@biubug6 Hello! After reading the code, I have a question about the ratio of HEM. I see that the ratio of positive and negative samples is set to 1:3 in SSD, why do you set the ratio of positive and negative samples to 1:7? I would appreciate it if you could reply. Thank you very much.

@biubug6 Also, why set threshold to 0.35 rather than 0.5? I would appreciate it if you could reply.
