Get uncertainty

[mees]

Hi,
is it possible to compute some kind of uncertainty about the answer given for a comprehension? Like for example if you query with an ambiguous expression or you query for classes not present on the image?

Probably not with current contrastive ranking loss. You could try replacing it with binary cross-entropy, which could output a [0, 1) score. I would imagine an ambiguous expression would return all boxes with lower than 0.5
