论文笔记：Incorporating Copying Mechanism in Sequence-to-Sequence Learning-copynet

主要用途：

• certain segments in the input sequence are selectively replicated in the output sequence.
• COPYNET can nicely integrate the regular way of word generation in the decoder with the new copy-ing mechanism which can choose sub-sequences in the input sequence and put them at proper places in the output se-quence. 
• 即：可以有选择性的从源端复制句子到合适的目标端。

Encoder：

• 和别的encoder一样。

Decoder端：

read M and predict the target sequence,和之前的decoder有以下几点不同：

• Prediction:COP
