State Value Generation with Prompt Learning and Self-Training for Low-Resource Dialogue State Tracking

1 code implementation30 Jan 2024 Ming Gu, Yan Yang, Chengcai Chen, Zhou Yu

Experimental results on the MultiWOZ 2. 1 dataset show that our method which has only less than 1 billion parameters achieves state-of-the-art performance under the data ratio settings of 5%, 10%, and 25% when limited to models under 100 billion parameters.

Using Language Models For Knowledge Acquisition in Natural Language Reasoning Problems

no code implementations4 Apr 2023 Fangzhen Lin, Ziyi Shou, Chengcai Chen

For a natural language problem that requires some non-trivial reasoning to solve, there are at least two ways to do it using a large language model (LLM).

MOSS: End-to-End Dialog System Framework with Modular Supervision

1 code implementation12 Sep 2019 Weixin Liang, Youzhi Tian, Chengcai Chen, Zhou Yu

To utilize limited training data more efficiently, we propose Modular Supervision Network (MOSS), an encoder-decoder training framework that could incorporate supervision from various intermediate dialog system modules including natural language understanding, dialog state tracking, dialog policy learning, and natural language generation.
