Synthesize High-dimensional Longitudinal Electronic Health Records via Hierarchical Autoregressive Language Model

1 code implementation4 Apr 2023 Brandon Theodorou, Cao Xiao, Jimeng Sun

In this paper, we propose Hierarchical Autoregressive Language mOdel (HALO) for generating longitudinal high-dimensional EHR, which preserve the statistical properties of real EHR and can be used to train accurate ML models without privacy concerns.
