  abstract  = {In this year, we participated in four translation subtasks at WAT 2017.
	Our model structure is quite simple but we used it with well-tuned
	hyper-parameters, leading to a significant improvement compared to the previous
	state-of-the-art system.
	We also tried to make use of the unreliable part of the provided parallel
	corpus by back-translating and making a synthetic corpus.
	Our submitted system achieved the new state-of-the-art performance in terms of
	the BLEU score, as well as human evaluation.},
