abstract = {Electronic Health Records (EHR) include heteroge- neous clinical information, which includes diagnoses, medications, procedures, and laboratory measurements that are highly inter- dependent and incomplete. The conventional machine learning models normally consider these variables as independent features, which restricts them in capturing complex clinical relations and uncertainty of the real-world healthcare data.
We suggest a Variational Graph Neural Network (VGNN) framework to make predictive models of neurodegenerative dis- eases based on EHR data in this paper. Our model models clinical events as a graph and trains their interactions by attention-based message passing functions. We develop variational regularization, a method that learns a latent embedding distribution subject to KL-divergence to predict with uncertainty, to enhance robustness in the presence of noisy, sparse and incomplete medical records. The suggested framework presents well-organized patient representations to accurately predict diseases and is a base of smart clinical decision support systems.},
