AINU trained with dual-colour Pol II and H3 images was challenged on a test set of 71 previously unseen images having the nucleoli occluded by filling them with cloned non-nucleolous regions from the same image. Normalized confusion matrix (with numbers of positively and negatively predicted images in the parentheses). Precision and recall plots for the somatic cell ( g ) and hiPSC ( h ) classes, reporting the overall AP.
