Algorithm 2
Regularized sample self-representation by
-norm (RSSR-LDL21).
Input: Train matrix , test data , the number of iterations and the regularization parameter . | Output: The corresponding predicted label distribution of test data , . | Initialize which is an identity matrix, set ; // Initialization | for to Iter do. | , // calculate | , // calculate | end for | ; // Removing the matrix part of matrix . | ; // Using the transition matrix to represent the distribution of the predicted labels. | ; // Because of and , the normalized , . |
