Reproducibility Variable Result LLM Response
Research Type Experimental We empirically illustrate our metric with an example of rotation dynamics in a unit disk in a complex plane, and evaluate the performance with real-world time-series data.

Pseudocode No The paper describes methods mathematically and in prose, but does not include any explicit pseudocode or algorithm blocks.
Open Source Code Yes The Matlab code is available at https://github.com/keisuke198619/metric NLDS
Open Datasets Yes We used the UCR time series classification archive as open-source real-world data [5].
Dataset Splits Yes For clear visualization, we randomly selected 20 sequences for each label from validation data... We used 40 sequences for each label and computed averaged 10-fold cross-validation error (over 10 random trials).
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments.
Software Dependencies No The paper mentions 'Matlab code' but does not specify the version of Matlab or any other software dependencies with version numbers.
Experiment Setup Yes For the Gaussian kernel, the kernel width was set as the median of the distances from data. ... We used k-nearest neighbor classifier (k = 3) for simplicity.
