Strange attractor
Fractal geometric structure in phase space to which trajectories of a chaotic dynamical system converge. It characterizes the unpredictable but bounded long-term behavior of the system.
Lyapunov exponent
Quantitative measure of the rate of divergence of neighboring trajectories in a dynamical system, determining sensitivity to initial conditions. A positive exponent indicates chaotic behavior.
Poincaré map
Cross-section of phase space allowing the reduction of a continuous system analysis to a discrete system. It reveals the underlying structure of complex dynamic behavior.
Phase space reconstruction
Mathematical technique for reconstructing the dynamics of a system from a single observable time series. Based on Takens' theorem, it preserves the topological properties of the system.
Takens' theorem
Mathematical foundation guaranteeing that an attractor can be reconstructed from single observations using appropriate time delays. Essential for analyzing chaotic systems from empirical data.
Chaotic neural networks
Neural architectures integrating chaotic dynamics to improve the modeling capacity of complex systems. They explore the solution space more efficiently than traditional networks.
