Pseudocode No The paper provides mathematical formulations for its model but does not include any pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any explicit statement or link indicating that its source code is publicly available.
Open Datasets Yes The dataset Advotago2 used in our experiments is obtained from a trust-based social network. ... 2http://www.trustlet.org/wiki/advogato dataset.
Dataset Splits Yes In total, we have conducted three groups of experiments with different percentages (80%, 60% and 40%) of the data for training. ... For model validation, we have conducted repeated random sub-sampling for 10 times in each experiment. Finally, each model is experimented with 300 times (3 different percentages 10 different initial matrices 10 times cross validations).
Hardware Specification No The paper does not provide specific hardware details (like GPU/CPU models or memory specifications) used for running its experiments.
Software Dependencies No The paper mentions using the gradient descent method and a real-valued Genetic Algorithm but does not specify any software dependencies with version numbers.
Experiment Setup Yes In all of the three approaches, we use the same gradient descent method for the matrix factorization process and set λ1 = λ2 = 0.01,γ = 0.1, H = 2 and l = 10.
