Sequential Topic Selection Model with Latent Variable for Topic-Grounded Dialogue

no code implementations17 Oct 2022 Xiaofei Wen, Wei Wei, Xian-Ling Mao

To address the problem, in this paper we propose a novel approach, named Sequential Global Topic Attention (SGTA) to exploit topic transition over all conversations in a subtle way for better modeling post-to-response topic-transition and guiding the response generation to the current conversation.
