Muscle Activity Analysis Using Higher-Order Tensor Decomposition: Application to Muscle Synergy Extraction
Muscle Activity Analysis Using Higher-Order Tensor Decomposition: Application to Muscle Synergy Extraction
Higher order tensor decompositions have hardly been used in muscle activity analysis despite multichannel electromyography (EMG) datasets naturally occurring as multi-way structures. Here, we seek to demonstrate and discuss the potential of tensor decompositions as a framework to estimate muscle synergies from the third-order EMG tensors built by stacking repetitions …
