Claim 3:
4. The method according to claim 2, wherein determining 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 comprises:
determining 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;
performing target region extraction on the source domain sampling feature, to obtain a source domain candidate region, and performing target region extraction on the target sampling feature, to obtain a target candidate region;
performing, 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 performing, after performing pooling processing on the target sampling feature and the target candidate region, mapping to obtain a target mapping result;
determining 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
determining 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.
