low-dimensional representation of the activation of 11 muscles during 3D motion
of the arm is defined by
= V
T
K (11.13)
where V is an 11 × 2 matrix, whose columns are the two first eigenvectors of G in
(11.10), resulting in the size of 2 ×m for matrix . Likewise, the low-dimensional
representation of joint angles during 3D motion of the arm is defined by
= W
T
(11.14)
where W is a 4 × 2 matrix, whose columns are the two first eigenvectors of H in
(11.11), resulting in the size of 2 ×m for matrix .
Using the above dimension reduction technique, the high-dimensional data of
muscle activations and
