Gauss-Newton errorminimization is used to transform six-dimentional reference vector to quaternion as a part of observations for EKF, which significantly reduces the computational requirement.
It operates on a principle, called structural risk minimization, which aims to minimize the upper bound on the expected generalization error.
它基于结构风险最小化准则，目的是最小化泛化误差上界。

An optimal subband rate allocation algorithm in mean-squared error (MSE) minimization sense was proposed, which achieves persistent optimal rate-distortion performance under any given rate constrains.
