Please refer to Section 3.3 of the paper for details, i.e., the paragraph
Negative samples.
Thank you for your reply. I saw this part. Have you tried using the other parts of the two views of the same image as negative samples? This seems more 'hard negative' than sample from a different image.
We didn't try that.
OK. Thank you very much.
I have 1 question and hope to hear from you: In section, 2.3 ''Each negative key t_ is the pooled feature vector of a view from a different image.'' Why not use the other parts of the two views of the same image as negative samples? This seems more make sense.
So the 'pooled feature vector of a view from a different image' means the global average pooled vector of a view from a different image? If so, t_ is equal to the global view of a different image?
