Table 3.
Performance (in %) for the different models on the holdout data set. Values are averages over 10 trials. Highest values per column are highlighted in bold. Pre-train., pre-training; Class., classifier; Bal. acc., balanced accuracy; Sens., sensitivity; Spec., specificity; AUC, area under the curve of the receiver operating characteristic; les. fill., lesions filled.
