Classification of multi-class motor imaginary tasks using poincare measurements extracted from eeg signals. Abstract: Motor Imaginary MI electroencephalography EEG signals are generated with the recording of brain activities when a participant imagines a movement without physically performing it. The correct decoding of MI signals have been became an important task due to the application of these signals in the rehabilitation process of paralyzed patients in recent studies. However, the decoding of the these signals is still an evolving challenge in the design of a brain-computer interface BCI system. In this study, a machine learning based approach using Poincare measurements from non-linear Php Poker Hand Evaluator of MI EEG signals is proposed for classification of four-class MI tasks. The m-lagged Poincare plots were used to extract non-linear features and m is set to be values from 1 to The performances of feature vectors which are extracted from 10 lag values and feature vector which is the combinations of these vectors were investigated separately in experimental evaluation section. The 24 different typical classification algorithms were tested in differentiating MI tasks using 5-fold cross-validation. Each of the these algorithms tested 10 times to analyzed the repeatability of the experimental results. The highest classifier performance of According to average accuracy value of 24 classifiers in 11 feature vector, the most discriminative feature set is 9th vector that consists of features extracted when lag value defined as 9. As a result, the innovative aspect of this study is the application of Poincare plots, one of the nonlinear feature extraction methods, in motor imaginary task classification. Özet: Motor Hayali MH elektroensefalografi EEG sinyalleri, bir katılımcı fiziksel olarak gerçekleştirmeden bir hareketi hayal ettiğinde beyin Php Poker Hand Evaluator kaydedilmesiyle üretilir. Son yıllarda yapılan çalışmalarda bu sinyallerin felçli hastaların rehabilitasyon sürecinde uygulanması nedeniyle MH EEG sinyallerinin doğru çözümlenmesi önemli bir görev haline gelmiştir. Bununla birlikte, bu sinyallerin kodunun çözülmesi, bir Php Poker Hand Evaluator arayüzü BBA sisteminin tasarımında hala gelişen bir zorluktur. Bu çalışmada, dört sınıflı MH görevlerinin sınıflandırılması için MH EEG sinyallerinin doğrusal olmayan ölçümlerinden Poincare ölçümlerini kullanan makine öğrenmesi tabanlı bir yaklaşım önerilmiştir. M-gecikmeli Poincare grafikleri, doğrusal olmayan öznitelikleri çıkarmak için kullanıldı ve m, 1'den 10'a kadar olan değerler olacak şekilde ayarlandı. Bu algoritmaların her biri, deneysel sonuçların tekrarlanabilirliğini analiz etmek için 10 defa test edildi. Sonuç olarak, bu çalışmanın yenilikçi yönü, doğrusal olmayan öznitelik çıkarma yöntemlerinden biri olan Poincare çizimlerinin motor hayali görev sınıflandırmasında uygulanmasıdır.

In the study, the Science and Technology Attitude Scale was used to measure students' attitudes. However, in a specially designed sports branch such as goalball, it is not possible to explain the shooting performance with a single variable. Kinnunen, D. Savas, S. Moreover, the fact that players have visual impairments is considered another factor that causes this relation. Indexing metadata. Almost all the existing correlations were detected in the measurements performed in the case of left leg stance. Players also try to defend their goals with their bodies by making inferences about the velocity and direction of the ball because of the sound of the bell inside. Conducting future studies with the participation of male athletes and with a large number of samples may contribute to the literature. Toward a theory of instruction.
