Generating Synthetic Free-text Medical Records with Low Re-identification Risk using Masked Language Modeling (2025.naacl-srw)
Copied to clipboard
| Challenge: | Existing methods to generate medical records using Causal Language Modelling are limited due to privacy concerns. |
| Approach: | They propose a method for generating medical records using Masked Language Modelling using Causal language models. |
| Outcome: | The proposed method produces high-quality synthetic data with a re-identification risk of only 3.5% and a patient recall of 96%. |

| Challenge: | Existing approaches to enhance multilingual reasoning capabilities rely on costly multilingual training or employ prompting with external translation tools. |
| Approach: | They propose a training-free inference-time method to enhance multilingual reasoning capabilities via Representation Engineering without additional training data or tools. |
| Outcome: | The proposed method outperforms existing methods on four reasoning benchmarks in English and Thai and Swahili. |
