In such situations, there is often not enough space to show complex data with approaches like juxtaposed visualizations. To alleviate this issue, we propose the use of animated transitions between several small-scale visualizations. We discuss design considerations for animated transitions between small-scale visualizations and differences to normal-sized visualizations. Further, we present the results of two online studies on the effectiveness of those animated transitions to convey information and attribute relations, as well as the mental load of following the animated transitions. As a result, we found that animated transitions between visualizations are understandable in small scale, but performance depends on the specific task and the type of operation carried out with the animated transition.}, author = {Huth, Franziska and Blascheck, Tanja and Koch, Steffen and Ertl, Thomas}, day = 28, doi = {10.1007/s12650-023-00937-z}, issn = {1875-8975}, journal = {Journal of Visualization}, month = {08}, title = {Studies and design considerations for animated transitions between small-scale visualizations}, url = {https://doi.org/10.1007/s12650-023-00937-z}, year = 2023 }

  @article{DOERR201587, abstract = {Black-box complexity theory recently produced several surprisingly fast black-box optimization algorithms. In this work, we exhibit one possible reason: These black-box algorithms often profit from solutions inferior to the previous-best. In contrast, evolutionary approaches guided by the “survival of the fittest” paradigm often ignore such solutions. We use this insight to design a new crossover-based genetic algorithm. It uses mutation with a higher-than-usual mutation probability to increase the exploration speed and crossover with the parent to repair losses incurred by the more aggressive mutation. A rigorous runtime analysis proves that our algorithm for many parameter settings is asymptotically faster on the OneMax test function class than all what is known for classic evolutionary algorithms. A fitness-dependent choice of the offspring population size provably reduces the expected runtime further to linear in the dimension. Our experimental analysis on several test function classes shows advantages already for small problem sizes and broad parameter ranges. Also, a simple self-adaptive choice of these parameters gives surprisingly good results.}, author = {Doerr, Benjamin and Doerr, Carola and Huth, Franziska}, doi = {https://doi.org/10.1016/j.tcs.2014.11.028}, issn = {0304-3975}, journal = {Theoretical Computer Science}, pages = {87-104}, title = {From black-box complexity to designing new genetic algorithms.}, url = {http://www.sciencedirect.com/science/article/pii/S0304397514009451}, volume = 567, year = 2015 }

  @article{journals/ijcv/SchmaltzPMEWB14, abstract = {Gali{\'{c}} et al. (Journal of Mathematical Imaging and Vision 31:255--269, 2008) have shown that compression based on edge-enhancing anisotropic diffusion (EED) can outperform the quality of JPEG for medium to high compression ratios when the interpolation points are chosen as vertices of an adaptive triangulation. However, the reasons for the good performance of EED remained unclear, and they could not outperform the more advanced JPEG 2000. The goals of the present paper are threefold: Firstly, we investigate the compression qualities of various partial differential equations. This sheds light on the favourable properties of EED in the context of image compression. Secondly, we demonstrate that it is even possible to beat the quality of JPEG 2000 with EED if one uses specific subdivisions on rectangles and several important optimisations. These amendments include improved entropy coding, brightness and diffusivity optimisation, and interpolation swapping. Thirdly, we demonstrate how to extend our approach to 3-D and shape data. Experiments on classical test images and 3-D medical data illustrate the high potential of our approach.}, author = {Schmaltz, Christian and Peter, Pascal and Mainberger, Markus and Huth, Franziska and Weickert, Joachim and Bruhn, Andrés}, doi = {10.1007/s11263-014-0702-z}, issn = {1573-1405}, journal = {International Journal of Computer Vision}, number = 3, pages = {222-240}, title = {Understanding, Optimising, and Extending Data Compression with Anisotropic Diffusion.}, url = {https://doi.org/10.1007/s11263-014-0702-z}, volume = 108, year = 2014 }

  @inproceedings{Doerr:2013:LBF:2463372.2463480, abstract = {The recently active research area of black-box complexity revealed that for many optimization problems the best possible black-box optimization algorithm is significantly faster than all known evolutionary approaches. While it is not to be expected that a general-purpose heuristic competes with a problem-tailored algorithm, it still makes sense to look for the reasons for this discrepancy. In this work, we exhibit one possible reason---most optimal black-box algorithms profit also from solutions that are inferior to the previous-best one, whereas evolutionary approaches guided by the "survival of the fittest" paradigm often ignore such solutions. Trying to overcome this shortcoming, we design a simple genetic algorithm that first creates λ offspring from a single parent by mutation with a mutation probability that is k times larger than the usual one. From the best of these offspring (which often is worse than the parent) and the parent itself, we generate further offspring via a uniform crossover operator that takes bits from the winner offspring with probability 1/k only. A rigorous runtime analysis proves that our new algorithm for suitable parameter choices on the OneMax test function class is asymptotically faster (in terms of the number of fitness evaluations) than what has been shown for μ +, λ EAs. This is the first time that crossover is shown to give an advantage for the OneMax class that is larger than a constant factor. Using a fitness-dependent choice of k and λ, the optimization time can be reduced further to linear in n. Our experimental analysis on several test function classes shows advantages already for small problem sizes and broad parameter ranges. Also, a simple self-adaptive choice of these parameters gives surprisingly good results.}, acmid = {2463480}, address = {New York, NY, USA}, author = {Doerr, Benjamin and Doerr, Carola and Huth, Franziska}, booktitle = {Proceedings of the 15th Annual Conference on Genetic and Evolutionary Computation}, doi = {10.1145/2463372.2463480}, isbn = {978-1-4503-1963-8}, location = {Amsterdam, The Netherlands}, note = {Best Paper Award}, numpages = {8}, pages = {781-788}, publisher = {ACM}, series = {GECCO '13}, title = {Lessons from the black-box: fast crossover-based genetic algorithms.}, url = {http://doi.acm.org/10.1145/2463372.2463480}, year = 2013 }
