Pseudocode Yes Algorithm 1, which we denote by SGL, summarizes the implementation of the structured graph learning via Laplacian spectral constraints.
Open Source Code Yes An R package containing code for all the experimental results is available at https://cran.r-project. org/package=spectral Graph Topology. [...] An R package containing the code for all the simulations is made available as open source repository.
Open Datasets Yes We apply SGL to learn similarity graphs from a real categorical animal dataset [65] with binary entries [...] Herein, animals data set [65, 67] is taken into consideration to learn weighted graphs. [...] We consider the RNA-Seq Cancer Genome Atlas Research Network [66] data set available at the UC-Irvine Machine Learning Database [68].
Dataset Splits No The paper does not provide specific details about training, validation, or test dataset splits (e.g., percentages, sample counts, or methods for creating them).
Hardware Specification No The paper does not specify any hardware details (e.g., CPU, GPU models, or memory) used for running the experiments.
Software Dependencies No The paper mentions an 'R package' for code but does not specify version numbers for R or any specific software libraries/dependencies used in the implementation.
Experiment Setup Yes Algorithm 1 Input: SCM S, k, c1, c2, β [...] The input for all the algorithms is the sample covariance matrix plus an identity matrix scaled by 1/3 (see [26]). [...] SGL with k = 1, and (d) SGL with k = 5.
