Slice Oriented Tensor Decomposition of EEG Data for Feature Extraction in Space, Frequency and Time Domains

Abstract: Abstract. In this paper we apply a novel tensor decomposition model of SOD (slice oriented decomposition) to extract slice features from the multichannel time-frequency representation of EEG signals measured for MI (motor imagery) tasks in application to BCI (brain computer interface). The advantages of the SOD based feature extraction approach lie in its capability to obtain slice matrix components across the space, time and frequency domains and the discriminative features across different classes without an… Show more

“…Some of the tensor decomposition formulations for a 3 mode tensor shown in Figure are as follows: (a) parallel factor analysis (PARAFAC), equivalently known as canonical decomposition (CANDECOMP)/canonical polyadic decomposition (CPD), where a tensor is described as a sum of rank-1 tensors, (b) Tucker decomposition, where the tensor is expressed as the sum of outer products of different rank factor matrices in each mode weighted by a hypercube, and more recently, (c) slice oriented decomposition, where a tensor is represented as the sum of an outer product of column vector of the n th mode factor matrix with tensor hyper-slices of the remaining modes. This decomposition, implemented on a three-way tensor of electroencephalogram (EEG) data, is seen to be robust to outliers and captures patterns in the slices …”

“…The reason is that the EEG signal is an electric activity of the brain measured by electrodes (channels), which placed on the scalp is a superposition of electric signals which are produced by a synchronous activity of numerous neurons. [4] The spatial propagation of the electric signal in the complex brain tissue is far from being straightforward. Moreover, various groups of neurons participate in various and sometimes independent tasks.…”
