Secondly, on the assumption that the phase error on the aperture led by the random surface error obeys the Gaussian distribution with zero mean, the expression of the average power pattern is deduced.
然后在设定由随机表面误差引入的口径相位误差服从均值为零的正态分布的条件下，推导了天线平均功率方向图的计算公式。
It obtains low average mean squared error (MSE), fast convergence velocity and decreases the noise sensitivity at the same time.
该方法计算简单、均方误差小、收敛速度快，并且降低了算法对噪声的敏感性。
As the name suggests, the mean absolute error is an average of the absolute errors, where is the prediction and the true value.
顾名思义，平均绝对误差是绝对误差的平均值，其中fi是预测值而yi是实际值。
