mean square error

基本解释

However, two-stage estimates of regression coefficients corresponding to these two estimates have approximate equal mean square error.
对应于方差参数这两种估计的回归系数的两种两步估计，它们的均方误差大致相当。
Both channel and echo response can be shortened at random with a single FIR equalizer by following the minimum mean square error rule.
使用最小均方误差准则，用一个FIR均衡器联合缩短信息与回波冲激响应，有效地缩短了回波和信道冲激响应长度。
In comparison with traditional LMS algorithm, WO-LMS algorithm can achieve both lower steady mean square error and faster convergence speed.
与传统的LMS算法相比，WO-LMS算法既提高了收敛速度又可以得到较低的稳态均方误差。
