HSCJN: A Holistic Semantic Constraint Joint Network for Diverse Response Generation

no code implementations1 Dec 2019 Yiru Wang, Pengda Si, Zeyang Lei, Guangxu Xun, Yujiu Yang

The sequence-to-sequence (Seq2Seq) model generates target words iteratively given the previously observed words during decoding process, which results in the loss of the holistic semantics in the target response and the complete semantic relationship between responses and dialogue histories.
