Principal component analysis and its generalizations for any type of sequence (PCA-Seq)
In the 1940s, Karhunen and Loève proposed a method for processing a one-dimensional numeric time series by converting it into multidimensional by shifts. In fact, a one-dimensional number series was decomposed into several orthogonal time series.

AR-PCA-HMM approach for sensorimotor task classification in EEG-based brain-computer interfaces [PDF]
We propose an approach based on Hidden Markov models (HMMs) combined with principal component analysis (PCA) for classification of four-class single trial motor imagery EEG data for brain computer interfacing (BCI) purposes. We extract autoregressive (AR)
