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 = {{Wever, Marcel Dominik and Mohr, Felix and Hüllermeier, Eyke}}, booktitle = {{Proceedings of the Genetic and Evolutionary Computation Conference, GECCO 2018, Kyoto, Japan, July 15-19, 2018}}, keywords = {{Classification, Hierarchical Decomposition, Indirect Encoding}}, location = {{Kyoto, Japan}}, publisher = {{ACM}}, title = {{{Ensembles of Evolved Nested Dichotomies for Classification}}}, doi = {{10.1145/3205455.3205562}}, year = {{2018}}, } @inproceedings{21173, author = {{Bonfert, Michael and Spliethöver, Maximilian and Arzaroli, Roman and Lange, Marvin and Hanci, Martin and Porzel, Robert}}, booktitle = {{Proceedings of the 20th ACM International Conference on Multimodal Interaction}}, isbn = {{9781450356923}}, title = {{{If You Ask Nicely: A Digital Assistant Rebuking Impolite Voice Commands}}}, doi = {{10.1145/3242969.3242995}}, year = {{2018}}, } @article{21190, author = {{Engelkemeier, Katja and Hoyer, Kay-Peter and Schaper, Mirko}}, issn = {{0167-577X}}, journal = {{Materials Letters}}, pages = {{752--756}}, title = {{{Influence of sp3/sp2-carbon ratio of vertically standing carbon nanostructures produced by pulsed laser-treatment on PAN-based carbon fibers}}}, doi = {{10.1016/j.matlet.2018.11.041}}, year = {{2018}}, } @article{21191, author = {{Camberg, Alan A. and Engelkemeier, Katja and Dietrich, Jan and Heggemann, Thomas}}, issn = {{2510-2877}}, journal = {{Lightweight Design worldwide}}, pages = {{24--29}}, title = {{{Top-down design of tailored fiber-metal laminates}}}, doi = {{10.1007/s41777-018-0004-1}}, year = {{2018}}, } @article{21193, author = {{Engelkemeier, Katja and Mücke, Christian and Hoyer, Kay Peter and Schaper, Mirko}}, issn = {{2522-0128}}, journal = {{Advanced Composites and Hybrid Materials}}, pages = {{189--199}}, title = {{{Anodizing of electrolytically galvanized steel surfaces for improved interface properties in fiber metal laminates}}}, doi = {{10.1007/s42114-018-0071-0}}, year = {{2018}}, } @article{21305, author = {{Mirbabaie, Milad and Stieglitz, Stefan and Priesmeyer, Jessica and Kindel, Marius}}, issn = {{1436-3011}}, journal = {{HMD Praxis der Wirtschaftsinformatik}}, pages = {{147--159}}, title = {{{Einsatz von Spielmechaniken und Bots zur Moderation von Kreativitätsprozessen in Unternehmen}}}, doi = {{10.1365/s40702-018-00475-5}}, year = {{2018}}, } @article{21307, author = {{Stieglitz, S. and Mirbabaie, Milad and Ross, B. and Neuberger, C.}}, journal = {{International Journal of Information Management}}, pages = {{156--168}}, title = {{{Social Media Analytics -
