Does Collaborative Human-LM Dialogue Generation Help Information Extraction from Human Dialogues?

no code implementations13 Jul 2023 Bo-Ru Lu, Nikita Haduong, Chia-Hsuan Lee, Zeqiu Wu, Hao Cheng, Paul Koester, Jean Utke, Tao Yu, Noah A. Smith, Mari Ostendorf

The capabilities of pretrained language models have opened opportunities to explore new application areas, but applications involving human-human interaction are limited by the fact that most data is protected from public release for privacy reasons.

In-Context Learning for Few-Shot Dialogue State Tracking

1 code implementation16 Mar 2022 Yushi Hu, Chia-Hsuan Lee, Tianbao Xie, Tao Yu, Noah A. Smith, Mari Ostendorf

In this work, we propose an in-context learning (ICL) framework for zero-shot and few-shot learning DST, where a large pre-trained language model (LM) takes a test instance and a few exemplars as input, and directly decodes the dialogue state without any parameter updates.

Cross-Lingual Transfer Learning for Question Answering

no code implementations13 Jul 2019 Chia-Hsuan Lee, Hung-Yi Lee

In this paper, we explore the problem of cross-lingual transfer learning for QA, where a source language task with plentiful annotations is utilized to improve the performance of a QA model on a target language task with limited available annotations.
