Pseudocode Yes Algorithm 1 MMHP Learning Algorithm
Open Source Code No The paper does not provide concrete access to source code for the methodology described.
Open Datasets Yes We simulate 100 training sequences and 100 testing sequences respectively. Each training sequence contains 2500 events... The dataset is collected from China Telecom, in Shanghai, China [Luo et al., 2014]
Dataset Splits No The paper does not explicitly describe a separate validation dataset split.
Hardware Specification No The paper does not provide specific hardware details (exact GPU/CPU models, processor types with speeds, memory amounts, or detailed computer specifications) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details (e.g., library or solver names with version numbers).
Experiment Setup Yes With the identified optimal configuration as λ1 = 0.2, λ2 = 0.004, M = 500, α = 100, we fix 3 parameters as their optimal values each time and alter the fourth parameter to train a different MMHP model. ...For all the methods, we set the length of the triggering kernel as 11520 minutes (8 days) and the sampling interval t as 20 minutes(M = 576).
