1. A method for unsupervised domain adaptation, comprising the steps of:
generating a first augmented domain associated with a source domain;
generating a second augmented domain associated with a target domain; and
performing unsupervised domain adaptation by using the first augmented domain and the second augmented domain as a bridge for connecting the source domain and the target domain,
wherein the step of generating the first augmented domain is setting a first ratio that is a fixed mixup ratio for the source domain and generating a mixup sample for the source domain by using the first ratio.
