Understanding of a brain spatial map based on threshold-free function dendrogramization
Hyekyoung Lee, Hyejin Kang, Youngmin Huh +2
Linear matrix factorizations (LMFs) such as independent component analysis (ICA), principal component analysis (PCA), and their extensions, have been widely used for finding releva…

Harmonic holes as the submodules of brain network and network dissimilarity
Hyekyoung Lee, Moo K. Chung, Hongyoon Choi +4
Persistent homology has been applied to brain network analysis for finding the shape of brain networks across multiple thresholds. In the persistent homology, the shape of networks…

Topological Brain Network Distances
Moo K. Chung, Hyekyoung Lee, Andrey Gritsenko +4
Existing brain network distances are often based on matrix norms. The element-wise differences in the existing matrix norms may fail to capture underlying topological differences.…
