I'm not sure I followed this comment as I understood your earlier comment about disliking mandatory cites as leaning towards allowing more author discretion? But I understood this comment like an argument for less author discretion?
100
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
However, if you cite something that you think is actively bad/wrong I think that it is perfectly fine to argue that point in the related work/discussion section, or perhaps in an extended part of it in the supplementary/appendix.
010
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
Ah, I see. Perhaps I then misunderstood your comment about being opinionated about what is worth citing. As I mentioned, my comment wasn't about this specific case as it is from my understanding quite a bit more complex than what was available on OpenReview.
210
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
Just to be extra clear, my comment was not (and is not) a comment about this specific case. My comment was about whether it is ok in general to not cite relevant work because an author dislikes it and therefore doesn't think it is worth citing. Of course relevance is to some degree subjective.
100
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
Indeed, as I mentioned it is not black and white and there is of course a cutoff. But not citing relevant papers because of personal taste is the wrong direction imo.
220
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
Of course there is a grayscale, but I don't think ones personal opinion about a work's worth should be given much weight when deciding whether a citation is warranted or not. (note these are comments about citation norms in general and not this case in particular)
110
Christian A. Naesseth @canaesseth.bsky.social · 13/04/2025
In general, I believe in stronger norms as weaker would allow for even more abuse and gaming than whatever our current norms are. If the work is relevant, it should be cited. If the work is highly relevant, it should be cited and discussed. In the discussion you can ofc give your opinion about it.

This is really interesting! Learning the posterior probability path p(x0 | xt) rather than only the mean is something we suggested in Variational Flow Matching as well, but for a different reason (generating discrete data). Very cool that it can also be used for faster generation.

One way to get (almost) both is to penalise the curvature of the learned velocity field of diffusion/bridge explicitly. We do this in our paper on Neural Flow Diffusion Models. There are also bridge variants in the paper. arxiv.org/abs/2404.12940
