Pseudocode No The paper describes the inference procedure in narrative text but does not provide a formal pseudocode or algorithm block.
Open Source Code Yes Source code is available at https://github.com/catniplab/tree_structured_rslds
Open Datasets Yes Finally, we apply the proposed method on the data from Graf et al. (2011).
Dataset Splits No The paper specifies training and testing splits for synthetic data, but no explicit validation split is mentioned for any experiment.
Hardware Specification No No specific hardware details (e.g., GPU/CPU models, memory specifications) are provided in the paper for running experiments.
Software Dependencies No The paper does not list specific version numbers for software dependencies or libraries used (e.g., 'Python 3.8', 'PyTorch 1.9').
Experiment Setup Yes We set the number of leaf nodes to be 4 and ran Gibbs for 1,000 samples; the last 50 samples were kept and we choose the sample that produced the highest log likelihood to produce Fig. 2 where the vector fields were produced using the mode of the conditional posteriors of the dynamics.
