You say that “if your model is classifying based in features that change with resampling, it’s not trustworthy.”
I say that choice of resampling algorithm is what determines whether a model can learn the rule “zebras can be recognized by their uniform-width stripes” or not; as a bad resample will result in non-uniform-width stripes (or, at sufficiently small scales, loss of stripes!)

- derefr 4y agoA zebra having stripes that alternate between 5 black pixels, and 4 black pixels + 1 dark-grey pixel, isn’t actually a visible change to the human eye. But it’s visible to the model.
- alanbernstein 4y agoI'm not saying your general argument is wrong, but... zebra stripes are not made out of pixels. A model that requires a photograph of a zebra to align with the camera's sensor grid also has bigger problems.
