Pseudocode Yes Algorithm 1 Multiway clustering based on tensor block models
Open Source Code Yes Our software is available at https://cran.r-project.org/web/packages/tensorsparse.
Open Datasets Yes The first dataset is a real-valued tensor, consisting of approximate 1 million expression values from 13 brain tissues, 193 individuals, and 362 genes [4]. The second dataset we consider is the Nations data [2].
Dataset Splits No The paper mentions conducting simulation studies and applying the method to real datasets but does not provide specific details on train/validation/test dataset splits, percentages, or sample counts.
Hardware Specification No The paper does not provide specific hardware details (e.g., CPU, GPU models, memory amounts, or detailed computer specifications) used for running its experiments.
Software Dependencies No The paper mentions that their software is an R package available on CRAN, but it does not specify version numbers for R or any other software dependencies.
Experiment Setup Yes Unless otherwise stated, we generate Gaussian tensors under the block model (1). The block means are generated from i.i.d. Uniform[-3,3]. The entries in the noise tensor E are generated from i.i.d. N(0, σ2). In each simulation study, we report the summary statistics across nsim = 50 replications. We set σ = 3 and consider tensors of order 3 and order 4.
