CUNI System for the WMT18 Multimodal Translation Task
This is an incremental improvement for machine translation researchers, focusing on enhancing multimodal translation systems.
The paper tackled multimodal translation by applying a self-attentive network instead of recurrent neural networks and incorporating visual features through two methods, resulting in significant improvements over baselines.
We present our submission to the WMT18 Multimodal Translation Task. The main feature of our submission is applying a self-attentive network instead of a recurrent neural network. We evaluate two methods of incorporating the visual features in the model: first, we include the image representation as another input to the network; second, we train the model to predict the visual features and use it as an auxiliary objective. For our submission, we acquired both textual and multimodal additional data. Both of the proposed methods yield significant improvements over recurrent networks and self-attentive textual baselines.
