Title:
BRAIN FUNCTIONAL CONNECTIVITY CORRELATION VALUE CLUSTERING DEVICE, BRAIN FUNCTIONAL CONNECTIVITY CORRELATION VALUE CLUSTERING SYSTEM, BRAIN FUNCTIONAL CONNECTIVITY CORRELATION VALUE CLUSTERING METHOD, BRAIN FUNCTIONAL CONNECTIVITY CORRELATION VALUE CLASSIFIER PROGRAM, BRAIN ACTIVITY MARKER CLASSIFICATION SYSTEM AND CLUSTERING CLASSIFIER MODEL FOR BRAIN FUNCTIONAL CONNECTIVITY CORRELATION VALUES
Document Type and Number:
WIPO Patent Application WO/2021/205996
Kind Code:
A1
Abstract:
A brain functional connectivity correlation value clustering device for clustering subjects which have prescribed attributes on the basis of brain measurement data obtained from a plurality of facilities, wherein: a plurality of MRI devices capture fMRI image data for a healthy group and a patient group during rest; and a calculation processing system 300 performs ensemble learning by creating a discriminator via "supervised learning" between a disease label for each subject and an element value of a correlation matrix subjected to harmonization processing, selects, during the ensemble learning, a characteristic for clustering according to importance from among the characteristics identified during the disease label discriminator creation processing, and upon doing so, executes multiple co-clustering via "unsupervised learning."
