HLATR in this project #1

Closed SiyuanHuangSJTU closed 2 months ago

SiyuanHuangSJTU commented 2 months ago

Hello, thanks for your great work!

I have a little question about the code implementation. In your code repo, there is a HLATR reranker (i.e. class HLATR_reranker in src/t5_model), which i suppose is adopted from [1]. However, in your paper, i didn't find any information mentioned HLATR.

I wonder what's the function of HLATR here. Can you provide a brief extra information about it? That will help a lot. Thanks.

Thanks for your interest in our research :)

The HLATR mentioned in the code is indeed the work you are referring to. While MGFiD performs passage re-ranking as a multi-task, applying the HLATR was one of the variants we explored. However, we decided not to include it in the final version.
