poor performance on Asian faces

I'm try to compute the cosine similarity of a couple of Asian faces, but it seems facenet can be confused by these faces (two total different faces can have 0.7 or higher cosine similarity). Is this normal or I am missing something ?

If I train facenet on a Asian Face dataset, will it help this problem?

Currently I only have a gtx1050 at hand, will it be sufficient to train the facenet?

Thanks
