Reproducibility Variable Result LLM Response
Research Type Experimental Finally, the empirical experiments on several real-world benchmark datasets demonstrate that our L2SC model can effectively improve the clustering performance when comparing with other state-of-the-art spectral clustering algorithms.

Pseudocode Yes Algorithm 1 Lifelong Spectral Clustering (L2SC) Model
Open Source Code No The paper does not contain any statements about making source code publicly available or links to a code repository.
Open Datasets Yes We thus use two datasets in this paper: Web KB41 with 2500 dimensions and Reuters2 with 6370 dimensions, respectively. ... For the Cluster-inconsistent dataset, we also adopt 20News Groups3 dataset with 3000 dimensions by following (Zhang et al. 2018)...

Dataset Splits No The paper mentions "10 random repetitions" for averaging results and describes how categories are selected for tasks in the 20News Groups dataset (e.g., "1-th and 3-th tasks are set as 3 categories, and the 2-th and 4-th tasks are set as 4 categories"), but it does not provide specific train/validation/test dataset split percentages or absolute sample counts for any of the datasets.
Hardware Specification Yes We perform all the experiments on the computer with Intel i7 CPU, 8G RAM.
Software Dependencies No The paper states "We implement all the models in MATLAB," but it does not provide specific version numbers for MATLAB or any other software dependencies, libraries, or solvers.
Experiment Setup Yes all the used parameters of the models are tuned in {10^3 i}^10_{i=1} {10^2 i}^10_{i=2} {10^1 i}^10_{i=2} {2 i}^10_{i=1} {40 i}^20_{i=1}. and appropriate parameters can make the generalization performance better, e.g., λ = 100 for Web KB4 dataset.
