В исследовании приняли участие 6 здоровых испытуемых. Для классификации паттернов была выбрана биоэлектрическая активность в сенсомоторной коре (отведения C3, Cz) в полосе пропускания 0,53-30 Гц и временном окне 1600 мс (450 мс после предъявления разрешающего стимула). Произведена оценка точности классификации паттернов ЭЭГ, соответствующих реальным и воображаемым движениям большого и указательного пальцев, с помощью метода опорных векторов с использованием линейной и радиальной базисной функций. Показана возможность различения паттернов воображаемых движений пальцев одной руки на основе метода опорных векторов (средняя точность 44,7±11,4 % при суммировании 20 проб).</p></abstract><trans-abstract xml:lang="en"><p>Background. The article considers the possibility of distinguishing the electroencephalogram (EEG) patterns associated with real and imagined movements by the right hand fingers with the support vectors method (SVM) for use in the development of the «brain-computer» interface. Methods. Six healthy subjects performed the real and imaginary pressing by the thumb and forefinger of the right hand. The researchers analyzed EEG sensorimotor cortex (C3 and Cz) in the time window 1600 ms after 750 ms from the beginning of the test. Indications for the classification were generated according to the 1st trial signals and when summing up 3, 5, 10 and 20 trials of the same type. For classification were applied linear SVM and SVM based on radial basis function. Results. The average accuracy of movements classification exceeded statistically random threshold and increased with the number of trials (average 44.7±11.4 % when summing up 20 trials). Maximum classification accuracy using a linear SVM was 58.1±5.5 %, RBF SVM - 57.8±5.8 %. Recognition accuracy by 1 and 20 trials for SVM based on radial basis function was higher than that for the linear SVM. Conclusions. The authors show the possibility of distinguishing between EEG patterns of imagined movements by one hand fingers using SVM-classifier.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интерфейс «мозг-компьютер»</kwd><kwd>линейный метод опорных векторов</kwd><kwd>радиальная базисная функция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>“brain-computer” interface</kwd><kwd>linear method of support vectors</kwd><kwd>radial basis function</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каплан А.Я., Кочетова А.Г., Шишкин С.Л.
