“A novel approach to neural machine translation” by Facebook team shows a State-of-the-art results: https://code.facebook.com/posts/1978007565818999/a-novel-approach-to-neural-machine-translation/
This approach is an alternative architecture for neural machine translation that opens up new possibilities for other text processing tasks. For example, multi-hop attention in dialogue systems allows neural networks to focus on distinct parts of the conversation, such as two separate facts, and to tie them together in order to better respond to complex questions.
