A New Dialogue Response Generation Agent for Large Language Models by Asking Questions to Detect User's Intentions

no code implementations5 Oct 2023 Siwei Wu, Xiangqing Shen, Rui Xia

Firstly, EDIT generates open questions related to the dialogue context as the potential user's intention; Then, EDIT answers those questions by interacting with LLMs and searching in domain-specific knowledge bases respectively, and use LLMs to choose the proper answers to questions as extra knowledge; Finally, EDIT enhances response generation by explicitly integrating those extra knowledge.

VLUCI: Variational Learning of Unobserved Confounders for Counterfactual Inference

no code implementations2 Aug 2023 Yonghe Zhao, Qiang Huang, Siwei Wu, Yun Peng, Huiyan Sun

By disentangling observed and unobserved confounders, VLUCI constructs a doubly variational inference model to approximate the distribution of unobserved confounders, which are used for inferring more accurate counterfactual outcomes.
