How to get the best result?

[gk966988]

hi, thank you for your good work! It's helpful for me! But I run your code can only get a result of map=86.2% rank-1=94.6%. How to get the best result as you described map=94.2% Rank -1=95.8%？ and in “B1 + Harder Example Mining + searched reranking”， what does "B1" mean?

As shown in README, B1 means triplet loss + softmax + center loss. See more configurations in configs
