IMO, your edits begin to uncover a statistical question, but maybe didn't go far enough to convince the reviewers. If all you really/eventually/now want to ask is "Can a filter size of 8 suffice for SSIM?" (or similar, like "what's the minimal reasonable", or "what effect does a small size", etc.) then ask that without any reference to tensorflow (or maybe some minimal such reference, for the default there).

(I don't actually know much about SSIM, so grain of salt. And I do worry whether there's an objectively correct answer to some of the phrasings I listed.)

Yes @kjetilbhalvorsen, I have seen the paper. It's not the other way round.

BTW @kjetilbhalvorsen, may I ask you whether "sufficient dimension reduction" is associated with sufficiency or sufficient statistic? I am not familiar with the term and I am not seeing how it's related to the latter.

@User1865345 I don't know, and en.wikipedia.org/wiki/Sufficient_dimension_reduction says it is related to sufficiency, but I cannot see how ...

I see @kjetil; thanks.

@User1865345 I had never heard of SDR. Thanks for mentioning it.

@Galen me neither. If you are interested, this seemed to be an authoritative reference: routledge.com/…

Nice! Thank you.
