Before revision:  We then utilise the power tensor factorisation to create a novel direct method for shared and task-specific synergy estimation from two biomechanically related tasks by developing a constrained Tucker decomposition method .
After revision:  Furthermore, we proposed a constrained Tucker decomposition (consTD) method for efficient synergy extraction building on the power of tensor decompositions. This method is proposed as a direct novel approach for shared and task-specific synergy estimation from two biomechanically related tasks by developing a constrained Tucker decomposition method .
