SSMBA: Self-Supervised Manifold Based Data Augmentation for Improving Out-of-Domain Robustness (2020.emnlp-main)
Copied to clipboard
| Challenge: | Data augmentation is a common method used to improve out-of-domain (OOD) generalization. |
| Approach: | They propose a data augmentation method that uses corruption and reconstruction functions to move randomly on a manifold to generate training examples. |
| Outcome: | The proposed method outperforms existing methods and baseline models on both in-domain and OOD data and achieves gains of 0.8% on OOD Amazon reviews, 1.8% accuracy on OOO MNLI, and 1.4 BLEU on in- domain IWSLT14 German-English. |
