WebJan 1, 2024 · From these preprocessed EEG signals, it is necessary to extract significant features. In the time domain, the extraction of the statistical parameters such as mobility, activity and complexity is done from the EEG signals. The binary classification of the guilty and innocent classes in performed using k-nearest neighbor classifier. The nearest neighbor graph (NNG) is a directed graph defined for a set of points in a metric space, such as the Euclidean distance in the plane. The NNG has a vertex for each point, and a directed edge from p to q whenever q is a nearest neighbor of p, a point whose distance from p is minimum among all the given points other than p itself.
