As in previous editions of the Challenge, we use forward-backward convolutional recurrent neural networks (FBCRNNs) [1, 2] for weakly labeled and semi-supervised sound event detection (SED) and eventually generate strong pseudo labels for weakly labeled and unlabeled data. Then, (tag-conditioned) bidirectional CRNNs (Bi-CRNNs) [1, 2] are trained in a strongly supervised manner as our final SED models. In each of the training stages we use multiple iterations of self-training. Compared to previous editions, we improved our system performance by 1) some tweaks regarding data augmentation, pseudo labeling and inference 2) using weakly labeled AudioSet data [3] for pretraining larger networks and 3) augmenting the DESED data [4] with strongly labeled AudioSet data [5] for finetuning of the networks.

As a second example, a printed circuit board is considered and the calculated far-field is compared to a fullwave simulation. In both cases, the calculations for different field integral equations are under comparison, and the results indicate that the presented method performs very well with a combined field integral equation, for the specified problem, when only magnetic Huygens box data is given.","lang":"eng"}],"publication":"2022 Smart Systems Integration (SSI)","keyword":["Near-Field Scanning","Huygens Box","Boundary Element Method","Method of Moments","tet_topic_hf","tet_enas"],"language":[{"iso":"eng"}],"year":"2022","title":"Far-field Calculation from magnetic Huygens Box Data using the Boundary Element Method","publisher":"IEEE","date_created":"2022-10-04T11:31:43Z"},{"ddc":["000"],"language":[{"iso":"eng"}],"external_id":{"arxiv":["2111.07578"]},"abstract":[{"lang":"eng","text":"Impressive progress in neural network-based single-channel speech source\r\nseparation has been made in recent years.

We find three principal configurations of hole polarons: (i) self-trapped holes localized at displaced regular oxygen atoms and (ii) two other configurations bound to a lithium vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated oxygen atom below the defect. The latter is the most stable and is in excellent quantitative agreement with measured g factors from electron paramagnetic resonance. Due to the absence of mid-gap states, none of these hole polarons can explain the broad optical absorption centered between 2.5 and 2.8 eV that is observed in transient absorption spectroscopy, but such states appear if a free electron polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon experiments. The coexistence of hole and exciton polarons, which are simultaneously created in optical excitations, thus satisfactorily explains the reported experimental data."}],"file":[{"title":"A density-functional theory study of hole and defect-bound exciton polarons in lithium niobate","description":"Creative Commons Attribution 4.0 International Public License (CC BY 4.0)","file_size":1762554,"file_id":"45570","file_name":"crystals-12-01586-v2.pdf","access_level":"open_access","date_updated":"2023-06-12T00:22:51Z","creator":"schindlm","date_created":"2023-06-11T23:59:27Z","relation":"main_file","content_type":"application/pdf"}],"date_updated":"2025-09-18T13:28:05Z","oa":"1","author":[{"full_name":"Schmidt, Falko","id":"35251","last_name":"Schmidt","orcid":"0000-0002-5071-5528","first_name":"Falko"},{"full_name":"Kozub, Agnieszka L.","id":"77566","last_name":"Kozub","orcid":"0000-0001-6584-0201","first_name":"Agnieszka L."},{"full_name":"Gerstmann, Uwe","id":"171","orcid":"0000-0002-4476-223X","last_name":"Gerstmann","first_name":"Uwe"},{"first_name":"Wolf Gero","id":"468","full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076"},{"first_name":"Arno","full_name":"Schindlmayr, Arno","id":"458","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X"}],"volume":12,"doi":"10.3390/cryst12111586","publication_status":"published","has_accepted_license":"1","publication_identifier":{"eissn":["2073-4352"]},"citation":{"apa":"Schmidt, F., Kozub, A.

In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients."}],"publication":"New Trends in Lithium Niobate: From Bulk to Nanocrystals","title":"Electron polarons in lithium niobate: Charge localization, lattice deformation, and optical response","publisher":"MDPI","date_created":"2022-03-13T15:28:47Z","year":"2022","quality_controlled":"1","_id":"30288","project":[{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"_id":"69","name":"TRR 142 - B4: TRR 142 - Subproject B4"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"TRR 142 - A11: TRR 142 - Subproject A11","_id":"166"},{"_id":"168","name":"TRR 142 - B07: TRR 142 - Subproject B07"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"}],"department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"35"},{"_id":"790"}],"user_id":"16199","editor":[{"last_name":"Corradi","full_name":"Corradi, Gábor","first_name":"Gábor"},{"first_name":"László","full_name":"Kovács, László","last_name":"Kovács"}],"status":"public","type":"book_chapter","doi":"10.3390/books978-3-0365-3339-1","date_updated":"2025-12-05T14:00:04Z","author":[{"id":"35251","full_name":"Schmidt, Falko","orcid":"0000-0002-5071-5528","last_name":"Schmidt","first_name":"Falko"},{"first_name":"Agnieszka L.","last_name":"Kozub","orcid":"https://orcid.org/0000-0001-6584-0201","full_name":"Kozub, Agnieszka L.","id":"77566"},{"first_name":"Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann","full_name":"Gerstmann, Uwe","id":"171"},{"last_name":"Schmidt","orcid":"0000-0002-2717-5076","id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero"},{"full_name":"Schindlmayr, Arno","id":"458","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X","first_name":"Arno"}],"place":"Basel","page":"231-248","citation":{"mla":"Schmidt, Falko, et al. “Electron Polarons in Lithium Niobate: Charge Localization, Lattice Deformation, and Optical Response.” <i>New Trends in Lithium Niobate: From Bulk to Nanocrystals</i>, edited by Gábor Corradi and László Kovács, MDPI, 2022, pp. 231–48, doi:<a href=\"https://doi.org/10.3390/books978-3-0365-3339-1\">10.3390/books978-3-0365-3339-1</a>.","short":"F.

At the same time, two-colour nonlinear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically developed and investigated an integrated multimode two-colour SU(1,1) interferometer operating in a supersensitive mode. By ensuring the proper design of the integrated platform, we suppressed the dispersion, thereby significantly increasing the visibility of the interference pattern. The use of a continuous wave pump laser provided the symmetry between the spectral shapes of the signal and idler photons concerning half the pump frequency, despite different photon colours. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to 3×104 photons are generated.</jats:p>"}],"user_id":"16199","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"429"},{"_id":"230"},{"_id":"9"},{"_id":"27"}],"project":[{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"name":"TRR 142 - C2: TRR 142 - Subproject C2","_id":"72"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"40371","language":[{"iso":"eng"}],"article_number":"552","keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"]},{"publication_status":"published","year":"2021","citation":{"apa":"Meyer, M.

Generally speaking, AutoML approaches comprise two major components: a search space model and an optimizer for traversing the space. Recent approaches have shown impressive results in the realm of supervised learning, most notably (single-label) classification (SLC). Moreover, first attempts at extending these approaches towards multi-label classification (MLC) have been made. While the space of candidate pipelines is already huge in SLC, the complexity of the search space is raised to an even higher power in MLC. One may wonder, therefore, whether and to what extent optimizers established for SLC can scale to this increased complexity, and how they compare to each other. This paper makes the following contributions: First, we survey existing approaches to AutoML for MLC. Second, we augment these approaches with optimizers not previously tried for MLC. Third, we propose a benchmarking framework that supports a fair and systematic comparison. Fourth, we conduct an extensive experimental study, evaluating the methods on a suite of MLC problems. We find a grammar-based best-first search to compare favorably to other optimizers.","lang":"eng"}],"publication":"IEEE Transactions on Pattern Analysis and Machine Intelligence","type":"journal_article"},{"has_accepted_license":"1","citation":{"apa":"Haeb-Umbach, R., Heymann, J., Drude, L., Watanabe, S., Delcroix, M., &#38; Nakatani, T.

Meanwhile it has entered the consumer market with digital home assistants with a spoken language interface being its most prominent application. Speech recorded at a distance is affected by various acoustic distortions and, consequently, quite different processing pipelines have emerged compared to ASR for close-talk speech. A signal enhancement front-end for dereverberation, source separation and acoustic beamforming is employed to clean up the speech, and the back-end ASR engine is robustified by multi-condition training and adaptation. We will also describe the so-called end-to-end approach to ASR, which is a new promising architecture that has recently been extended to the far-field scenario. This tutorial article gives an account of the algorithms used to enable accurate speech recognition from a distance, and it will be seen that, although deep learning has a significant share in the technological breakthroughs, a clever combination with traditional signal processing can lead to surprisingly effective solutions."}],"language":[{"iso":"eng"}],"ddc":["000"]},{"citation":{"ama":"Mohr F, Wever MD, Tornede A, Hüllermeier E.

Increasing the surface area of the CN condensates in the presence of ZnCl2 salt melts enhances the amount of CO2 adsorbed while preserving the high selectivity values and C1N1 structure.
