"description_complex": "A continuous-time stochastic differential equation describing a mean-reverting Gaussian process driven by Brownian motion. The dynamics are inherently random rather than deterministic, with trajectories influenced by the noise term σ dW_t. The process has a stationary Gaussian distribution and well-defined statistical properties, but individual sample paths cannot be predicted exactly in the long term.",
