A Novel Functional Brain Connectivity Network Classification Method
Connections in the human brain can be examined efficiently using brain imaging techniques such as Diffusion Tensor Imaging (DTI), Resting-State fMRI. Brain connectivity networks are constructed by using image processing and statistical methods, these networks explain how brain regions interact with each other. Brain networks can be used to train machine learning models that can help the diagnosis of neurological disorders.
In functional brain graphs, the nodes describe the regions and the edge weights correspond to the values of correlation coefficients of the time-series of the two nodes associated with the edges.
