However, these benchmark functions have faced criticism for their limited resemblance to real-world problems. In response, recent research has focused on automatically generating new benchmark functions for areas where established test suites are inadequate. These approaches have limitations, such as the difficulty of generating new benchmark functions that exhibit exploratory landscape analysis (ELA) features beyond those of existing benchmarks.The objective of this work is to develop a method for generating benchmark functions for single-objective continuous optimization with user-specified structural properties. Specifically, we aim to demonstrate a proof of concept for a method that uses an ELA feature vector to specify these properties in advance. To achieve this, we begin by generating a random sample of decision space variables and objective values. We then adjust the objective values using CMA-ES until the corresponding features of our new problem match the predefined ELA features within a specified threshold. By iteratively transforming the landscape in this way, we ensure that the resulting function exhibits the desired properties. To create the final function, we use the resulting point cloud as training data for a simple neural network that produces a function exhibiting the target ELA features. We demonstrate the effectiveness of this approach by replicating the existing functions of the well-known BBOB suite and creating new functions with ELA feature values that are not present in BBOB."}],"user_id":"15504","publication":"Proceedings of the 17th ACM/SIGEVO Conference on Foundations of Genetic Algorithms","keyword":["Benchmarking","Instance Generator","Black-Box Continuous Optimization","Exploratory Landscape Analysis","Neural Networks"],"author":[{"first_name":"Raphael Patrick","full_name":"Prager, Raphael Patrick","last_name":"Prager"},{"last_name":"Dietrich","full_name":"Dietrich, Konstantin","first_name":"Konstantin"},{"last_name":"Schneider","first_name":"Lennart","full_name":"Schneider, Lennart"},{"first_name":"Lennart","full_name":"Schäpermeier, Lennart","last_name":"Schäpermeier"},{"last_name":"Bischl","first_name":"Bernd","full_name":"Bischl, Bernd"},{"first_name":"Pascal","full_name":"Kerschke, Pascal","last_name":"Kerschke"},{"last_name":"Trautmann","id":"100740","first_name":"Heike","orcid":"0000-0002-9788-8282","full_name":"Trautmann, Heike"},{"last_name":"Mersmann","first_name":"Olaf","full_name":"Mersmann, Olaf"}],"publisher":"Association for Computing Machinery","date_created":"2023-09-27T15:43:17Z","status":"public","date_updated":"2023-10-16T12:33:02Z","doi":"10.1145/3594805.3607136","series_title":"FOGA ’23","language":[{"iso":"eng"}],"place":"New York, NY, USA","title":"Neural Networks as Black-Box Benchmark Functions Optimized for Exploratory Landscape Features","department":[{"_id":"34"},{"_id":"819"}],"publication_identifier":{"isbn":["9798400702020"]}},{"date_updated":"2023-04-27T12:09:05Z","oa":"1","doi":"10.1109/AIRC56195.2022.9836982","language":[{"iso":"eng"}],"title":"Composed Physics- and Data-driven System Identification for Non-autonomous Systems in Control Engineering","department":[{"_id":"153"}],"_id":"26539","conference":{"end_date":"2021-12-10","location":"Cairo, Egypt","start_date":"2021-12-08","name":"3rd International Conference on Artificial Intelligence, Robotics and Control"},"main_file_link":[{"url":"https://arxiv.org/abs/2112.08148","open_access":"1"}],"year":"2022","citation":{"bibtex":"@inproceedings{Götte_Timmermann_2022, title={Composed Physics- and Data-driven System Identification for Non-autonomous Systems in Control Engineering}, DOI={10.1109/AIRC56195.2022.9836982}, booktitle={2022 3rd International Conference on Artificial Intelligence, Robotics and Control (AIRC)}, author={Götte, Ricarda-Samantha and Timmermann, Julia}, year={2022}, pages={67–76} }","mla":"Götte, Ricarda-Samantha, and Julia Timmermann. “Composed Physics- and Data-Driven System Identification for Non-Autonomous Systems in Control Engineering.” 2022 3rd International Conference on Artificial Intelligence, Robotics and Control (AIRC), 2022, pp. 67–76, doi:10.1109/AIRC56195.2022.9836982.","chicago":"Götte, Ricarda-Samantha, and Julia Timmermann. “Composed Physics- and Data-Driven System Identification for Non-Autonomous Systems in Control Engineering.” In 2022 3rd International Conference on Artificial Intelligence, Robotics and Control (AIRC), 67–76, 2022. https://doi.org/10.1109/AIRC56195.2022.9836982.","ama":"Götte R-S, Timmermann J.

In this contribution we extend existing methods towards the identification of non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN and a physics-inspired loss term (-L) to successfully identify the system's dynamics, while maintaining the consistency with physical laws. The proposed method is demonstrated on two real-world nonlinear systems and outperforms existing techniques regarding complexity and reliability.","lang":"eng"}],"user_id":"552","author":[{"first_name":"Ricarda-Samantha","full_name":"Götte, Ricarda-Samantha","last_name":"Götte","id":"43992"},{"full_name":"Timmermann, Julia","first_name":"Julia","id":"15402","last_name":"Timmermann"}],"quality_controlled":"1","keyword":["data-driven","physics-based","physics-informed","neural networks","system identification","hybrid modelling"],"publication":"2022 3rd International Conference on Artificial Intelligence, Robotics and Control (AIRC)","status":"public","date_created":"2021-10-19T14:47:17Z"},{"department":[{"_id":"153"}],"title":"Multi-Objective Physics-Guided Recurrent Neural Networks for Identifying Non-Autonomous Dynamical Systems","language":[{"iso":"eng"}],"doi":"https://doi.org/10.1016/j.ifacol.2022.07.282","date_updated":"2023-05-02T15:11:20Z","volume":55,"date_created":"2022-05-05T06:22:55Z","status":"public","publication":"14th IFAC Workshop on Adaptive and Learning Control Systems (ALCOS 2022)","keyword":["neural networks","physics-guided","data-driven","multi-objective optimization","system identification","machine learning","dynamical systems"],"quality_controlled":"1","author":[{"last_name":"Schön","first_name":"Oliver","full_name":"Schön, Oliver"},{"first_name":"Ricarda-Samantha","full_name":"Götte, Ricarda-Samantha","last_name":"Götte","id":"43992"},{"id":"15402","last_name":"Timmermann","full_name":"Timmermann, Julia","first_name":"Julia"}],"user_id":"43992","abstract":[{"text":"While trade-offs between modeling effort and model accuracy remain a major concern with system identification, resorting to data-driven methods often leads to a complete disregard for physical plausibility.

The miniaturized sensor platform called Sens-o-Spheres is used as an application of this locating method. The sensor platform is applied in bioreactors in order to obtain the environmental parameters, which makes a localization by magnetic fields necessary. Since the properties of magnetic fields in the localization area are very different from the wave characteristics, the principle of inductive localization is investigated in this publication and explained by using electrical equivalent circuit diagrams. Thereby, inductive localization uses the coupling or the mutual inductivities between coils, which is noticeable by an induced voltage. Therefore some properties and procedures are explained to extract the location of Sens-o-Spheres or other industrial sensor platforms from the couplings of the coils. One method calculates the location from an adapted ratio calculation and the other method uses neural networks and stochastic filters to obtain the results. In the end, these results are evaluated and compared.","lang":"eng"}],"status":"public","date_created":"2021-06-20T23:25:54Z","publisher":"IEEE","author":[{"last_name":"Lange","id":"38240","first_name":"Sven","full_name":"Lange, Sven"},{"first_name":"Dominik","full_name":"Schröder, Dominik","last_name":"Schröder"},{"full_name":"Hedayat, Christian","first_name":"Christian","last_name":"Hedayat"},{"first_name":"Harald","full_name":"Kuhn, Harald","last_name":"Kuhn"},{"last_name":"Hilleringmann","full_name":"Hilleringmann, Ulrich","first_name":"Ulrich"}],"publication":"22nd IEEE International Conference on Industrial Technology (ICIT)","keyword":["Location awareness","Coils","Couplings","Nonuniform electric fields","Magnetic separation","Neural networks","Training data"]},{"department":[{"_id":"59"},{"_id":"485"}],"publication_identifier":{"isbn":["9781728157306"]},"publication_status":"published","place":"Valencia, Spain ","title":"Detection of Defects on Irregular Structured Surfaces by Image Processing Methods for Feature Extraction","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:55:33Z","doi":"10.1109/icit46573.2021.9453646","publication":"22nd IEEE International Conference on Industrial Technology (ICIT)","keyword":["Image Processing","Defect Detection","wooden surfaces","Machine Learning","Neural Networks"],"author":[{"last_name":"Sander","full_name":"Sander, Tom","first_name":"Tom"},{"first_name":"Sven","full_name":"Lange, Sven","last_name":"Lange","id":"38240"},{"full_name":"Hilleringmann, Ulrich","first_name":"Ulrich","last_name":"Hilleringmann"},{"first_name":"Volker","full_name":"Geneis, Volker","last_name":"Geneis"},{"full_name":"Hedayat, Christian","first_name":"Christian","last_name":"Hedayat"},{"last_name":"Kuhn","first_name":"Harald","full_name":"Kuhn, Harald"},{"last_name":"Gockel","first_name":"Franz-Barthold","full_name":"Gockel, Franz-Barthold"}],"publisher":"IEEE","date_created":"2021-06-20T23:32:11Z","status":"public","abstract":[{"lang":"eng","text":"During the industrial processing of materials for the manufacture of new products, surface defects can quickly occur.

Such defects often manifest themselves by a deviation of the existing structure. The only restriction should be that only matt surfaces should be considered here. Therefore in this work, different classification and image processing algorithms are applied to surface data to identify possible surface damages.

On the classification side, however, deep neural networks, Convolutional Neural Networks (CNN), and autoencoders are used to make a decision. A distinction is also made between training using class labels and without. It turns out later that the salience metric are best performed by CNN.

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."}],"user_id":"48192","quality_controlled":"1","author":[{"first_name":"Clemens","orcid":"0000-0002-0455-0048","full_name":"Damke, Clemens","last_name":"Damke","id":"48192"},{"id":"48129","last_name":"Hüllermeier","full_name":"Hüllermeier, Eyke","first_name":"Eyke"}],"publisher":"Springer","publication":"Proceedings of The 24th International Conference on Discovery Science (DS 2021)","keyword":["Graph-structured data","Graph neural networks","Preference learning","Learning to rank"],"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":[{"full_name":"Soares, Carlos","first_name":"Carlos","last_name":"Soares"},{"last_name":"Torgo","first_name":"Luis","full_name":"Torgo, Luis"}],"publication_status":"published","publication_identifier":{"issn":["0302-9743","1611-3349"],"isbn":["9783030889418","9783030889425"]}},{"oa":"1","date_updated":"2022-01-06T06:54:17Z","language":[{"iso":"eng"}],"series_title":"Proceedings of Machine Learning Research","title":"A Novel Higher-order Weisfeiler-Lehman Graph Convolution","external_id":{"arxiv":["2007.00346"]},"place":"Bangkok, Thailand","publication_status":"published","editor":[{"last_name":"Jialin Pan","first_name":"Sinno","full_name":"Jialin Pan, Sinno"},{"first_name":"Masashi","full_name":"Sugiyama, Masashi","last_name":"Sugiyama"}],"department":[{"_id":"355"}],"conference":{"end_date":"2020-11-20","location":"Bangkok, Thailand","name":"Asian Conference on Machine Learning","start_date":"2020-11-18"},"intvolume":" 129","_id":"19953","page":"49-64","citation":{"ieee":"C.

We formally show that the resulting 2-WL-GNN architecture is more discriminative than existing GNN approaches.

On multiple common graph classification benchmarks, we demonstrate that the proposed model is competitive with state-of-the-art graph kernels and GNNs."}],"volume":129,"date_created":"2020-10-08T10:48:38Z","has_accepted_license":"1","status":"public","file_date_updated":"2020-10-08T11:24:29Z","keyword":["graph neural networks","Weisfeiler-Lehman test","cycle detection"],"publication":"Proceedings of the 12th Asian Conference on Machine Learning (ACML 2020)","publisher":"PMLR","quality_controlled":"1","author":[{"last_name":"Damke","id":"48192","first_name":"Clemens","full_name":"Damke, Clemens","orcid":"0000-0002-0455-0048"},{"id":"58747","last_name":"Melnikov","full_name":"Melnikov, Vitaly","first_name":"Vitaly"},{"last_name":"Hüllermeier","id":"48129","first_name":"Eyke","full_name":"Hüllermeier, Eyke"}],"file":[{"access_level":"open_access","date_created":"2020-10-08T10:54:48Z","file_name":"damke20.pdf","relation":"main_file","content_type":"application/pdf","date_updated":"2020-10-08T11:21:00Z","file_id":"19954","creator":"cdamke","file_size":771137},{"date_created":"2020-10-08T10:54:59Z","file_name":"damke20-supp.pdf","access_level":"open_access","creator":"cdamke","file_id":"19955","file_size":613163,"relation":"supplementary_material","date_updated":"2020-10-08T11:24:29Z","content_type":"application/pdf"}]},{"language":[{"iso":"eng"}],"year":"2019","citation":{"short":"C.
