"""Main function of ABMT for the paper: Adversarial Brain Multiplex Prediction From a Single Brain Network with Application to Gender Fingerprinting
View Network Normalization
Details can be found in:
(1) the original paper
Ahmed Nebli, and Islem Rekik.
---------------------------------------------------------------------
This file contains the implementation of three key steps of our netNorm framework:
Inputs:
sourceGraph: (N × m x m) matrix stacking the source graphs of all subjects
(N × m x m) matrix stacking the target graphs of all subjects
N the total number of views
m the number of regions
Output:
Target graph: (N x m x m) matrix stacking predicted target graphs of all subjects
(2) Dependencies: please install the following libraries:
- TensorFlow
- numpy
- scikitlearn
