2.4. Comparisons with the State-of-the-art Methods

We compared our model with three state-of-the-art models using AUC, i.e. Resnet50 [37], DANN [38], and Deep Coral [25]. Dataset, P-x, was used as the source domain. Our local cohort datasets, LC-A and LC-B, acted as the target domains. The individual (i.e. T2, ADC, and hDWI) and the ensembled (i.e. T2 + ADC + hDWI) sequences were involved. The other ensembled sequences, T2 + ADC, T2 + hDWI, and ADC + hDWI were not involved here due to their inferior performance as discussed in Section 4.2. Detailed comparison results are summarized in Table 5 .
