Figure 3

U-matrix visualization of the SOFM after training. Eleven wear pattern clusters were identified. Five out of six in vitro tested components were assigned to cluster “1”. The number of revised (R), postmortem (P), and simulator (S) components and the total percentage (%) of components assigned to each group are noted in brackets [R, P, S, %]. Light map colors represent cluster areas (valleys), while darker colors represent cluster boundaries (hills).
