  Abstract: The vanilla attention-based neural machine translation has achieved promising performance because of its capability in leveraging varying-length source annotations. However, this model still suffers from failures in long sentence translation, for its incapability in capturing long-term dependencies. In this paper, we propose a novel recurrent neural machine translation (RNMT), which not only preserves the ability to model varying-length source annotations but also better captures long-term dependencies. Instead of the conventional attention mechanism, RNMT employs a recurrent neural network to extract the context vector, where the target-side previous hidden state serves as its initial state, and the source annotations serve as its inputs. We refer to this new component as contexter. As the encoder, contexter and decoder in our model are all derivable recurrent neural networks, our model can still be trained end-to-end on large-scale corpus via stochastic algorithms. Experiments on Chinese-English translation tasks demonstrate the superiority of our model to attention-based neural machine translation, especially on long sentences. Besides, further analysis of the contexter revels that our model can implicitly reflect the alignment to source sentence.
