Multi-modal Graph Neural Network for Early Diagnosis of Alzheimer's Disease from sMRI and PET Scans

no code implementations31 Jul 2023 Yanteng Zhanga, Xiaohai He, Yi Hao Chan, Qizhi Teng, Jagath C. Rajapakse

In this study, we demonstrate how brain networks can be created from sMRI or PET images and be used in a population graph framework that can combine phenotypic information with imaging features of these brain networks.

Marshall-Olkin Power-Law Distributions in Length-Frequency of Entities

1 code implementation8 Nov 2018 Xiaoshi Zhong, Xiang Yu, Erik Cambria, Jagath C. Rajapakse

Entities have different forms in different linguistic tasks and researchers treat those different forms as different concepts.
