Predictability of Observables of Dynamical Systems
Xinyu Liu, Dongbin Xiu
We study the evolution of observables of dynamical systems. For linear systems, we show that observables satisfy a closed differential equation whose minimal order is determined by…

Model Selection and Parameter Estimation of Multi-dimensional Gaussian Mixture Model
Xinyu Liu, Hai Zhang
In this paper, we study the problem of learning multi-dimensional Gaussian Mixture Models (GMMs), with a specific focus on model order selection and efficient mixing distribution e…
