Fig. 9: Tile-level cross-classification correlations for TP53 mutational status.

Row labels denote the cancer type used to train the first TP53 mutation classifier. Column labels denote both the test tissue and the tissue of the second TP53 classifier. Heatmap values indicate correlation coefficients of mutation probability logits between the two classifiers on the test tissue. Numbers at the bottom and right show column and row averages, respectively, with diagonal values excluded.
