Clustering Students According to their Academic Achievement Using Fuzzy Logic
Serhiy Balovsyak, Oleksandr Derevyanchuk, Hanna Kravchenko +2
The software for clustering students according to their educational achievements using fuzzy logic was developed in Python using the Google Colab cloud service. In the process of a…
On Shor's r-Algorithm for Problems with Constraints
Vladimir Norkin, Anton Kozyriev
Shor's r-algorithm (Shor, Zhurbenko (1971), Shor (1979)) with space stretching in the direction of difference of two adjacent subgradients is a competitive method of nonsmooth opti…
Short cycles of random permutations with cycle weights: point processes approach
Oleksii Galganov, Andrii Ilienko
We study the asymptotic behavior of short cycles of random permutations with cycle weights. More specifically, on a specially constructed metric space whose elements encode all pos…
Size-Induced High Electrocaloric Response of Dense Ferroelectric Nanocomposites
Anna N. Morozovska, Oleksandr S. Pylypchuk, Serhii Ivanchenko +9
Analytical results obtained within Landau-Ginzburg-Devonshire approach and effective media models, predict that the synergy of size effects and Vegard stresses can significantly en…
Reset thresholds of transformation monoids
Igor Rystsov, Marek Szykuła
Motivated by the Černý conjecture for automata, we introduce the concept of monoidal automata, which allows the formulation of the Černý conjecture for monoids. We show upper bound…
Spin exchange dynamics in 4H SiC monocrystals with different nitrogen donor concentrations
M. Holiatkina, A. Pöppl, E. Kalabukhova +2
4H silicon carbide (SiC) polytype is preferred over other SiC polytypes for high-power, high-voltage, and high-frequency applications due to its superior electrical, thermal, and s…
Approaches to Improving the Accuracy of Machine Learning Models in Requirements Elicitation Techniques Selection
Denys Gobov, Olga Solovei
Selecting techniques is a crucial element of the business analysis approach planning in IT projects. Particular attention is paid to the choice of techniques for requirements elici…
Predicting the Geolocation of Tweets Using transformer models on Customized Data
Kateryna Lutsai, Christoph H. Lampert
This research is aimed to solve the tweet/user geolocation prediction task and provide a flexible methodology for the geotagging of textual big data. The suggested approach impleme…
