We computed the Lyapunov spectrum and finite-time Lyapunov exponents of a data-driven model constructed using reservoir computing. This analysis was performed for two dynamics that exhibit a highly dimensionally unstable structure. We focused on the reconstruction of heterochaotic dynamics. which are characterized by the coexistence of different numbers of unstable dimensions. https://www.roneverhart.com/Asus-F1400EA-SB34-14-HD-1366x768-Laptop-Intel-Core-i3-1115G4-3-0-GHz-8GB-DDR4-256GB-SSD-Intel-UHD-Graphics-Windows-11-p9785/
