Fig 9. Validation and testing AUC for slide-level classification in low and high-risk ODX using BCR-Net with different sample size K.

Fig 9

(a) Mean cross-validation AUC of 5-fold cross-validation for H&E-stained slides and LTOCV for Ki67-stained slides. The best validation AUC for H&E-stained slides is 0.875 with K = 5000. The best validation AUC for Ki67 stained slides is 0.811 with K = 3000. (b) Mean hold-out testing AUC of 5-fold cross-validation for H&E-stained slides. The best testing AUC for H&E-stained slides is 0.775 with K = 5000.
