3: Initialize all

4: While convergence criterion not met do

5: Choose a

6: If and

  then add to the model

7: Else if and

  then re-estimate using (7)

8: Else if

  then prune ith column of from the model and set

 End if

9: Update using (5) and (6)

10: Update , using (8)∼(11)

11: Update using (12)∼(15)
