Is it possible to narrow in on a hash using gradient descent? You can correlate distance between inputs to distance between hashes somehow?

Replying to my own question since I can’t edit anymore: it turns out “perceptual hashing,” which I didn’t know much about, has exactly this property, that small changes in the input result in small changes in the output.
