Before revision:  which is more efficient than the OTCE score and more accurate than the OT-based NCE score . Specifically, we build the joint correspondences between source and target data via solving an optimal transport problem with  considering both the sample distance and label distance, and then compute the transferability score as the negative conditional entropy  .
