--- _id: '3586' abstract: - lang: eng text: Existing approaches and tools for the generation of approximate circuits often lack generality and are restricted to certain circuit types, approximation techniques, and quality assurance methods. Moreover, only few tools are publicly available. This hinders the development and evaluation of new techniques for approximating circuits and their comparison to previous approaches. In this paper, we first analyze and classify related approaches and then present CIRCA, our flexible framework for search-based approximate circuit generation. CIRCA is developed with a focus on modularity and extensibility. We present the architecture of CIRCA with its clear separation into stages and functional blocks, report on the current prototype, and show initial experiments. author: - first_name: Linus Matthias full_name: Witschen, Linus Matthias id: '49051' last_name: Witschen - first_name: Tobias full_name: Wiersema, Tobias id: '3118' last_name: Wiersema - first_name: Hassan full_name: Ghasemzadeh Mohammadi, Hassan id: '61186' last_name: Ghasemzadeh Mohammadi - first_name: Muhammad full_name: Awais, Muhammad id: '64665' last_name: Awais orcid: https://orcid.org/0000-0003-4148-2969 - first_name: Marco full_name: Platzner, Marco id: '398' last_name: Platzner citation: ama: 'Witschen LM, Wiersema T, Ghasemzadeh Mohammadi H, Awais M, Platzner M.

Compared to regular grids, they allow resembling the computational domain with a much higher accuracy, which in turn leads to more efficient computations.
There exists a wealth of supporting libraries and frameworks that aid programmers with the implementation of applications working on such grids, each built on top of existing parallelization technologies. However, many approaches require the programmer to introduce a different programming paradigm into their application or provide different variants of the code. SYCL is a new programming standard providing a remedy to this dilemma by building on standard C ++17 with its so-called single-source approach: Programmers write standard C ++ code and expose parallelism using C++17 keywords. The application is
then transformed into a concrete implementation by the SYCL implementation. By encapsulating the OpenCL ecosystem, different SYCL implementations enable not only the programming of CPUs but also of heterogeneous platforms such as GPUs or other devices. For the first time, this paper showcases a SYCL-
based solver for the nodal Discontinuous Galerkin method for Maxwell’s equations on unstructured meshes. We compare our solution to a previous C-based implementation with respect to programmability and performance on heterogeneous platforms.Proceedings of the 29th Annual IEEE International Conference on Application-Specific Systems, Architectures and Processors (ASAP). ; 2018:49-56. doi:10.1109/ASAP.2018.8445127' apa: 'Afzal, A., Schmitt, C., Alhaddad, S., Grynko, Y., Teich, J., Förstner, J., & Hannig, F.

For example, by recursively bisecting the original set of classes, so-called nested dichotomies define a set of binary classification problems that are organized in the structure of a binary tree. In contrast to the existing one-shot heuristics for constructing nested dichotomies and motivated by recent work on algorithm configuration, we propose a genetic algorithm for optimizing the structure of such dichotomies. A key component of this approach is the proposed genetic representation that facilitates the application of standard genetic operators, while still supporting the exchange of partial solutions under recombination. We evaluate the approach in an extensive experimental study, showing that it yields classifiers with superior generalization performance. author: - first_name: Marcel Dominik full_name: Wever, Marcel Dominik id: '33176' last_name: Wever orcid: ' https://orcid.org/0000-0001-9782-6818' - first_name: Felix full_name: Mohr, Felix last_name: Mohr - first_name: Eyke full_name: Hüllermeier, Eyke id: '48129' last_name: Hüllermeier citation: ama: 'Wever MD, Mohr F, Hüllermeier E.

An error bound for a semilinear heat equation is developed in such a way that the errors in the conflicting objectives can be estimated individually. The resulting algorithm constructs a library of locally valid reduced-order models online using a Greedy (worst-first) search. Using this approach, the number of evaluations of the full-order model can be reduced by a factor of more than 1000. author: - first_name: Dennis full_name: Beermann, Dennis last_name: Beermann - first_name: Michael full_name: Dellnitz, Michael last_name: Dellnitz - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Stefan full_name: Volkwein, Stefan last_name: Volkwein citation: ama: 'Beermann D, Dellnitz M, Peitz S, Volkwein S.

In this paper, we will propose an extension of DMD that exploits low-rank tensor decompositions of potentially high-dimensional data sets to compute the corresponding DMD modes and eigenvalues. The goal is to reduce the computational complexity and also the amount of memory required to store the data in order to mitigate the curse of dimensionality. The efficiency of these tensor-based methods will be illustrated with the aid of several different fluid dynamics problems such as the von Kármán vortex street and the simulation of two merging vortices. article_type: original author: - first_name: Stefan full_name: Klus, Stefan last_name: Klus - first_name: Patrick full_name: Gelß, Patrick last_name: Gelß - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Christof full_name: Schütte, Christof last_name: Schütte citation: ama: Klus S, Gelß P, Peitz S, Schütte C.

Following concepts from localized reduced bases methods, error estimators for the reduced cost functionals are utilized to construct a library of locally valid reduced order models. This way, a superset of the Pareto set can efficiently be computed while maintaining a prescribed error bound. In this article, this algorithm is applied to a problem with non‐smooth objective functionals. Using an academic example, we show that the extension to non‐smooth problems can be realized in a straightforward manner. We then discuss the implications on the numerical results. author: - first_name: Dennis full_name: Beermann, Dennis last_name: Beermann - first_name: Michael full_name: Dellnitz, Michael last_name: Dellnitz - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Stefan full_name: Volkwein, Stefan last_name: Volkwein citation: ama: 'Beermann D, Dellnitz M, Peitz S, Volkwein S.

Likewise, neural network based mask estimation for beamforming demonstrated very good noise suppression in the CHiME 3 and CHiME 4 challenges. Recently, it has been shown that this estimator can also be trained to perform dereverberation and denoising jointly. However, up to now a comparison of a neural beamformer and WPE is still missing, so is an investigation into a combination of the two. Therefore, we here provide an extensive evaluation of both and consequently propose variants to integrate deep neural network based beamforming with WPE. For these integrated variants we identify a consistent word error rate (WER) reduction on two distinct databases. In particular, our study shows that deep learning based beamforming benefits from a model-based dereverberation technique (i.e. WPE) and vice versa. Our key findings are: (a) Neural beamforming yields the lower WERs in comparison to WPE the more channels and noise are present. (b) Integration of WPE and a neural beamformer consistently outperforms all stand-alone systems.' author: - first_name: Lukas full_name: Drude, Lukas id: '11213' last_name: Drude - first_name: Christoph full_name: Boeddeker, Christoph id: '40767' last_name: Boeddeker - first_name: Jahn full_name: Heymann, Jahn id: '9168' last_name: Heymann - first_name: Keisuke full_name: Kinoshita, Keisuke last_name: Kinoshita - first_name: Marc full_name: Delcroix, Marc last_name: Delcroix - first_name: Tomohiro full_name: Nakatani, Tomohiro last_name: Nakatani - first_name: Reinhold full_name: Haeb-Umbach, Reinhold id: '242' last_name: Haeb-Umbach citation: ama: 'Drude L, Boeddeker C, Heymann J, et al.
