New method speeds up analysis of high-dimensional dynamical systems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel, computationally efficient method for analyzing high-dimensional dynamical systems, specifically focusing on Ornstein-Uhlenbeck processes. This new approach utilizes an orthogonal factor loading matrix to bypass complex posterior covariance inversions, leading to significant speedups without sacrificing accuracy. The method has demonstrated superior performance in simulations and has been successfully applied to real-world geodetic data for estimating slow slip events, offering potential for improved geological hazard quantification.

    Fast data inversion for high-dimensional Ornstein-Uhlenbeck processes from noisy measurements

    arXiv:2501.01324v4 Announce Type: replace-cross Abstract: In this work, we develop a scalable approach for a flexible latent factor model for high-dimensional dynamical systems. Each latent factor process has its own correlation and variance parameters, and the orthogonal factor …
