Pseudocode Yes Algorithm 1: Variational Inference with Extremals.
Open Source Code Yes Our implementation is based on Py Torch, and code to replicate our experiments are available from https://github.com/Zidi Xiu/VIE/.
Open Datasets Yes To this end, we synthesize a semi-synthetic dataset based on the Framingham study (Mitchell et al. 2010), a long-term cardiovascular survival cohort study... (ii) In P (O Brien et al. 2020): An in-patient data from DUHS... (iii) SEER (Ries et al. 2007): A public dataset studying cancer survival among adults curated by the U.S. Surveillance, Epidemiology, and End Results (SEER) Program...
Dataset Splits Yes Datasets have been randomly split into training, validation, and testing datasets with ratio 6:2:2.
Hardware Specification No The paper does not provide specific details about the hardware used for experiments, such as CPU or GPU models, memory, or cloud instance types.
Software Dependencies No The paper states, "Our implementation is based on Py Torch," but does not specify its version number or any other software dependencies with their respective versions.
Experiment Setup Yes Datasets have been randomly split into training, validation, and testing datasets with ratio 6:2:2... In simulation studies, we repeat simulation ten times to obtain empirical AUC and AUPRC confidence intervals. For real world datasets, we applied bootstrapping to estimate the confidence intervals...
