Thus, the need to both understand and use neural networks is appearing at an ever-increasing rate across all computer science courses. Our objectives in this project were to create a framework for creating and training neural networks for solving different problems real-life problems and for research and education, as well as to investigate the usability of our framework. To provide an easy to use framework, this research recruited five instructors who have taught ANNs at two universities. We asked thirty-one students who have previously studied neural networks to fill out an online survey about what were "the major difficulties in learning NNs" and the "key requirements in a Visual Learning Tool including the most desired features of a visualization tool for explaining NNs" they would have used during the course. We also conducted an observational study to investigate how our students would use this system to learn about ANNs. The visual presentation of ANNs created in our framework can be represented in an Augmented Reality (AR) and Virtual Reality (VR) environment thus allowing us to use a virtual space to display and manage networks. An evaluation of the effect of the AR/VR experience through a formative test and survey showed that the majority of students had a positive response to the engaging and interactive features of our framework (RKNet). © 2023, The Author(s).}, keywords = {VISUALIZATION; education; Virtual reality; artificial neural network; Augmented reality}, year = {2024}, eissn = {1573-7608}, orcid-numbers = {Király, Roland/0009-0005-5500-2622} } @inbook{MTMT:34554237, title = {Milyen változásokat hozhatnak a kvantumszámítógépek az oktatás területén?}, url = {https://m2.mtmt.hu/api/publication/34554237}, author = {Prantner, Csilla and Koczka, Ferenc and Biró, Csaba}, booktitle = {Módszerek a fenntarthatóság jegyében}, doi = {10.46403/Modszerekafenntarthatosagjegyeben.2023.143}, unique-id = {34554237}, year = {2023}, pages = {149-163} } @article{MTMT:34534646, title = {Integer Programming Based Optimization of Power Consumption for Data Center Networks}, url = {https://m2.mtmt.hu/api/publication/34534646}, author = {Kovásznai, Gergely and Al-Shamarti, Mohammed}, doi = {10.14232/actacyb.299115}, journal-iso = {ACTA CYBERN-SZEGED}, journal = {ACTA CYBERNETICA}, unique-id = {34534646}, issn = {0324-721X}, abstract = {With the quickly developing data centers in smart cities, reducing energy consumption and improving network performance, as well as economic benefits, are essential research topics. In particular, Data Center Networks do not always run at full capacity, which leads to significant energy consumption. This paper experiments with a range of optimization tools to find the optimal solutions for the Integer Linear Programming (ILP) model of network power consumption. The study reports on experiments under three communication patterns (near, long, and random), measuring runtime and memory consumption in order to evaluate the performance of different ILP solvers.While the results show that, for near traffic pattern, most of the tools rapidly converge to the optimal solution, CP-SAT provides the most stable performance and outperforms the other solvers for the long traffic pattern. On the other hand, for random traffic pattern, Gurobi can be considered to be the best choice, since it is able to solve all the benchmark instances under the time limit and finds solutions faster by 1 or 2 orders of magnitude than the other solvers do.}, year = {2023}, eissn = {2676-993X} } @inproceedings{MTMT:34441886, title = {Szemelvények egy felsőoktatási rendszer informatikai védelmének tapasztalataiból}, url = {https://m2.mtmt.hu/api/publication/34441886}, author = {Koczka, Ferenc}, booktitle = {Új technológiákkal, új tartalmakkal a jövő digitális transzformációja felé}, doi = {10.31915/NWS.2023.14}, unique-id = {34441886}, year = {2023}, pages = {91-98} } @CONFERENCE{MTMT:34194205, title = {Klasszikus és kvantum logikai kapuk oktatása a Programtervező informatikus BSc képzésben}, url = {https://m2.mtmt.hu/api/publication/34194205}, author = {Bakos, Rózsa Ajándék and Biró, Csaba}, booktitle = {Agria Média 2023 ICI 17}, unique-id = {34194205}, year = {2023}, pages = {18-18} } @article{MTMT:33831304, title = {Educational Issues Raised by the Availability of the Quantum Computer}, url = {https://m2.mtmt.hu/api/publication/33831304}, author = {Koczka, Ferenc and Prantner, Csilla and Biró, Csaba}, doi = {10.36427/CEJNTREP.5.1.5051}, journal-iso = {CEJ-NETREP}, journal = {CENTRAL-EUROPEAN JOURNAL OF NEW TECHNOLOGIES IN RESEARCH EDUCATION AND PRACTICE}, volume = {5}, unique-id = {33831304}, abstract = {The development of quantum computers is bringing major changes to the IT sector.
