UniHPF : Universal Healthcare Predictive Framework with Zero Domain Knowledge
share
Despite the abundance of Electronic Healthcare Records (EHR), its heterogeneity restricts the utilization of medical data in building predictive models. To address this challenge, we propose Universal Healthcare Predictive Framework (UniHPF), which requires no medical domain knowledge and minimal pre-processing for multiple prediction tasks. Experimental results demonstrate that UniHPF is capable of building large-scale EHR models that can process any form of medical data from distinct EHR systems. Our framework significantly outperforms baseline models in multi-source learning tasks, including transfer and pooled learning, while also showing comparable results when trained on a single medical dataset. To empirically demonstrate the efficacy of our work, we conducted extensive experiments using various datasets, model structures, and tasks. We believe that our findings can provide helpful insights for further research on the multi-source learning of EHRs.
