The least mean square (LMS) algorithm assumes a linear model of the form f(x)=θTx, with θ∈Rd, and a mean squared error loss function E(θ)=E[ei2] [1,2]. It is based on the stochastic gradient descent method, thereby, at each time instant ti,i=1,…,N, the instantaneous er...
1.When computation of LMS(Least Mean Square) algorithm is reduced, error of the gradient estimate is increased.由于以往小计算量最小均方算法在减小算法计算量的同时,增大了算法中的梯度估计误差,所以这些算法虽然计算量小但性能却比传统的LMS算法降低了许多。 2.An adaptive method based on least mean squa...

A new technique for the least-mean-squares (LMS) phase-unwrapping method is developed that incorporates the concept of branch cuts between phase singularities (residues), which are usually associated with the path-following gradient integration technique. These branch cuts are introduced by decomposition...
In particular, a quantized kernel least mean square (QKLMS) algorithm is developed, which is based on a simple online vector quantization method. The analytical study of the mean square convergence has been carried out. The energy conservation relation for QKLMS is established, and on this ...
