Hi! Thanks for your great work! Is harder example mining a method from a published paper? If yes, can you tell me the name of this paper? Thanks

No, it originates from my project, which is a improved version of hard example mining. The principle of mathematics can be seen in docs link

    You add the two lines：
    dist_ap *= (1.0 + self.hard_factor)
    dist_an *= (1.0 - self.hard_factor)
    then, it becomes harder triplet loss?
