In this paper, we compare three different models of multilayer neural networks in terms of their success in the classification phase. These models were designed for EmguCV, ML.NET and Tensorflow.Net libraries, which are currently among the most widely used libraries in the implementation of an automatic recognition system. Using the EmguCV library,...

Project
The INNO3D project aims to develop tools to train Librarians in using 3D printing so that they have the skills to train library users to use 3D Printing effectively. This will be a dedicated service offered in libraries by librarians who as a result of the training that the INNO3D project will provide, will be able to instruct all library users in the use of 3D printing. The project will enhance the quality and relevance of knowledge and skills of librarians in the area of 3D Printing. The project is designed to improve and diversify the services offered to users of university and other libraries by offering these library users key skills and the opportunity to develop 3D printing competencies. This will be achieved by training librarians who will then train library users, students, staff and citizens in general to use 3D Printing services. Libraries have always been communal spaces that have been set up to share and give access to learning and enrichment resources. The introduction of new technologies such as 3D printing is part of the mission to teach 21st-century skills. 3D printing is an example of the type of resource that will transform today’s libraries into cutting-edge learning hubs and give communities access to technologies that will have a significant impact on such fields as scientific research, architecture, manufacturing, engineering, healthcare and more. Its important to note that the goal of 3D printing in libraries is not to create the next artificial heart. But a library user can learn the technology and potential of digital fabrication and reinforce that learning with simpler hands-on projects. Hence, effectively introducing 3D printing in Society and making it available to ordinary citizens.
Project
- find procedures for identifying fictional, false, and misinformation messages in the web environment primarily in the fleet type - find software and hardware tools for identifying emotions (facial expressions, changing body parameters, etc.) - identify the potential for linking fake news and emotions (project is supported by Scientific Grant Agency of the Ministry of Education of the Slovak Republic within the Operational Program Research and Innovation)
Project
The aim of the project is to design an Internet of Things (IoT) sensor network to monitor the emotional state of the individual students, to verify the functionality of the proposed system, and to implement innovative methods in education and to adapt the learning materials based on acquired data from the sensor network. New content and methodology that develops students' analytical and creative thinking by streamlining the learning processes in applied computer science will later be reflected by professional practice, and by greater erudition. Thanks to innovative methods, it will be possible to effectively provide a higher level of knowledge for students during the teaching process. New materials will be created for a virtual environment that will be adapted by the learning content in real time based on the results from sensor networks that will monitor the current emotional state of the student. The aim of the project is also to improve e-learning, specifically by modifying existing tools, as well as designing and creating new activities that will promote learners' interactivity with learning materials and learning tasks. Another important objective of the project is to solve IoT (smart technology) problems that can be used to popularize science and research, which has the potential to raise public interest and attract students to study computer science on universities.
