Pseudocode Yes Algorithm 1 Learning Algorithm of Hawkes Processes
Open Source Code No The paper does not provide any statements or links indicating the availability of open-source code for the methodology described.
Open Datasets Yes MIMIC III Data. The MIMIC III data contain admission records of over 40, 000 patients in the Beth Israel Deaconess Medical Center between 2001 and 2012. ... Johnson, Alistair EW, Pollard, Tom J, Shen, Lu, Lehman, Li-wei H, Feng, Mengling, Ghassemi, Mohammad, Moody, Benjamin, Szolovits, Peter, Celi, Leo Anthony, and Mark, Roger G. Mimic-iii, a freely accessible critical care database. Scientific data, 3, 2016.
Dataset Splits No The paper mentions 'testing set' and 'training set' for all datasets but does not explicitly describe a separate 'validation' set or its split details.
Hardware Specification No The paper does not explicitly describe the hardware specifications (e.g., CPU, GPU models, memory) used to run the experiments.
Software Dependencies No The paper does not provide specific software names with version numbers required to reproduce the experiments.
Experiment Setup Yes In the following experiments, we use Gaussian basis functions: κm(t) = exp((t tm)2/σκ) with center tm and bandwidth σκ. ... Additionally, we set V = 10 4, γ = 1, and σs = 1 in our algorithm.
