Classification of ADHD Patients by Kernel Hierarchical Extreme Learning Machine

by   Sartaj Ahmed Salman, et al.

These days, the diagnosis of neuropsychiatric diseases through brain imaging technology has received more and more attention. The exploration of interactions in brain functional connectivity based on functional magnetic resonance imaging (fMRI) data is critical for the study of mental illness. Because attention-deficit/hyperactivity disorder (ADHD) is a chronic disease that affects millions of children, it is difficult to diagnose, so there is still much space for improvement in the accuracy of the diagnosis of the disease. In this paper, we consider the dynamics of brain functional connectivity, modeling a functional brain dynamics model from medical imaging, which helps to find differences in brain function interactions between normal control (NC) children and ADHD children. In more detail, our method is used by Bayesian Connectivity Change Point Model for dynamic detection, Local Binary Encoding Method for local feature extraction, and Kernel Hierarchical Extreme Learning Machine implementation classification. To validate our approach, experimental comparisons of fMRI imaging data on 23 ADHD and 45 NC children were performed, and our experimental methods achieved better classification results than existing methods.
