Abstract
This paper focuses on classification of motor imagery in Brain Computer Interface (BCI) by using classifiers from machine learning technique. The BCI system consists of two main steps which are feature extraction and classification. The Fast Fourier Transform (FFT) features is extracted from the electroencephalography (EEG) signals to transform the signals into frequency domain. Due to the high dimensionality of data resulting from the feature extraction stage, the Linear Discriminant Analysis (LDA) is used to minimize the number of dimension by finding the feature subspace that optimizes class separability. Five classifiers: Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Naive Bayes, Decision Tree and Logistic Regression are used in the study. The performance was tested by using Dataset 1 from BCI Competition IV which consists of imaginary hand and foot movement EEG data. As a result, SVM, Logistic Regression and Naive Bayes classifier achieved the highest accuracy with 89.09% in AUC measurement.

Motor imagery classification in brain-machine interface with machine learning algorithms: Classical approach to multi-layer perceptron model

TL;DR: Wang et al. as discussed by the authors proposed a subject-independent generalized MLP model with ≈90% accuracy and half the classification time compared to traditional ML-based models, which suggests the possibility of a much accurate and robust generalized BCI (subject independent) if this model integrates sophisticated optimization.
