Nlphut'S Participation At Wat2021

This paper provides the description of shared tasks to the WAT 2021 by our team "NLPHut". We have participated in the English -> Hindi Multimodal translation task, English -> Malayalam Multimodal translation task, and Indic Multilingual translation task. We have used the state-of-the-art Transformer model with language tags in different settings for the translation task and proposed a novel "region-specific" caption generation approach using a combination of image CNN and LSTM for the Hindi and Malayalam image captioning. Our submission tops in English -> Malayalam Multimodal translation task (text-only translation, and Malayalam caption), and ranks second-best in English -> Hindi Multimodal translation task (text-only translation, and Hindi caption). Our submissions have also performed well in the Indic Multilingual translation tasks.
