Unsupervised training data re-weighting for natural language understanding with local distribution approximation (2022.emnlp-industry)
Copied to clipboard
| Challenge: | a distribution mismatch between offline training and live data can cause biases . cyclic seasonality shifts, and changing pool of users can contribute to this problem . |
| Approach: | They propose an unsupervised approach to mitigate offline training data sampling bias . they propose a local distribution approximation in the pre-trained embedding space . |
| Outcome: | The proposed approach mitigates the offline training data sampling bias in multiple NLU tasks without additional annotation. |
Identifying and Resolving Annotation Changes for Natural Language Understanding (2021.naacl-industry)
Copied to clipboard
| Challenge: | Annotation conflict resolution is crucial for machine learning, says a new study . past work on annotation conflict resolution assumed data is collected at once . a a supervised neural model can resolve conflicts in data annotation but requires access to high-quality data . |
| Approach: | They propose an approach to resolve annotation conflicts in a real-world context using a German dialog system. |
| Outcome: | The proposed approach improves on a real-world dataset with 3.5M utterances in German. |
