Training Text-to-Text Transformers with Privacy Guarantees (2022.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in NLP often stem from large transformer-based pre-trained models. |
| Approach: | They propose differentially private (DP) training as a potential mitigation for models that can memorize parts of training data. |
| Outcome: | The proposed model can memorize parts of training data and mitigate memorization concerns. |

| Challenge: | Existing approaches to generate differentially private text using large language models are classified into several categories. |
| Approach: | They propose a private prediction framework that generates differentially private synthetic text using large language models via private prediction. |
| Outcome: | The proposed approach generates high-quality synthetic data points at reasonable privacy levels while protecting the privacy of users who contributed to the dataset. |
