Before revision:  Results: The results show that the constrained Tucker method successfully identified the shared and task-specific synergies for all 3 DoF tensorsdirectly and it was robust to misassignments with regard to task-repetition information unlike NMF, thanks to exploring the multi-way structure of muscle activity.
After revision:  Results: The results show that the consTD method is suitable for synergy extraction compared to PARAFAC and Tucker. Moreover, exploiting the multi-way structure of muscle activity, the proposed methods successfully identified shared and task-specific synergies for all 3 DoF tensorsdirectly and it was robust to misassignments with regard to task-repetition information unlike NMF, thanks to exploring the multi-way structure of muscle activity.
