Cluster Analysis on Locally Asymptotically Self-similar Processes with Known Number of Clusters
Qidi Peng, Nan Rao, Ran Zhao
We conduct cluster analysis on a class of locally asymptotically self-similar stochastic processes, which includes multifractional Brownian motion as a representative. When the tru…

Bernstein Lethargy Theorem and Reflexivity
Asuman Güven Aksoy, Qidi Peng
In this paper, we prove the equivalence of reflexive Banach spaces and those Banach spaces which satisfy the following form of Bernstein's Lethargy Theorem. Let be an arbitrary…

Covariance-based Dissimilarity Measures Applied to Clustering Wide-sense Stationary Ergodic Processes
Qidi Peng, Nan Rao, Ran Zhao
We introduce a new unsupervised learning problem: clustering wide-sense stationary ergodic stochastic processes. A covariance-based dissimilarity measure together with asymptotical…
