| Challenge: | Active Learning (AL) allows users to provide focused annotations to integrate human preferences and domain knowledge into machine learning models. |
| Approach: | They propose a counterfactual data augmentation approach inspired by Variation Theory to generate targeted variations along key conceptual dimensions. |
| Outcome: | The proposed approach achieves significantly higher performance when there are fewer annotated data, showing it can address the cold start problem in Active Learning. |
