In the real world, you don't want AI to instantly flip from 90% confidence in one direction to 90% confidence in the other direction, because it would cause erratic behavior. What would be preferable is a large zone where it gives both labels .45 score. Then you can apply higher-level reasoning based on the possibility that the object could be either of those two labels (i.e. act on the possibility of the most dangerous or most beneficial scenario of the two).

But it doesn't instantly flip the decision in a way that can oscillate, it recognizes the similarity in specific positions where humans would also recognize it, and doesn't recognize anything in between (again the same as humans would). Isn't that the goal, to mimic how us humans do it? Imagine recognizing numbers 6 and 9, you want AI to recognize it with high certainty depending on what part of the digit is up, you don't want 45% certainty that it might be 9 or 6. Or am I missing something?

That doesn't make intuitive sense to me - I don't think humans have such a zone for (all) binary choices. An example that comes to my mind is the rotating Spinning Dancer Illusion[1] - I am 100% confident that she's spinning to the left, or 100% confident she's spinning to the right - there is no middle-ground where my brain tells me "it could be either direction".

Multistable/Bistable perception is not unique to Google Cloud vision - it afflicts humans too.

This. Maybe the AI needs to know somehow that it's the same image it saw a few seconds ago, but now presented at a different angle or the AI itself should look at an image at different angles, just to be sure, that is how humans sometimes look at pictures if they are confused. Something to contextualize every image wrt to what it recently saw and make the current decision a little less overconfident.

CV usually does look at images with different rotations, scaling, stretch. The point is that GCV doesn't get stuck on duck when the duck is upside down, it behaves the same way as a human classifier.

I'm looking forward to ReCAPTCHA asking "Click the images of things that are upside down."

You'd think, but the entire reason that softmax is so common in ml is because the artificial certainly is the preferred behavior.

In "real world", you expect AI to behave like human. Isn't that the definition?
