Improving Dialogue State Tracking with Turn-based Loss Function and Sequential Data Augmentation

1 code implementation • Findings (EMNLP) 2021 • Jarana Manotumruksa, Jeff Dalton, Edgar Meij, Emine Yilmaz

While state-of-the-art Dialogue State Tracking (DST) models show promising results, all of them rely on a traditional cross-entropy loss function during the training process, which may not be optimal for improving the joint goal accuracy.

MultiWOZ 2.4: A Multi-Domain Task-Oriented Dialogue Dataset with Essential Annotation Corrections to Improve State Tracking Evaluation

1 code implementation • SIGDIAL (ACL) 2022 • Fanghua Ye, Jarana Manotumruksa, Emine Yilmaz

The annotations in the training set remain unchanged (same as MultiWOZ 2. 1) to elicit robust and noise-resilient model training.
