Fig. 5.

Training (green) and validation (red) curves on ellipse bounding box tumor data as a function of epochs for both case studies. Early stopping strategy was used, where blue dot points to the epoch whose parameters were used for test set. Left: For US dataset, the validation curve converged at epoch = 67. Right: For TCGA dataset, the validation curve converged at epoch = 76, after which the validation losses didn’t improve
