Hello. Thank you for your great work!

I have a few questions regarding CoCondenser fine tuning. First, When training 1st fine tuning and 2nd fine tuning on Ms-marco dataset, can you know the number of negative samples and hard negative samples?

The second, What are the criteria for selecting hard negative samples? For example, when the rank of positive document is 5th, hard negative samples are 1st to 4th.
