Improving Classroom Dialogue Act Recognition from Limited Labeled Data with Self-Supervised Contrastive Learning Classifiers (2023.findings-acl)
Copied to clipboard
| Challenge: | Recognizing classroom dialogue acts has significant promise for yielding insight into teaching, student learning, and classroom dynamics. |
| Approach: | They propose to use a contrastive learning-based self-supervised approach to improve classroom dialogue act recognition from limited labeled data by increasing the accuracy of dialogue act recognization and minimizing embedding distance between the same dialogue acts. |
| Outcome: | The proposed model outperforms baseline models when trained with limited examples per dialogue act and outperformed other few-shot models that require considerably more labeled data. |
