Title: Multi-scale two-directional two-dimensional
principal component analysis and its application
to high-dimensional biomedical signal
classification
Abstract— Goal: Time-frequency analysis incorporating the wavelet transform
followed by principal component analysis(WT-PCA) has been a powerful
approach for the analysis of biomedical signals such as electromyography
(EMG),electroencephalography (EEG), electrocardiography (ECG), and Doppler
ultrasound. Time-frequency coefficients at various scales were usually transformed
into a one-dimensional array using only a single or a few signal channels. The
steady improvement of biomedical recording techniques has increasingly permitted
the registration of a high number of channels. However, WT-PCA is not applicable
to high-dimensional recordings due to the curse of dimensionality and small
sample size problem. In this study, wepresent a multi-scale two-directional two-
dimensional principal component analysis (MS2D2PCA) method for the efficient
and effective extraction of essential feature information from high-dimensional
signals. Multi-scale matrices constructed in the first step incorporate the spatial
correlation and physiological characteristics of sub-band signals among channels.
In the second step, the two-directional two-dimensional principal component
analysis operates on the multi-scale matrices to reduce the dimension, rather than
vectors in conventional PCA. Results are presented from an experiment to classify
20 hand movementsusing 89-channel EMG signals recorded in stroke survivors,
which illustrates the efficiency and effectiveness of the proposed method for high-
dimensional biomedical signal analysis.

Time-frequency coefficients at various scales were usually transformed into a one-dimensional array using only a single or a few signal channels. The steady improvement of biomedical recording techniques has increasingly permitted the registration of a high number of channels. However, WT-PCA is not applicable to high-dimensional recordings due to the curse of dimensionality and small sample size problem. In this study, wepresent a multi-scale two-directional two- dimensional principal component analysis (MS2D2PCA) method for the efficient and effective extraction of essential feature information from high-dimensional signals. Multi-scale matrices constructed in the first step incorporate the spatial correlation and physiological characteristics of sub-band signals among channels. In the second step, the two-directional two-dimensional principal component analysis operates on the multi-scale matrices to reduce the dimension, rather than vectors in conventional PCA. Results are presented from an experiment to classify 20 hand movementsusing 89-channel EMG signals recorded in stroke survivors, which illustrates the efficiency and effectiveness of the proposed method for high- dimensional biomedical signal analysis. .
