question about eq10

Closed this issue a year ago · 4 comments

Hi, dear author, thanks for your great job.

I have a big question about the following equation, since this step aims to calculate the source domain aggregation barycenter, why the coupling γ space is (μ_s, μ_t)? I think it should be (μ_s, μ_b) ?

Hi Helen,

Thank you for your question. Yes, this is actually a typo. It is a coupling between μ_s and μ_b.

ok~ Thanks for your reply!

And I also want to know if this kind of domain adaptation [source domain, target domain] should have same label space? Because I have seen the following equation in your paper.

This is the covariate shift assumption. This is a necessary condition for doing unsupervised domain adaptation (i.e. without target labels). Under this assumption the distributional shift problem can be solved by applying a transformation to the features, while keeping labels unchanged.
