Figure 4
Leave-one-group-out cross-validation. Cross-validation conducted on a leave-one-group-out basis with 25 iterations (each dataset left out in one iteration of training). Percentages show the proportion of pixels that fall into each category summed across each iteration. Numbers show the absolute number of pixels within each category. Unclassified pixels are those which failed to achieve a scaled probability > 0.5. Details about the validation method are provided in “Materials and methods” section.
