Originální abstrakt

The focus of this paper is to compare several common machine learning classi cation algorithms for Optical Character Recognition of CAPTCHA codes. The main part of a research focuses on the comparative study of Neural Networks, k-Nearest Neighbour, Support Vector Machines and Decision Trees implemented in MATLAB Computing environment. Achieved success rates of all analyzed algorithms overcome 89%. The main di erence in results of used algorithms is within the learning times. Based on the data found, it is possible to choose the right algorithm for the particular task.
