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.
