Pseudocode Yes Algorithm 1 Projected Gradient Descent Algorithm for Parameter Estimation
Open Source Code No The paper does not provide any specific links or explicit statements about the availability of source code for the described methodology.
Open Datasets Yes The Lazega Lawyers dataset records multiple connection re lationships in a Northeastern US corporate law firm (Lazega et al., 2001). ... Banerjee et al. (2013) provided multiple social networks in villages in rural southern Karnataka, India.
Dataset Splits No The paper specifies removing 20% entries for link prediction testing, but it does not provide explicit train/validation/test dataset splits needed to reproduce the model training (e.g., percentages or sample counts for validation sets for hyperparameter tuning).
Hardware Specification No The paper does not provide specific hardware details (e.g., exact GPU/CPU models, memory amounts) used for running its experiments.
Software Dependencies No The paper does not list specific software dependencies with version numbers (e.g., programming languages, libraries, or solvers with their versions).
Experiment Setup Yes We set n = 400, R = 100, and k = 2. ... initial estimates: U0, {α0 }r=1; step sizes ηu, ηα, ηλ; number of iterations T ... The step sizes ηα, ηλ are chosen to be small and fixed, and ηu is proportional to R −10 .
