For instance, the caption two elephants standing next to each other in a grass field is associated with the decoy a herd of giraffes standing next to each other in a dirt field (errors: herd, giraffe, dirt) or with animals are gathering next to each other in a dirt field (error: dirt; infelicities: animals and gathering, which are both pragmatically odd).
the IC model tends to be biased toward the foil captions, on which it achieves an accuracy of 45.44%, higher than the VQA models.
