Candidates for Synergies: Linear Discriminants versus Principal Components

Figure 8

Top: the lowest reconstruction error for both methods in ASL postural movement reconstruction was found in ASL postural task number 29. Its reconstruction is shown using PCA and ULDA. Bottom: the highest reconstruction error for both methods was found in ASL task number 9. Its reconstruction is shown using PCA and ULDA. T:thumb; I: index finger; M: middle finger; R: ring finger; P; pinky finger; MCP: metacarpophalangeal joint; IP; interphalangeal joint; PIP: proximal IP joint.
