This is an adaptive method, which implies it doesn't need a priori Whether your application is business, how-to, education, medicine, school, church, sales, marketing, online training or just for fun, PowerShow.com is a great resource. Dynamic estimation of TRFs was first discussed in using a Recursive Least Square (RLS) algorithm. The example applica-tion is adaptive channel equalization, which has been introduced in compu-ter exercise 2. Example Room. Given a model for the observations {(x t,y t)} t â¢ Rdâ¥1 given as y t = T 0 x t +e t, 8t =1,2,..., (8.8) where 0 2 Rd and the terms {e t} t are the corresponding residuals. Leaded by the cost function of the least-squares, this algorithm presents a fast convergence with a good stability. The key problems of this algorithm are high complexity and numerical instability. hands-free .
