| Challenge: | Current models for survival analysis are limited in scope and require a large amount of data and expert annotations for training. |
| Approach: | They propose to use BERT-based hidden layer representations of clinical texts as covariates for proportional hazards models to predict patient survival outcomes. |
| Outcome: | The proposed method outperforms the baseline model by 5.7% across C-index and time-dependent AUC. |
