Evaluating RepCONC on different datasets in a zero-shot fashion about repconc

[jingtaozhan]

Hi Nandan,

Thanks for your interest in our work. I planned to update you on this repo after I released the training code :)

BEIR is a very fascinating benchmark, and it will be great to evaluate RepCONC on it. I will try testing RepCONC on one of the selected datasets (e.g., TREC-COVID) and then share the code. I will update here when the code is ready.

Best,
Jingtao

Hi @jingtaozhan,

Thank you so much! I look forward to the code when it's ready!

Hi @jingtaozhan,

I understand that you will be busy with other work with higher priorities.
Would it be possible for you to provide an approximate timeline for this? If possible.

Thanks!

Hi @NThakur20

I'm currently working on it and it is almost done. The repo will be updated today. RepCONC will utilize the JPQ package to perform zero-shot retrieval for BEIR. Here is how I evaluate JPQ on BEIR.

I write code by following the model examples in BEIR repo. So I think both JPQ and RepCONC can be added to the BEIR examples. What do you think?

Awesome, thank you so much @jingtaozhan!

Yes, I believe both will be interesting to evaluate, I'm currently working on a paper where we are evaluating several memory compression strategies. I can add these examples to the BEIR examples folder as well :)

Kind Regards,

The code is released now. Happy to help if you have any other questions.

I do think it's very meaningful to include JPQ and RepCONC in BEIR examples. They follow a different paradigm, joint optimization with compact index, compared with many existing DR models. It wouldn't be hard to add them since the code is ready. I can open a PR if you think is OK.

Thanks @jingtaozhan, for providing the scores and the script soon.

I think it will be definitely interesting to add the models to the repository. I would be happy if you can open a PR in the repository.

Thanks,

Hi @NThakur20

I update the code so that it is now very easy to apply RepCONC to different dense retrieval models (Pull Request). Thought you might be interested.

Hi @jingtaozhan,

Thank you for the PR and apologies for the delay. Will have a look.

Meanwhile, in a recent preprint of ours, we found our work on GPL (https://aclanthology.org/2022.naacl-main.168/) useful to help improve zero-shot JPQ performance. We experimented with JPQ on all BEIR datasets (with TAS-B as backbone instead of STAR). GPL which involves cross-encoder distillation with MarginMSE loss function helped improve JPQ models across all BEIR datasets and even outperformed the original uncompressed TAS-B model. For more details, you can have a look below. Would like to get some feedback :)
