Re-ranking network about superglobal

I understand the beta settings! But what I don't know is that gi is implemented by calculating distances between database features?

Hi. Thanks for liking our work! $g_*$'s across this paper denote the global features of given images. The similarities between g's are determined by the dot product with the vectors g's being of unit length.

Thank you for your excellent work. I still don’t understand it. It seems that your reordering network does not require training and has no corresponding loss.
