Pseudocode Yes Algorithm 1 : Embedding Generation Process of SNEA.
Open Source Code No The paper provides links to the code for baseline methods (Si NE, SIDE, SGCN, Si GAT) in footnotes, but there is no explicit statement or link indicating that the source code for the proposed SNEA framework is available.
Open Datasets Yes We conduct experiments on four real-world signed networks to evaluate the effectiveness the proposed framework: Bitcoin-Alpha1, Bitcoin-OTC2, Epinions3 and Slashdot4. 1http://www.btc-alpha.com 2http://www.bitcoin-otc.com 3http://www.epinions.com 4http://www.slashdot.com
Dataset Splits No For signed link prediction task, we randomly select 80% links as training set to learn the node embeddings and utilize the remaining links as test set to evaluate the performance.
Hardware Specification No The paper does not provide any specific details regarding the hardware (e.g., GPU models, CPU types) used for running the experiments.
Software Dependencies No The paper mentions using 'Xavier initialization' and 'Ada Grad' for training, but does not specify any software dependencies with version numbers (e.g., programming languages, libraries, or frameworks with their versions).
Experiment Setup Yes For a fair comparison, we set the final embedding dimension as 64 for all the methods. ... For SNEA, we set λ as 4. ... we use final node embeddings (i.e., U) of TSVD as the initial embeddings of SNEA model.
