Efficient Semi-supervised Consistency Training for Natural Language Understanding (2022.naacl-industry)
Copied to clipboard
| Challenge: | Manually labeled training data is expensive, noisy, and often scarce . semi-supervised learning methods can be used to improve model performance . |
| Approach: | They explore different methods for consistency training on unlabeled data . they use human paraphrasing, back-translation, and dropout to augment unlabed data. |
| Outcome: | The proposed methods outperform purely supervised learning on unlabeled data. |
Influence Scores at Scale for Efficient Language Data Sampling (2023.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have shown that ML models can be fine-tuned on as much data as possible without degradation in performance metrics. |
| Approach: | They evaluate the applicability of influence scores in language classification tasks by random sampling and stress-testing one of the scores. |
| Outcome: | The proposed model can be fine-tuned on 50% of the original data without degradation in performance metrics. |
