### Chaotic Time Series Dataset
Multivariate time series from chaotic dynamical systems.
+ Each multivariate time series is a drawn from one chaotic dynamical system over an extended duration, making this dataset suitable for long-horizon forecasting tasks.
+ There are 4 million total multivariate observations, grouped into 135 systems and three granularities
+ The subdirectories `coarse`, `medium`, and `fine` each contain 135 `.csv` files, each of which contains a single multivariate time series of length 10,000
+ The number of channels varies depending on the specific dynamical system.
+ The time series are stationary due to the ergodic property of chaotic systems.
