Furthermore, we observe an interesting phenomenon that humans can easily achieve a high entity F1 score with a low BLEU score.
less related to dialog systems, but related to our work, are the memory based decoders and the nonrecurrent generative models: 1) Mem2Seq query generation phase used to access our memories can be seen as the memory controller used in Memory Augmented Neural Networks (MANN) (Graves et al., 2014(Graves et al., , 2016.
