Questions about the inference stage

[qjyyyy]

Thank you for sharing such a great job!

You concatenated the latent factors of text and video subspace to calculate similarity through MLP, which means that during the testing phase, we also need to perform this operation on the query and every candidate. Compared to the cosine similarity used in many previous methods, this does not seem to be an efficient approach. I would like to hear your opinion on this issue.
