In general, service-oriented computing emphasizes the construction of large software systems out of existing services, where services are small and self-contained pieces of software that adhere to a specified interface. Several implementations of the same interface are considered as several instances of the same service. Thereby, customers are interested in buying the best service implementation for their service composition wrt. to metrics, such as costs, energy, memory consumption, or execution time. One way to ensure the service quality is to employ certificates, which can come in different kinds: Technical certificates proving correctness can be automatically constructed by the service provider and again be automatically checked by the user. Digital certificates allow proof of the integrity of a product. Other certificates might be rolled out if service providers follow a good software construction principle, which is checked in annual audits. Whereas all of these certificates are handled differently in service markets, what they have in common is that they influence the buying decisions of customers.

In AutoML the selection, composition and parametrization of machine learning algorithms is automated and tailored to a specific problem, resulting in a machine learning pipeline. Current approaches reduce the AutoML problem to optimization of hyperparameters. Based on recursive task networks, in this paper we present one approach from the field of automated planning and one evolutionary optimization approach. Instead of simply parametrizing a given pipeline, this allows for structure optimization of machine learning pipelines, as well. We evaluate the two approaches in an extensive evaluation, finding both approaches to have their strengths in different areas. Moreover, the two approaches outperform the state-of-the-art tool Auto-WEKA in many settings.}}, author = {{Wever, Marcel Dominik and Mohr, Felix and Hüllermeier, Eyke}}, booktitle = {{27th Workshop Computational Intelligence}}, location = {{Dortmund}}, title = {{{Automatic Machine Learning: Hierachical Planning Versus Evolutionary Optimization}}}, year = {{2017}}, } @inproceedings{15397, author = {{Melnikov, Vitaly and Hüllermeier, Eyke}}, booktitle = {{in Proceedings 27th Workshop Computational Intelligence, Dortmund Germany}}, editor = {{Hoffmann, F. and Hüllermeier, Eyke and Mikut, R.}}, pages = {{1--12}}, publisher = {{KIT Scientific Publishing}}, title = {{{Optimizing the structure of nested dichotomies.

In order to optimally satisfy service requesters and service providers, adequate techniques for automatic service matching are needed. However, a requester’s requirements may be vague and the information available about a provided service may be incomplete. As a consequence, fuzziness is induced into the matching procedure. The contribution of this paper is the development of a systematic matching procedure that leverages concepts and techniques from fuzzy logic and possibility theory based on our formal distinction between different sources and types of fuzziness in the context of service matching. In contrast to existing methods, our approach is able to deal with imprecision and incompleteness in service specifications and to inform users about the extent of induced fuzziness in order to improve the user’s decision-making. We demonstrate our approach on the example of specifications for service reputation based on ratings given by previous users. Our evaluation based on real service ratings shows the utility and applicability of our approach.}}, author = {{Platenius, Marie Christin and Shaker, Ammar and Becker, Matthias and Hüllermeier, Eyke and Schäfer, Wilhelm}}, journal = {{IEEE Transactions on Software Engineering (TSE), presented at ICSE 2017}}, number = {{8}}, pages = {{739--759}}, publisher = {{IEEE}}, title = {{{Imprecise Matching of Requirements Specifications for Software Services using Fuzzy Logic}}}, doi = {{10.1109/TSE.2016.2632115}}, year = {{2016}}, } @inproceedings{184, abstract = {{In this paper, we propose a framework for a class of learning problems that we refer to as “learning to aggregate”. Roughly, learning-to-aggregate problems are supervised machine learning problems, in which instances are represented in the form of a composition of a (variable) number on constituents; such compositions are associated with an evaluation, score, or label, which is the target of the prediction task, and which can presumably be modeled in the form of a suitable aggregation of the properties of its constituents. Our learning-to-aggregate framework establishes a close connection between machine learning and a branch of mathematics devoted to the systematic study of aggregation functions. We specifically focus on a class of functions called uninorms, which combine conjunctive and disjunctive modes of aggregation. Experimental results for a corresponding model are presented for a review data set, for which the aggregation problem consists of combining different reviewer opinions about a paper into an overall decision of acceptance or rejection.}}, author = {{Melnikov, Vitaly and Hüllermeier, Eyke}}, booktitle = {{Proceedings of the Joint European Conference on Machine Learning and Knowledge Discovery in Databases (ECML/PKDD 2016)}}, pages = {{756--771}}, title = {{{Learning to Aggregate Using Uninorms}}}, doi = {{10.1007/978-3-319-46227-1_47}}, year = {{2016}}, } @misc{10785, author = {{Fürnkranz, J. and Hüllermeier, Eyke}}, booktitle = {{Encyclopedia of Machine Learning and Data Mining}}, editor = {{Sammut, C. and Webb, G.I.}}, publisher = {{Springer}}, title = {{{Preference Learning}}}, year = {{2016}}, } @inproceedings{15400, author = {{Labreuche, C. and Hüllermeier, Eyke and Vojtas, P. and Fallah Tehrani, A.}}, booktitle = {{in Proceedings DA2PL 2016 EURO Mini Conference From Multiple Criteria Decision Aid to Preference Learning, Paderborn Germany}}, editor = {{Busa-Fekete, R. and Hüllermeier, Eyke and Mousseau, V. and Pfannschmidt, Karlson}}, title = {{{On the identifiability of models in multi-criteria preference learning}}}, year = {{2016}}, } @inproceedings{15401, author = {{Schäfer, D. and Hüllermeier, Eyke}}, booktitle = {{in Proceedings DA2PL`2016 Euro Mini Conference From Multiple Criteria Decision Aid to Preference Learning, Paderborn, Germany}}, editor = {{Busa-Fekete, R. and Hüllermeier, Eyke and Mousseau, V. and Pfannschmidt, Karlson}}, title = {{{Preference -based reinforcement learning using dyad ranking}}}, year = {{2016}}, } @inproceedings{15402, author = {{Couso, Ines and Ahmadi Fahandar, Mohsen and Hüllermeier, Eyke}}, booktitle = {{in Proceedings DA2PL 2016 EURO Mini Conference From Multiple Criteria Decision Aid to Preference Learning, Paderborn Germany}}, editor = {{Busa-Fekete, R. and Hüllermeier, Eyke and Mousseau, V. and Pfannschmidt, Karlson}}, title = {{{Statistical Inference for Incomplete Ranking Data: A Comparison of two likelihood-based estimators}}}, year = {{2016}}, } @inproceedings{15403, author = {{Lu, S. and Hüllermeier, Eyke}}, booktitle = {{in Proceedings 26th Workshop Computational Intelligence, Dortmund Germany}}, editor = {{Hüllermeier, Eyke and Hoffmann, F. and Mikut, R.}}, pages = {{1--8}}, publisher = {{KIT Scientific Publishing}}, title = {{{Support vector classification on noisy data using fuzzy superset losses}}}, year = {{2016}}, } @inproceedings{15404, author = {{Schäfer, D. and Hüllermeier, Eyke}}, booktitle = {{in Workshop LWDA "Lernen, Wissen, Daten, Analysen" Potsdam, Germany}}, title = {{{Plackett-Luce networks for dyad ranking}}}, year = {{2016}}, } @inproceedings{15111, author = {{Pfannschmidt, Karlson and Hüllermeier, Eyke and Held, S. and Neiger, R.}}, booktitle = {{In Proceedings IPMU 16th International Conference on Information Processing and Management of Uncertainty in Knowledge-Based Systems, Part 1, Eindhoven, The Netherlands}}, pages = {{450--461}}, publisher = {{Springer}}, title = {{{Evaluating tests in medical diagnosis-Combining machine learning with game-theoretical concepts}}}, year = {{2016}}, } @article{16041, author = {{Leinweber, M. and Fober, T. and Strickert, M. and Baumgärtner, L. and Klebe, G. and Freisleben, B. and Hüllermeier, Eyke}}, journal = {{IEEE Transactions on Knowledge and Data Engineering}}, number = {{6}}, pages = {{1423--1434}}, title = {{{CavSimBase: A database for large scale comparison of protein binding sites}}}, volume = {{28}}, year = {{2016}}, } @phdthesis{141, author = {{Mohr, Felix}}, publisher = {{Universität Paderborn}}, title = {{{Towards Automated Service Composition Under Quality Constraints}}}, doi = {{10.17619/UNIPB/1-171}}, year = {{2016}}, } @inbook{10214, author = {{Fürnkranz, J. and Hüllermeier, Eyke}}, booktitle = {{Encyclopedia of Machine Learning and Data Mining}}, editor = {{Sammut, C. and Webb, G.I.}}, publisher = {{Springer}}, title = {{{Preference Learning}}}, year = {{2016}}, } @proceedings{10221, editor = {{Hoffmann, F. and Hüllermeier, Eyke and Mikut, R.}}, title = {{{ Proceedings 26.
