Tensor decomposition methods are widely used in various areas of science for multilinear feature extraction and dimensionality reduction of multi-way arrays. Linked CANDECOM/PARAFAC (CP) tensor decomposition (LCPTD) can be used for extraction of shar

This study explored the effect of kinesthetic motor imagery training on reaching-to-grasp movement supplemented by a virtual environment in a patient with congenital bilateral transverse upper-limb deficiency. Based on a theoretical assumption, it is

The paper describes an EMG signal analysis based on the wavelet transform, applied for the hand prosthesis control. Signal features are represented by wavelet coefficients. A cross-validation method is applied for the feature selection process. The c

One of the biggest problems of upper limb transplantation is lack of certainty as to whether a patient will be able to control voluntary movements of transplanted hands. Based on findings of the recent research on brain cortex plasticity, a premise c

In this study, we considered the problem of controlling a prosthetic hand with noisy electromyography (EMG) and mechanomyography (MMG) signals. Several dimensionality reduction methods were analyzed to assess their efficiency at classifying these sig

The paper discusses the problem of the process of quick recognition and classification of electromyographic signals in order to control a robotic prosthetic hand. The work is based on the assumption that during the recording of the movement, the sign

Basic tensor decomposition methods, such as CAN-DECOMIPARAFAC (CP) or the Tucker decomposition, decompose a single tensor into a set of factors. However, there are practical cases when decomposing two or more tensors jointly is very useful, e.g. for
