Prepare for Nov 13th report

[hanfeisun]

• strong pair vs soft pair-
• pretrained vs non-pretrained & L2_loss
• encoder_freeze vs encoder_not_freeze
• softpair+ vs softpair- vs no pair

[hanfeisun]

• When the overlap rate decreases, how the performance deteriorate?
• Calligraphy vs Sans-Serif vs Serif
• Chinese vs Korean

[hanfeisun]

• For evaluation, add L2 loss
• Use OCR as encoder? Use LSH as encoder? Use LSH for pairing?

[hanfeisun]

• ablation experiment: (1) const loss (2) tid loss
