Some questions in paper #16

Yes, the actual code implements 2-crop and multi-crop. The latter includes both large crops and small crops (I guess the small crops is the "local images" you mentioned). The slides illustrate the case for 2-crop for simplicity.
No. The similarity matrix is computed between any two local features (to clarify, it means grid features) between student and teacher. |
Hello, I have been studying your article recently. I noticed that your PPT described pre-train Task 2: region-level as shown in the picture above. But doesn't the actual code input local images into the teacher model. In addition, I am not quite clear about region-level loss function. Is it to calculate the similarity matrix of local features output by student model and global features of teacher model? I hope you can answer my two doubts at your convenience
