Candidates for Synergies: Linear Discriminants versus Principal Components

<table>Mean reconstruction errors for PCA (blue) and ULDA (red) using up to 10 synergies are shown. Reconstruction errors for natural grasping movements were less for PCA derived synergies than ULDA derived synergies. Reconstruction errors for ULDA plateaued after 5 synergies.</table>
