Self-supervised learning in computer vision applications
Vančo, Timotej ; Richter, Miloslav (oponent) ; Janáková, Ilona (vedoucí práce)
The aim of the diploma thesis is to make research of the self-supervised learning in computer vision applications, then to choose a suitable test task with an extensive data set, apply self-supervised methods and evaluate. The theoretical part of the work is focused on the description of methods in computer vision, a detailed description of neural and convolution networks and an extensive explanation and division of self-supervised methods. Conclusion of the theoretical part is devoted to practical applications of the Self-supervised methods in practice. The practical part of the diploma thesis deals with the description of the creation of code for working with datasets and the application of the SSL methods Rotation, SimCLR, MoCo and BYOL in the role of classification and semantic segmentation. Each application of the method is explained in detail and evaluated for various parameters on the large STL10 dataset. Subsequently, the success of the methods is evaluated for different datasets and the limiting conditions in the classification task are named. The practical part concludes with the application of SSL methods for pre-training the encoder in the application of semantic segmentation with the Cityscapes dataset.
Development of an IoT System for Home Appliances
Vančo, Timotej ; Kaczmarczyk, Václav (oponent) ; Lázna, Tomáš (vedoucí práce)
The aim of the bachelor thesis is to make a research of the current state of IoT and then propose the creation of my own IoT solution for smart home. It also aims to select the appropriate components for the custom solution from which the system will compose and design an appropriate communications interface with option to secure communicate with each other. Then revive the hardware of sensor modules, actuators and control system. The system should be capable of displaying measured data and enabling actuators to control. The final goal is to control the system with voice commands. The theoretical part is focused on description of what is IoT, history, usage and near future of IoT. Furthermore, the currently used IoT classifications and IoT systems in smart homes are described from a commercial and open-source perspective. The theoretical part ends with the comparison of voice assistants and the way the text is understood by the computer. The practical part deals with the description of own solution, selection of components for modules, creation of printed circuits, designing boxes for 3D printing, creation software for individual modules for measurement, communication and control of intelligent home. Next, I am writing about a system that displays measured values from modules, creates a user interface, and controls action members using buttons or voice commands.
