Claim 13:
14. The apparatus according to claim 12, wherein, when the processor is configured to cause the apparatus to determine the MMD-based discrepancy loss between the source domain data and the target domain data according to the source domain sampling feature and the target sampling feature, the processor is configured to cause the apparatus to:
determine a first MMD-based discrepancy loss between the source domain data and the target domain data according to the source domain sampling feature and the target sampling feature;
perform target region extraction on the source domain sampling feature, to obtain a source domain candidate region, and perform target region extraction on the target sampling feature, to obtain a target candidate region;
perform, after performing pooling processing on the source domain sampling feature and the source domain candidate region, mapping to obtain a source domain mapping result, and perform, after performing pooling processing on the target sampling feature and the target candidate region, mapping to obtain a target mapping result;
determine a second MMD-based discrepancy loss between the source domain data and the target domain data according to the source domain mapping result and the target mapping result; and
determine the MMD-based discrepancy loss between the source domain data and the target domain data according to the first MMD-based discrepancy loss and the second MMD-based discrepancy loss.
