For the image part, there is already a rapidly growing research on evaluating the robustness of deep learning models (Fawzi, Moosavi Dezfooli, and Frossard 2017;  Table 3 : MUTAN without Attention model evaluation results on BQD and <cite>VQA dataset</cite> (<cite>Antol et al. 2015</cite>) . "-" indicates the results are not available, "-std" means the accuracy of VQA model evaluated on the complete testing set of BQD and <cite>VQA dataset</cite> and "-dev" means the accuracy of VQA model evaluated on the partial testing set of BQD and <cite>VQA dataset</cite>.
