| 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...
