.org/0000-0001-6271-2095","last_name":"Röwenstrunk","first_name":"Daniel"}],"doi":"10.25366/2018.33","language":[{"iso":"eng"}],"file_date_updated":"2019-08-16T13:05:57Z","citation":{"ama":"Komprecht AM, Röwenstrunk D.
