Fusing Two Kinds of Virtual Samples for Small Sample Face Recognition

Algorithm 2

The TPTSR algorithm.

(1) Normalize the columns of and to have unit -norm

(2) Solve

   If is singular, , where is a small

positive constant and is the identity matrix.

   If is not singular, .

(3) Compute the deviation

(4) Output the training samples that have the greatest contributions

(5) Solve

   If is singular, , where is a small

positive constant and is the identity matrix;

   If is not singular, .

(6) Compute the deviation

(7) Output the identity of as
