Abstract. This supplementary material derives Algorithm 1 in the paper to solve Robust Regression (RR) using the Augmented Lagrange Multiplier (ALM) method.

Solving RR as subproblems

As shown in the paper, using Augmented Lagrange Multiplier (ALM) method the original cost function of RR is transformed to:
