Reproducibility Variable Result LLM Response
Research Type Experimental Our numerical experiments demonstrated that our methods can stably estimate the model parameters, even in high dimensions or when there are a small number of samples.

Pseudocode No The paper describes methods through mathematical formulations and text but does not include any explicit pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any explicit statements about releasing source code for the described methodology or a link to a code repository.
Open Datasets Yes Next, we applied GSPCCA and PCCA to meteorological data, using the Global Summary of the Day (GSOD) provided by the National Climatic Data Center (NCDC) on its website.
Dataset Splits No The paper mentions 'five-fold cross validation (CV)' as a model selection technique, but does not explicitly provide the training, validation, or test dataset splits needed to reproduce the main experiments.
Hardware Specification No The paper does not provide any specific hardware details such as GPU/CPU models, memory, or cloud instance types used for running the experiments.
Software Dependencies No The paper does not specify any software dependencies with version numbers, such as programming languages, libraries, or specialized solvers.
Experiment Setup Yes In our experiments, we set a0, b0 = 10 14, νm 0 = dm, Km 0 = 10 14 Idm. The ARD prior drives unnecessary components to zero, so we can estimate the dimensions of the latent variables by choosing sufficiently large dz, or by first choosing a small dz and then gradually increasing it according to the output projection matrices. We refer to this model as Bayesian PCCA (BPCCA).
