法国数学家勒让德于1806年首次发表最小二乘理论。 德国的高斯于1794年已经应用这一理论推算了谷神星的轨 道，但迟至1809年才正式发表。 CH6 LS Method RLS Algorithm RLS procedure is derived from least squares estimation theory. The LMS algorithm may then be viewed as a pruned version of the RLS algorithm. In contrast to the usual approach in which the LMS algorithm is derived from Wiener filter theory,based on steepest-descent optimization and instantaneous estimates of the process statistics.CH6 LS Method & RLS Algorithm RLS procedure is derived from least squares estimation theory.
