Overview of Cluster Generation, Transfer, and Concordance Assessment. For each
cohort, 23 “source” clustering solutions (S1 to S23) are
generated (total of 230 solutions across the 10 cohorts). Each solution is
transferred to the other cohorts via a predictive model (T1 to T23). Each
solution is also labeled according to its parent cohort, thus source solution 1
from cohort 1 = S1C1. Each cohort ultimately produces 230 cluster
solutions (23 source solutions, and 207 transferred solutions which are
“predicted into” each cohort). The green, red, and dark blue
colors correspond to cluster results generated by a specific cluster method and
set of parameters (for example, “k-medoids with
k=2”).
