(Commission of Motorization and Energetics in Agriculture, 2017) Rybchak, Z.; Basystiuk, O.; Lviv Polytechnic National University
Computer vision and image recognition are one of the most popular theme nowadays. Moreover, this technology developing really fast, so filed of usage increased. The main aims of this article are explain basic principles of this field and overview some interesting technologies that nowadays are widely used in computer vision and image recognition.
Analysis of methods and means of text mining
(Commission of Motorization and Energetics in Agriculture, 2017) Rybchak, Z.; Basystiuk, O.; Lviv Polytechnic National University
In Big Data era when data volume doubled every year analyzing of all this data become really complicated task, so in this case text mining systems, techniques and tools become main instrument of analyzing tones and tones of information, selecting that information that suit the best for your needs and just help save your time for more interesting thing. The main aims of this article are explain basic principles of this field and overview some interesting technologies that nowadays are widely used in text mining.
Optimization of travel routes based on modified genetic and ant algorithms
(Commission of Motorization and Energetics in Agriculture, 2017) Rybchak, Z.; Lviv Polytechnic National University
In the article, propose to use modified mating operators and initialization genetic and ant algorithms to solve transport problems in tourism. The article analyzes modern methods of optimization of routes used to transport tourists between the settlements of view of efficient use of resources. By analyzing the behavior of ant colonies, such as finding the shortest route by providing mating pheromones and features two solutions genetic algorithm developed algorithms for finding the optimal route, costing resources search distance, time, route, storing executed routes. The paper present description created system for mobile phones operating system IOS, which performs all operations listed above.
