Answer the following questions: a) State two advantages of the "orthogonal least square (OLS)' method in respect to the "forward selection" method. b) Using recursive least square (RLS) method with forgetting factor, we want to identify a time-varying linear system whose parameters are changed slowly. Do you choose a large vahue for the forgetting factor or a small one? Why?
