After the authors' rebuttal all reviewers believe the paper makes a significant enough contribution to be accepted to the conference. When there is a need to obtain large amounts of data for complex tasks such as VQA, bias in the labeling process is highly likely. Techniques that improve robustness to such biases can have a significant impact in these cases. The authors should incorporate the clarifications and results from the rebuttal into the paper and address the reviewers comments.
