What's the essential difference between ConvBert and LSRA? about convbert HOT 3 CLOSED

Is that LSRA combines multi-head attention and conv in a multi-branch manner, but ConvBert integrates conv into transformer blocks?
if the answer is yes. what are the pros and cons of the above two methods? Do you have experiments?

Thanks a lot!!!

Hi @yuanenming , Thanks for your interest.

LSRA is for machine translation and abstractive summarization. They are combining dynamic conv and multi-head attention in a two-branch manner.

ConvBERT is a pre-training based model that can be fine-tuned on downstream tasks like sentence classification. We also propose a novel span-based dynamic convolution operator and combine it with the self-attention to form the mixed-attention block.

Experiments comparing span-based dynamic conv and dynamic conv can be found in Section 4.3 Table 2 in our paper.

You can find that our span-based dynamic conv is better than dynamic conv in this pre-training based model setting. But it's hard to directly compare LSRA with ConvBERT.

Thank you for your timely reply!
I will close this issue.
