[{"abstract":[{"lang":"eng","text":"DC-DC converters for on-board chargers (OBC) of electrical vehicles are usually galvanically isolated allowing modular single-phase PFC front-end solutions, but require transformers which are more bulky, costly and lossy than inductors of non-isolated DC-DCs. Furthermore, for vehicle-to-grid applications, bidirectional converters with transformers are generally more complex and have a higher count on semiconductor switches than transformerless solutions. However, when using non-isolated DC-DC converters within an OBC, the large common-mode (CM) capacitance comprising capacitive parasitics of the traction battery as well as explicit Y-capacitors connecting the high-voltage DC-system (HV-system) within specific HV-loads to ground has to be considered. For the PFC front-end stage, when supplied from the three-phase mains this means that generation of high-frequency and high-amplitude CM voltages, as it is common e.g. with the conventional six-switch full-bridge converter, has to be strictly avoided. For this reason, a modified topology is suggested leading to a different mode of operation and to a very low common-mode noise behaviour: The three-phase four-wire full-bridge PFC with split DC-link, whose midpoint is connected to the mains neutral provides very stable potentials at the DC-link rails and therefore it can be classified as Zero-CM-topology.For dedicated single-phase operation, as required for most OBC, an additional balancing leg may be added to the topology to reduce the required DC-link capacitance and allow non-electrolytic capacitors.The function of the bidirectional Zero-CM three-phase four-wire full-bridge PFC was verified by simulation and on an 11 kW-laboratory sample. The power factor is above 0.999 and an efficiency of 98 % is measured."}],"title":"Common-Mode-Free Bidirectional Three-Phase PFC-Rectifier for Non-Isolated EV Charger","user_id":"66","author":[{"first_name":"Benjamin","full_name":"Strothmann, Benjamin","last_name":"Strothmann","id":"22556"},{"full_name":"Schafmeister, Frank","first_name":"Frank","id":"71291","last_name":"Schafmeister"},{"first_name":"Joachim","full_name":"Böcker, Joachim","orcid":"0000-0002-8480-7295","last_name":"Böcker","id":"66"}],"publisher":"IEEE","department":[{"_id":"52"}],"publication":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","keyword":["Three-phase four-wire","OBC","Y2G","PFC","CM","EY charger","balancing circuit"],"publication_status":"published","status":"public","date_created":"2022-02-15T09:14:56Z","date_updated":"2022-02-21T19:25:17Z","_id":"29849","doi":"10.1109/apec42165.2021.9487462","year":"2021","citation":{"ieee":"B.

One solution for a power factor correction (PFC) rectifier that is capable to operate with a non-isolated DC-DC converter, is the three-phase four-wire full-bridge PFC, with split DC-link, whose midpoint is connected to the mains neutral. Therefore, it provides very stable potentials at the DC-link rails and accordingly can be classified as Zero-CM topology, which facilitates a common-mode-free operation. When to be operated at a single-phase supply, which is a common requirement for On-board chargers (OBCs) this topology results in the voltage-doubler PFC (V2-PFC) being characterised by a comparably large DC-link voltage ripple at mains frequency. If the DC-link capacitance shall be minimized, for instance to avoid lifetime-limited electrolytic capacitors, two more circuits in addition to the original V2-PFC are proposed for keeping the common-mode-free operation: A balancing circuit (BC), that balances the voltages over the split capacitors and a ripple port (RP), that buffers the 100 Hz power pulsation of the mains. For both circuits the available two bridge legs of the three-phase topology in single-phase operation may be utilized. A 3.7 kW laboratory sample verifies the functionality of the additional circuits in conjunction with the V2-PFC and achieves an efficiency of 95 %.","lang":"eng"}],"title":"Single-Phase Operation of Common-Mode-Free Bidirectional Three-Phase PFC-Rectifier for Non-Isolated EV Charger with Minimized DC-Link","user_id":"66","author":[{"last_name":"Strothmann","id":"22556","first_name":"Benjamin","full_name":"Strothmann, Benjamin"},{"first_name":"Gerrit","full_name":"Book, Gerrit","last_name":"Book"},{"first_name":"Frank","full_name":"Schafmeister, Frank","last_name":"Schafmeister","id":"71291"},{"id":"66","last_name":"Böcker","full_name":"Böcker, Joachim","orcid":"0000-0002-8480-7295","first_name":"Joachim"}],"publication":"PCIM Europe digital days 2021; International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management","department":[{"_id":"52"}],"publication_status":"published","status":"public","date_created":"2022-02-15T10:25:25Z"},{"abstract":[{"text":"LLC resonant converters typically employ power\r\nMOSFETs in their inverter stage. The generally weak reverse\r\nrecovery behaviour of the intrinsic body diodes of those\r\nMOSFETs causes significant turn-on losses when being forced\r\nto hard commutations. Continuous operation in this way will\r\nlead to self-destruction of the transistors. Consequently,\r\nzero-voltage switching (ZVS) is essential in a MOSFET-based\r\ninverter stage. To ensure ZVS, the LLC converter is operated in\r\nthe inductive region. On the contrary, IGBTs show dominant\r\nturn-off losses and are therefore conventionally not applied in\r\nLLC converters typically requiring high switching frequencies\r\nto achieve low output voltages. However, if the LLC converter\r\nis intentionally designed for capacitive operation, zero-current\r\nswitching (ZCS) is enabled and thus robust and cost-efficient\r\nIGBTs can be applied in the inverter stage. The aim of this work\r\nis to investigate the use IGBTs in the inverter of an LLC\r\nconverter. The theory behind the capacitive operated LLC is\r\nderived using a switched simulation model and compared with\r\nthe fundamental harmonic approximation (FHA). The results\r\nprove FHA to be useless for practical converter design. Instead,\r\na stress value analysis based on switched model simulations is\r\nproposed to the design a capacitive operated LLC utilizing ZCS.\r\nA 2 kW prototype for on-board EV applications was built to\r\nverify the theory and design approach. The prototype confirms\r\nthe derived theory and thus the deployment of IGBTs in the\r\ninverter stage of LLC resonant converters. Synchronous\r\nrectification turns out to require a specific control solution, but\r\nif given the resulting efficiency in the most critical operation\r\npoint exceeds the value of a MOSFET-based (inductive\r\noperated) LLC-design of an identical application. Therefore,\r\nthis concept should be further developed.","lang":"eng"}],"title":"LLC Converter in Capacitive Operation Utilizing ZCS for IGBTs – Theory, Concept and Verification of a 2 kW DC-DC Converter for EVs","ddc":["620"],"user_id":"60223","author":[{"full_name":"Urbaneck, Daniel","first_name":"Daniel","id":"60223","last_name":"Urbaneck"},{"first_name":"Philipp","full_name":"Rehlaender, Philipp","last_name":"Rehlaender","id":"69469"},{"orcid":"0000-0002-8480-7295","full_name":"Böcker, Joachim","first_name":"Joachim","id":"66","last_name":"Böcker"},{"full_name":"Schafmeister, Frank","first_name":"Frank","id":"71291","last_name":"Schafmeister"}],"publication":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","department":[{"_id":"52"}],"publication_status":"published","status":"public","has_accepted_license":"1","date_created":"2022-02-18T09:36:01Z","_id":"29871","date_updated":"2022-02-23T16:12:38Z","conference":{"end_date":"2021-06-17","location":"Arizona","start_date":"2021-06-14","name":"Applied Power Electronics Conference (APEC)"},"main_file_link":[{"url":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9487109"}],"citation":{"chicago":"Urbaneck, Daniel, Philipp Rehlaender, Joachim Böcker, and Frank Schafmeister. “LLC Converter in Capacitive Operation Utilizing ZCS for IGBTs – Theory, Concept and Verification of a 2 KW DC-DC Converter for EVs.” In 2021 IEEE Applied Power Electronics Conference and Exposition (APEC), 2021.","apa":"Urbaneck, D., Rehlaender, P., Böcker, J., & Schafmeister, F.

Recently, it was shown that TPhCs based on weak topology with a dislocation inherit this robustness and further host topologically protected lower-dimensional localized modes. However, TPhCs with weak topology at optical frequencies have not been demonstrated so far. Here, we use scattering-type scanning near-field optical microscopy to verify mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with nontrivial Zak phase and an edge dislocation. We show that because of the weak topology, differently extended dislocation centers induce similarly strong light localization. The experimental results are supported by full-field simulations. Along with the underlying fundamental physics, our results lay a foundation for the application of TPhCs based on weak topology in active topological nanophotonics, and nonlinear and quantum optic integrated devices because of their strong and robust light localization.","lang":"eng"}],"article_type":"original","date_created":"2021-12-02T19:40:56Z","status":"public","has_accepted_license":"1","volume":7,"file":[{"file_id":"30197","creator":"zentgraf","file_size":2609760,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2022-03-03T07:24:44Z","file_name":"2021_ScienceAdv_TopologicalMode_Manuscript_Arxiv.pdf","date_created":"2022-03-03T07:24:44Z","access_level":"closed"}],"file_date_updated":"2022-03-03T07:24:44Z","publication":"Science Advances","quality_controlled":"1","author":[{"last_name":"Lu","full_name":"Lu, Jinlong","first_name":"Jinlong"},{"last_name":"Wirth","first_name":"Konstantin G.","full_name":"Wirth, Konstantin G."},{"last_name":"Gao","first_name":"Wenlong","full_name":"Gao, Wenlong"},{"last_name":"Heßler","first_name":"Andreas","full_name":"Heßler, Andreas"},{"last_name":"Sain","first_name":"Basudeb","full_name":"Sain, Basudeb"},{"full_name":"Taubner, Thomas","first_name":"Thomas","last_name":"Taubner"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","id":"30525","last_name":"Zentgraf"}],"issue":"49","article_number":"eabl3903","_id":"28255","intvolume":" 7","year":"2021","citation":{"short":"J.

Since conventional joining processes reach their limits in the connection of these components, new methods and technologies are necessary in order to be able to react versatilely to varying process and disturbance variables. For fundamental investigations of new possibilities in joining technology, numerical investigations are helpful to identify process parameters. To generate valid results, robust and efficient material models are developed which are adapted to the requirements of versatile joining technologies, for instance to the high plastic strains associated with self-piercing riveting. To describe the inherent strain-induced plastic orthotropy of sheet metal an anisotropic Hill-plasticity model is formulated. Tensile tests for different sheet orientations are conducted both experimentally and numerically to adjust the anisotropic material parameters by inverse parameter identification for aluminium EN AW-6014 and steel HCT590X.

This method offers potential for the direct manufacturing of CFRT–metal structures via embedded pin structures. Despite the previous studies, a deeper understanding of the process of energy input and whether fibers work as energy directors and consequently can, in combination with chosen processing parameters, influence the consolidation quality of the CFRTs, is still unknown. Consequently, the aim of this work is to establish a deeper process understanding of the ultrasonic direct impregnation of fiber-reinforced thermoplastics with an emphasis on the fiber’s function as energy directors. Based on the generated insights, a better assessment of the feasibility of direct, hybrid part manufacturing is possible. The produced samples were primarily evaluated by optical and mechanical test methods. It is demonstrated that with higher welding time and amplitude, a better consolidation quality can be achieved and that independent of the process parameters chosen in this study, no significant fiber breakage occurs. This is interpreted as a sign of a gentle impregnation process. Furthermore, based on the examination of single roving and 5-layer set-ups, it is shown that the glass fibers function as energy directors and can influence the transformation of sonic energy into thermal energy. In comparison to industrially available CFRT material, the mechanical properties are weaker, but materials and processes offer potential for significant improvement. Based on these findings, proposals for a direct impregnation and joining process are made.","lang":"eng"}],"language":[{"iso":"eng"}],"citation":{"apa":"Popp, J., Wolf, M., Mattner, T., & Drummer, D.

Previous considerations primarily focused on the mechanical properties. The multitude of possible combinations of requirements, materials, and component- and joining-geometry makes an empirical determination of these joining properties for the clinching process impossible. Based on the established and empirical procedure, there is currently no model that takes into account all questions of joinability—i.e., the materials (suitability for joining), design (security of joining), and production (joining possibility)—that allows a calculation of the properties that can be achieved. It is therefore necessary to describe the physical properties of the joint as a function of the three binding mechanisms—form closure, force closure, and material closure—in relation to the application. This approach illustrates the relationships along the causal chain “joint requirement-binding mechanism-joining parameters” and improves the adaptability of the mechanical joining technology. Geometrical properties of clinch connections of the combination of aluminum and steel are compared in a metallographic cross-section. The mechanical stress state of the rotationally symmetrical clinch points is qualified with a torsion test and by measuring the electrical resistance in the base material, in the clinch joint, and during the production cycle (after clinching, before precipitation hardening and after precipitation hardening)."}],"volume":5,"project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"138","name":"TRR 285 – A04: TRR 285 - Subproject A04"}],"date_created":"2022-03-28T12:22:53Z","status":"public","publication":"Journal of Manufacturing and Materials Processing","author":[{"full_name":"Kalich, J.","first_name":"J.","last_name":"Kalich"},{"first_name":"U.","full_name":"Füssel, U.","last_name":"Füssel"}],"doi":"10.3390/jmmp5040105","date_updated":"2022-03-29T12:41:44Z","_id":"30643","intvolume":" 5","page":"105","year":"2021","citation":{"ieee":"J.

In this work we extend the earlier proposed non-deterministic computational homogenization framework to plastic materials, thereby increasing the model versatility and overall realism. We apply novel soft periodic boundary conditions and estimate their effect in case of non-periodic material microstructures. We study macroscopic plasticity signatures like the macroscopic von-Mises stress and make useful conclusions for further constitutive modeling.

In this context, mechanical joining processes offer an environmentally friendly and flexible alternative to established joining methods, especially in the field of lightweight design. For example, cold-formed cylindrical pin structures show high potentials in joining multi-material-systems without auxiliary elements. The pin structures are joined either by pressing them directly into the joining partner or by caulking with a pre-punched part. However, to evaluate the strength of the joint and to ensure the joining reliability for versatile processes, such as changing joining partners or batch variations, engineering designers currently have only limited design principles available compared to thermal joining processes. Consequently, the design of an optimal pin joint requires cost- and time-intensive experimental investigations and adjustments to design or process parameters. As a solution, data-driven methods offer procedures for structuring data and identifying dependencies between varying process parameters and resulting pin structure characteristics. Motivated by this, the paper presents an approach for the data-driven analysis of cold-formed pin structures and offers a deeper understanding of how versatile processes affect the pin characteristics. Therefore, the application of an intelligent design of experiment in combination with several machine learning methods enable the setup of a best-fitting meta-model. Resulting, the determination of a mathematical model provides the opportunity to accurately estimate the pin height considering only relevant geometrical and process parameters with a prediction quality of 95 %.","lang":"eng"}],"title":"Data-driven analysis of cold-formed pin structure characteristics in the context of versatile joining processes","user_id":"68518","author":[{"last_name":"Römisch","first_name":"D.","full_name":"Römisch, D."},{"last_name":"Zirngibl","full_name":"Zirngibl, C.","first_name":"C."},{"last_name":"Schleich","first_name":"B.","full_name":"Schleich, B."},{"first_name":"S.","full_name":"Wartzack, S.","last_name":"Wartzack"},{"first_name":"M.","full_name":"Merklein, M.","last_name":"Merklein"}],"publication":"IOP Conference Series: Materials Science and Engineering","volume":1157,"status":"public","project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B05: TRR 285 - Subproject B05","_id":"144"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C01: TRR 285 - Subproject C01","_id":"145"}],"date_created":"2022-03-28T12:48:01Z"},{"abstract":[{"text":"In clinching, the combinations of requirements, materials, component dimensions and tools influence the resulting joint geometry and the resulting bonding mechanisms. These in turn affect the property profile of the joint. For example, it is possible to use different tools to flexibly adapt clinching points to the respective required load regime. Clinching points dimensioned in this way can be geometrically similar, but have different mechanical stress states, which leads to different properties in terms of load-bearing behavior. Within the scope of this work, the clinching process with different tools in optimal and compromise design and its effect on the force and form-closure component, is investigated in a torsion test of the clinched connection. Clinched steel sheets with two thicknesses and joining directions are analyzed. Virtual experiments are carried out using finite element analyses (FEA) of the joining process and are followed by a springback simulation. Subsequently, the surface pressure between the two joining partners in the clinching points is calculated on the basis of the results from the FEA and the transmittable moment of the connection, as an indicator for the force-closure component, is determined.

The resulting fiber rearrangement is assessed using transmitted light microscopy, confocal laser scanning microscopy as well as micro-computer-tomography. It could be shown that for all assessed pin variants a similar distinct fiber displacement can be seen and that the pin diameter has a significant effect on the resulting fiber orientation with smaller pin diameters being advantageous because of gentle fiber displacement and reduced undulation. The tip geometry has only minor effect on the fiber orientation. Especially in the X/Y plane no systematic influence of the tip geometry on the fiber displacement could be observed.

However, XCT is a relatively young technology in the field of dimensional metrology and thus faces several challenges. The achievement of a high measurement resolution, which is re-quired to detect small geometrical features, depends on a variety of influencing factors. In this arti-cle, the interface structural resolution (ISR) as one of the key challenges will be investigated. The two-sphere standard called the hourglass standard allows the determination of the structural resolu-tion by evaluation of the surrounding area of an ideal point contact of two spheres after the CT re-construction in form of a neck-shaped transition. Close to the contact point of the two spheres two opposing surfaces exist. Their distances from each other increase as the distance from the contact point of the two spheres increase. The determination of the distances between the spheres’ surface allows a statement about the ISR. A new developed specimen or standard with a variable gap size consisting of calibrated parallel gauge blocks allows statements about the ISR, too. Because of the higher number of probing points of the gauge block standard the results of the determined ISR are more stable compared to the hourglass standard. This paper compares the results of the computed tomography measurements for the designed interface structural resolution standard with those of the hourglass standard.

Even worse, the problem may not be noticed, and an alleged CW still be produced. In this paper, we therefore address the problem as a ”testification” task, by which we mean a combination of testing and identification: The online identification of the CW is combined with the statistical testing of the CW assumption. Thus, instead of returning a supposed CW at some point, the learner has the possibility to stop sampling and refuse an answer in case it feels confident that the CW assumption is violated. Analyzing the testification problem formally, we derive lower bounds on the expected sample complexity of any online algorithm solving it. Moreover, a concrete algorithm is proposed, which achieves the optimal sample complexity up to logarithmic terms.","lang":"eng"}],"user_id":"38261","title":"Testification of Condorcet Winners in dueling bandits","publication":"Proceedings of the Thirty-Seventh Conference on Uncertainty in Artificial Intelligence","author":[{"first_name":"Björn","full_name":"Haddenhorst, Björn","last_name":"Haddenhorst"},{"last_name":"Bengs","full_name":"Bengs, Viktor","first_name":"Viktor"},{"last_name":"Brandt","first_name":"Jasmin","full_name":"Brandt, Jasmin"},{"last_name":"Hüllermeier","first_name":"Eyke","full_name":"Hüllermeier, Eyke"}],"publisher":"PMLR","date_created":"2022-03-30T06:14:16Z","status":"public","volume":161,"editor":[{"last_name":"de Campos","first_name":"Cassio","full_name":"de Campos, Cassio"},{"last_name":"Maathuis","first_name":"Marloes H.","full_name":"Maathuis, Marloes H."}],"date_updated":"2022-03-30T06:15:49Z","_id":"30725","intvolume":" 161","series_title":"Proceedings of Machine Learning Research","language":[{"iso":"eng"}],"page":"1195–1205","citation":{"bibtex":"@inproceedings{Haddenhorst_Bengs_Brandt_Hüllermeier_2021, series={Proceedings of Machine Learning Research}, title={Testification of Condorcet Winners in dueling bandits}, volume={161}, booktitle={Proceedings of the Thirty-Seventh Conference on Uncertainty in Artificial Intelligence}, publisher={PMLR}, author={Haddenhorst, Björn and Bengs, Viktor and Brandt, Jasmin and Hüllermeier, Eyke}, editor={de Campos, Cassio and Maathuis, Marloes H.}, year={2021}, pages={1195–1205}, collection={Proceedings of Machine Learning Research} }","mla":"Haddenhorst, Björn, et al. “Testification of Condorcet Winners in Dueling Bandits.” Proceedings of the Thirty-Seventh Conference on Uncertainty in Artificial Intelligence, edited by Cassio de Campos and Marloes H.

A clinch point’s quality is usually assessed using ex-situ destructive testing methods. These, however, are unable to detect phenomena immediately during the joining process. For instance, elastic deformations reverse and cracks close after unloading. In-situ methods such as the force-displacement evaluation are used to control a clinching process, though deviations in the clinch point geometry cannot be derived with this method. To overcome these limitations, the clinching process can be investigated using in-situ computed tomography (in-situ CT). However, a clinching tool made of steel would cause strong artefacts and a high attenuation in the CT measurement, reducing the significance of this method. Additionally, when joining parts of the same material, the sheet-sheet interface is hardly detectable. This work aims at identifying, firstly, tool materials that allow artefact-reduced CT measurements during clinching, and, secondly, radiopaque materials that can be applied between the joining parts to enhance the detectability of the sheet-sheet interface. Therefore, both CT-suitable tool materials and radiopaque materials are selected and experimentally investigated. In the clinching process, two aluminium sheets with radiopaque material in between are clinched in a single-step (rotationally symmetric joint without cut section). It is shown that e.g. silicon nitride is suited as tool material and a tin layer is suitable to enhance the detectability of the sheet-sheet interface.

However, these methods do not yield the detection of phenomena occurring during loading such as elastic deformations and cracks that close after unloading. Alternatively, in situ computed tomography (in situ CT) can be used to investigate the loading process of clinch points. In this paper, a method for in situ CT analysis of a single-lap shear test with clinched metal sheets is presented at the example of a clinched joint with two 2 mm thick aluminum sheets. Furthermore, the potential of this method to validate numerical simulations is shown. Since the sheets’ surfaces are locally in contact with each other, the interface between both aluminum sheets and therefore the exact contour of the joining partners is difficult to identify in CT analyses. To compensate for this, the application of copper varnish between the sheets is investigated. The best in situ CT results are achieved with both sheets treated. It showed that with this treatment, in situ CT is suitable to properly observe the three-dimensional deformation behavior and to identify the failure modes."}],"title":"In Situ Computed Tomography—Analysis of a Single-Lap Shear Test with Clinch Points","user_id":"68518","page":"1859","year":"2021","type":"journal_article","citation":{"short":"D.

One trend is the increased use of multi-material systems, which are characterised by the use of different materials such as high-strength steels or aluminium alloys. In addition to the varying mechanical properties of the components, an increased number of variants accompanied by different geometries is leading to increasing challenges on body construction. For the assembly and connection of the individual components, conventional joining methods reach their limitations. Therefore, new joining methods are necessary, which feature properties of versatility and can adapt to process and disturbance variables. One way of achieving tailored joints is to use a tumbling self-piercing riveting process. For the design of the process route, numerical investigations are necessary for which a characterisation of the friction properties is necessary. This paper therefore investigates the contact and friction conditions that occur in a tumbling self-piercing riveting process. The individual contacts between the process components are identified and based on this, suitable processes for the characterisation of the friction factors - and coefficients are selected and performed.","lang":"eng"}],"status":"public","project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"}],"date_created":"2022-03-29T10:35:19Z","volume":883,"author":[{"first_name":"S.","full_name":"Wituschek, S.","last_name":"Wituschek"},{"full_name":"Lechner, M.","first_name":"M.","last_name":"Lechner"}],"publication":"Key Engineering Materials","doi":"10.4028/www.scientific.net/kem.883.27","_id":"30719","date_updated":"2022-03-29T15:54:33Z","intvolume":" 883","language":[{"iso":"eng"}],"type":"journal_article","year":"2021","citation":{"ama":"Wituschek S, Lechner M.

Motivated by the broad applicability of GNNs, we propose the family of so-called RankGNNs, a combination of neural Learning to Rank (LtR) methods and GNNs. RankGNNs are trained with a set of pair-wise preferences between graphs, suggesting that one of them is preferred over the other. One practical application of this problem is drug screening, where an expert wants to find the most promising molecules in a large collection of drug candidates. We empirically demonstrate that our proposed pair-wise RankGNN approach either significantly outperforms or at least matches the ranking performance of the naive point-wise baseline approach, in which the LtR problem is solved via GNN-based graph regression.","lang":"eng"}],"user_id":"48192","publisher":"Springer","author":[{"first_name":"Clemens","full_name":"Damke, Clemens","orcid":"0000-0002-0455-0048","last_name":"Damke","id":"48192"},{"full_name":"Hüllermeier, Eyke","first_name":"Eyke","id":"48129","last_name":"Hüllermeier"}],"quality_controlled":"1","keyword":["Graph-structured data","Graph neural networks","Preference learning","Learning to rank"],"publication":"Proceedings of The 24th International Conference on Discovery Science (DS 2021)","volume":12986,"status":"public","date_created":"2021-11-11T14:15:18Z","date_updated":"2022-04-11T22:08:12Z","doi":"10.1007/978-3-030-88942-5","series_title":"Lecture Notes in Computer Science","language":[{"iso":"eng"}],"external_id":{"arxiv":["2104.08869"]},"title":"Ranking Structured Objects with Graph Neural Networks","department":[{"_id":"355"}],"editor":[{"last_name":"Soares","full_name":"Soares, Carlos","first_name":"Carlos"},{"full_name":"Torgo, Luis","first_name":"Luis","last_name":"Torgo"}],"publication_status":"published","publication_identifier":{"issn":["0302-9743","1611-3349"],"isbn":["9783030889418","9783030889425"]}},{"year":"2021","citation":{"apa":"Tornede, T., Tornede, A., Hanselle, J.

Over the last decade, AutoML has developed into an\r\nindependent research field with hundreds of contributions. While AutoML offers\r\nmany prospects, it is also known to be quite resource-intensive, which is one\r\nof its major points of criticism. The primary cause for a high resource\r\nconsumption is that many approaches rely on the (costly) evaluation of many\r\nmachine learning pipelines while searching for good candidates. This problem is\r\namplified in the context of research on AutoML methods, due to large scale\r\nexperiments conducted with many datasets and approaches, each of them being run\r\nwith several repetitions to rule out random effects. In the spirit of recent\r\nwork on Green AI, this paper is written in an attempt to raise the awareness of\r\nAutoML researchers for the problem and to elaborate on possible remedies. To\r\nthis end, we identify four categories of actions the community may take towards\r\nmore sustainable research on AutoML, i.e. Green AutoML: design of AutoML\r\nsystems, benchmarking, transparency and research incentives."}],"external_id":{"arxiv":["2111.05850"]}},{"article_number":"117357","doi":"10.1016/j.ces.2021.117357","_id":"30864","date_updated":"2022-04-12T11:41:50Z","intvolume":" 251","type":"journal_article","year":"2021","citation":{"apa":"Schulz, A., Wecker, C., Inguva, V., Lopatin, A.
