Caption: Figure 5.

Similar to Figure 4, but now also showing results for models trained on a restricted set of reference ages (log(age) = 7.0–9.5), in which the youngest and oldest clusters have been excluded (right panel of bar charts). Cases 1 and 4–8 are reproduced from Figure 4 in the left panel of bar charts. Two additional occlusion experiments using the full five-filter input are added (Cases 2 and 3 in this figure), applying outer and inner masking, respectively.
