Adversarial reconstruction for Multi-modal Machine Translation
Table 4: Ablation study of Q-WAAE model
['[BOLD] Test sets', '[BOLD] COCO-ambiguous  [BOLD] BLEU', '[BOLD] COCO-ambiguous  [BOLD] METEOR']
To understand the success of Q-WAAE on the ambiguous COCO data-set, we perform an ablation study of the model. We first discard the adversarial discriminator so that we only train the reconstruction module with the MSE loss (+ G). We also discard the use of the features v in the translation model for both the ablated model and Q-WAAE (no v).
