Before revision:  In this work, we explore to reuse the representations from different encoder layers for layer-wise cross-view decoding , that is, different views of the source sequences are presented to different decoder layers . We investigate multiple , representative strategies for cross-view coding, of which the granularity consistent attention (GCA) strategy proves the most efficient and effective in the experiments on  neural machine translation task . Especially, GCA surpasses the previous state-of-the-art architecture on three machine translation datasets.
