But only with context right? It is completely ambiguous if the character is 6 or 9 without some other clue, like which way up the paper is, or from the 4 next to it (if you assume that an arbitrary rotation may have occurred).
It is just a sign to me that doing some rotations as data augmentation is not good enough. Rotation invariance needs to be built into the architecture of the network (like translation invariance sort of gets in via max pooling).
I think it should be giving a 50/50 classification of duck and rabbit at all rotations if it was working as expected.

This would likely give incorrect or worse results when, eg, classifying ducks and rabbits in wildlife photos — animals come in orientations, and you’ll do a better job classifying them in practice if you respect that. It’s also not the case that a human would classify it 50/50 in all rotations — it certainly looks more or less like one or the other as you rotate it. Humans are even program,Ed for that compromise: we see faces in one orientation much better than rotated 180 degrees.
