--- _id: '46308' abstract: - lang: eng text: Single-objective continuous optimization can be challenging, especially when dealing with multimodal problems. This work sheds light on the effects that multi-objective optimization may have in the single-objective space. For this purpose, we examine the inner mechanisms of the recently developed sophisticated local search procedure SOMOGSA. This method solves multimodal single-objective continuous optimization problems based on first expanding the problem with an additional objective (e.g., a sphere function) to the bi-objective domain and subsequently exploiting local structures of the resulting landscapes. Our study particularly focuses on the sensitivity of this multiobjectivization approach w.r.t. (1) the parametrization of the artificial second objective, as well as (2) the position of the initial starting points in the search space. As SOMOGSA is a modular framework for encapsulating local search, we integrate Nelder–Mead local search as optimizer in the respective module and compare the performance of the resulting hybrid local search to its original single-objective counterpart. We show that the SOMOGSA framework can significantly boost local search by multiobjectivization. Hence, combined with more sophisticated local search and metaheuristics, this may help solve highly multimodal optimization problems in the future. author: - first_name: Pelin full_name: Aspar, Pelin last_name: Aspar - first_name: Vera full_name: Steinhoff, Vera last_name: Steinhoff - first_name: Lennart full_name: Schäpermeier, Lennart last_name: Schäpermeier - first_name: Pascal full_name: Kerschke, Pascal last_name: Kerschke - first_name: Heike full_name: Trautmann, Heike id: '100740' last_name: Trautmann orcid: 0000-0002-9788-8282 - first_name: Christian full_name: Grimme, Christian last_name: Grimme citation: ama: 'Aspar P, Steinhoff V, Schäpermeier L, Kerschke P, Trautmann H, Grimme C.

To open the “data-science-black-box” for lower secondary school students we developed a data science project focussing on the analysis of self-collected environmental data. We embed this project in computer science education, which enables us to use a new knowledge-based programming approach for the data analysis within Jupyter Notebooks and the programming language Python. In this paper, we evaluate the second cycle of this project which took place in a ninth-grade computer science class. In particular, we present how the students coped with the professional tool of Jupyter Notebooks for doing statistical investigations and which insights they gained. article_number: '6' author: - first_name: SUSANNE full_name: PODWORNY, SUSANNE last_name: PODWORNY - first_name: SVEN full_name: HÜSING, SVEN last_name: HÜSING - first_name: CARSTEN full_name: SCHULTE, CARSTEN last_name: SCHULTE citation: ama: 'PODWORNY S, HÜSING S, SCHULTE C.

Decision trees are a method that can foster a preformal understanding of machine learning. We developed an exploratory teaching unit introducing decision trees in grade 6 along the question “How can Artificial Intelligence help us decide whether food is rather recommendable or not?” Students’ performances in an assessment task and self-assessment show that young learners can use a decision tree to classify new items and that they found the corresponding teaching unit informative. author: - first_name: Susanne full_name: Podworny, Susanne last_name: Podworny - first_name: Yannik full_name: Fleischer, Yannik last_name: Fleischer - first_name: Sven full_name: Hüsing, Sven last_name: Hüsing citation: ama: 'Podworny S, Fleischer Y, Hüsing S.

This study represents an in-depth analysis of students’ creation and documentation of machine learning models. The students were supported by educationally designed Jupyter Notebooks, which are used as worked examples. Using the worked example, students document their results in a so-called computational essay. We examine which aspects of creating computational essays are difficult for students to find out how worked examples should be designed to support students without being too prescriptive. We analyze the computational essays produced by students and draw consequences for redesigning our worked example. author: - first_name: Yannik full_name: Fleischer, Yannik last_name: Fleischer - first_name: Sven full_name: Hüsing, Sven last_name: Hüsing - first_name: Rolf full_name: Biehler, Rolf last_name: Biehler - first_name: Susanne full_name: Podworny, Susanne last_name: Podworny - first_name: Carsten full_name: Schulte, Carsten last_name: Schulte citation: ama: 'Fleischer Y, Hüsing S, Biehler R, Podworny S, Schulte C.

However, sensitive personal information, such as documents with people{’}s profiles or relationships as edges, are prone to privacy leaks, as the trained model might reveal the original input. Although differential privacy (DP) offers a well-founded privacy-preserving framework, GCNs pose theoretical and practical challenges due to their training specifics. We address these challenges by adapting differentially-private gradient-based training to GCNs and conduct experiments using two optimizers on five NLP datasets in two languages. We propose a simple yet efficient method based on random graph splits that not only improves the baseline privacy bounds by a factor of 2.7 while retaining competitive F1 scores, but also provides strong privacy guarantees of epsilon = 1.0. We show that, under certain modeling choices, privacy-preserving GCNs perform up to 90{%} of their non-private variants, while formally guaranteeing strong privacy measures. author: - first_name: Timour full_name: Igamberdiev, Timour last_name: Igamberdiev - first_name: Ivan full_name: Habernal, Ivan id: '101881' last_name: Habernal citation: ama: 'Igamberdiev T, Habernal I.

In practice, existing systems may lack the means to validate their privacy-preserving claims, leading to problems of transparency and reproducibility. We introduce DP-Rewrite, an open-source framework for differentially private text rewriting which aims to solve these problems by being modular, extensible, and highly customizable. Our system incorporates a variety of downstream datasets, models, pre-training procedures, and evaluation metrics to provide a flexible way to lead and validate private text rewriting research. To demonstrate our software in practice, we provide a set of experiments as a case study on the ADePT DP text rewriting system, detecting a privacy leak in its pre-training approach. Our system is publicly available, and we hope that it will help the community to make DP text rewriting research more accessible and transparent. author: - first_name: Timour full_name: Igamberdiev, Timour last_name: Igamberdiev - first_name: Thomas full_name: Arnold, Thomas last_name: Arnold - first_name: Ivan full_name: Habernal, Ivan id: '101881' last_name: Habernal citation: ama: 'Igamberdiev T, Arnold T, Habernal I.

Ultrasonic Lamb waves are excited via the thermoelastic effect using laser radiation and detected by a piezoelectric transducer. The resulting measurement data is transformed to yield information about multiple propagating Lamb waves as well as their attenuation. These results are compared to simulation results in an inverse procedure to identify the parameters of an elastic and a viscoelastic material model." author: - first_name: Sarah full_name: Johannesmann, Sarah id: '29190' last_name: Johannesmann - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X - first_name: Nadine full_name: Feldmann, Nadine id: '23082' last_name: Feldmann - first_name: Henning full_name: Zeipert, Henning id: '32580' last_name: Zeipert - first_name: Bernd full_name: Henning, Bernd id: '213' last_name: Henning citation: ama: Johannesmann S, Claes L, Feldmann N, Zeipert H, Henning B.
