Sequence to Sequence Learning with Neural Networks（2014 Google Research）
However, the first few words in the source language are now very close to the first few words in the target language, so the problem’s minimal time lag is greatly reduced. Thus, backpropagation has an easier time “establishing communication” between the source sentence and the target sentence, which in turn results in substantially improved overall performance.
这篇文章基本上是重要的基石，上面这段的经验也被认为是大体正确的。“establishing communication” using SGD/ADAM etc do the BP and improve overall
