Pseudocode Yes Algorithm 1 Rank Initialization; Algorithm 2 RIST: Riemann Submanifold Tracking; Algorithm 3 ROM: Riemann Optimization over Mk
Open Source Code No The paper does not contain any statement or link indicating that the source code for the described methodology is publicly available.
Open Datasets Yes Two collaborative filter datasets: the Jester-all dataset (Goldberg et al. 2001) and Movie-10M dataset (Herlocker et al. 1999) are used for the collaborative filtering.
Dataset Splits No The paper mentions training and test sets but does not explicitly describe a separate validation split, its size, or how it was used.
Hardware Specification Yes All comparison algorithms are implemented in Matlab and tested on a desktop computer with a 3.20 GHz CPU and 4.00 GB of memory.
Software Dependencies No The paper states "All comparison algorithms are implemented in Matlab" but does not specify a version number for Matlab or any other software dependencies.
Experiment Setup Yes The parameters ρ and η of RIST are set as 1.5 and 0.04, respectively. We set the rank parameter of these comparison methods as the ground-truth, namely, 15, 25 and 35. The parameters η of RIST is 0.05.
