“…To address the issue of network threshold selection, a set of brain network analysis methods called graph filtration based on persistent homology (Chen & Edelsbrunner, ; Edelsbrunner & Harer, ; Wu et al, ) has been proposed to measure persistent brain network topology features generated over all possible thresholds (Choi et al, ; Chung, Hanson, Ye, Davidson, & Pollak, ; Lee et al, ; Lee, Kang, Chung, Kim, & Lee, ; Yoo et al, ). It quantifies various persistent topological features at different scales in a coherent manner and avoids the thresholding selection.…”
