Synthetic Survival Data Generation for Heart Failure Prognosis Using Deep Generative Models

Synthetic Survival Data Generation for Heart Failure Prognosis Using Deep Generative Models This collection features five public datasets of synthetically generated tabular data in heart failure patients, each created using a different generative model. The datasets include: TVAE.csv from a Tabular Variational Autoencoder (TVAE), ADSGAN.csv from an ADSGAN SurvivalGAN_df.csv from a SurvivalGAN. TabDDPM_df.csv, generated by a Tabular Denoising Diffusion Probabilistic Model (TabDDPM) NFlow_df.csv, created by a Normalizing Flow (NFlow) model. columns_class.yaml, specify discrete or continuous variables.
