BCI: Classifiers Optimization for EEG Signals Acquiring in Real-Time

An enhanced EEG prediction system for motor cortex-imagery tasks using SVM

“…Traditional artificial neural networks that are based on the lowest empirical risk outperform the SVM since it is based on the smallest structural risk. This classifier's purpose is to find the best hyperplane for distinguishing each mode class [1,2,3]. The SVM chooses hyperplanes that group the most points of the same class together while keeping the gap between each class and those hyperplanes as little as possible.…”

“…The support vector is created using the hyperplane's nearest point. The shortest path between them and class points is the distance from the class to the hyperplane [1,2,3]. This is how far something is measured.…”

“…GWO is a collective intelligence program that imitates the predatory behaviour of grey wolves (Tripathi et al, 2018). GWO uses a population-based natural-inspired method, which was created by Mirjalili et al [2,13]. Grey wolves are assigned varying levels of prey and hunting behaviours such as fencing, hunting, and attack based on their social rank, resulting in a global optimization process.…”

“…The performance of detection and prediction is measured using the metrics as illustrated in Table 1: The most widely used method for comparing algorithm performance in classification without class concentration. As a result, prediction accuracy (AC) is the most frequent means of experiencing to avoid separating the number of excellent labels between distinct tasks [2,3]:…”

“…These signals are then converted into control commands for a variety of applications, such as virtual reality (VR) navigation, computer cursor movement, wheelchair motion, robot control, and prosthesiology [1,5,9,12,14]. The GWO algorithm [2] was utilized to establish an appropriate combination of SVM parameters as illustrated in Figure 1, and acquisition signals were classified to found the best ten electrodes with accuracy values remaining 99% in this current work. The following is a breakdown of the rest of the article.…”
