Reproducibility Variable Result LLM Response
Research Type Experimental Experimental results on synthetic datasets show that MISC can find different interesting clusterings from the sought independent subspaces, and it also outperforms other related and competitive approaches on real-world datasets.

Pseudocode Yes Algorithm 1 MISC: Multiple Independent Subspace Clusterings
Open Source Code Yes The code for MISC is available at http://mlda.swu.edu.cn/codes.php?name=MISC.
Open Datasets Yes The second and third synthetic datasets are collected from the Fundamental Clustering Problem Suite (FCPS)2. http://www.uni-marburg.de/fb12/datenbionik/downloads/FCPS
Dataset Splits No The paper describes the datasets used but does not provide specific details on training, validation, or test splits (e.g., percentages, sample counts, or explicit references to predefined splits).
Hardware Specification No The paper does not provide specific hardware details (e.g., exact GPU/CPU models, processor types, or memory amounts) used for running its experiments.
Software Dependencies No The paper does not provide specific ancillary software details, such as library or solver names with version numbers, needed to replicate the experiment.
Experiment Setup Yes We choose the Gaussian heat kernel as the kernel function and the kernel width is set to the standard variance σ = sqrt(Pn i=1 X i X 2 /n). Following the set of GNMF in (Cai et al. 2011), we use 0-1 weighting and adopt the neighborhood size ϵ = 5 to compute the graph adjacency matrix P, and then set λ = 10 in Eq. (8). We also set the number of subspaces as 2 and the number of clusters as that of true labels of CMUface and Web KB datasets, respectively.
