Competitive principal component analysis for locally stationary time series

Abstract–A new unsupervised algorithm is proposed that performs competitive principal component analysis (PCA) of a time series. A set of expert PCA networks compete, through the Mixture of Experts (MOE) formalism, on the basis of their ability to reconstruct the original signal. The resulting network finds an optimal projection of the input onto a reduced dimensional space as a function of the...

Sparse Principal Component Analysis for High Dimensional Multivariate Time Series

We study sparse principal component analysis (sparse PCA) for high dimensional multivariate vector autoregressive (VAR) time series. By treating the transition matrix as a nuisance parameter, we show that sparse PCA can be directly applied on analyzing multivariate time series as if the data are i.i.d. generated. Under a double asymptotic framework in which both the length of the sample period ...

Dynamic Principal Component Analysis in Multivariate Time-Series Segmentation

Principal Component Analysis (PCA) based, time-series analysis methods have become basic tools of every process engineer in the past few years thanks to their efficiency and solid statistical basis. However, there are two drawbacks of these methods which have to be taken into account. First, linear relationships are assumed between the process variables, and second, process dynamics are not con...
