We propose a new LMS algorithm with an adaptive neural network cost function (ANNCFLMS) for application to unknown channel estimation or system identification. The algorithm employs the weighted average of a neural network with two input signals-the squared errors at adjacent time intervals-to ...

As it is an online algorithm, the user may update the model anytime by calling learn even after calling the finish method. In the example, we show another way of learning by working on single sample. As shown in the example, we simply call the predict method on a testing sample. Both...
In this paper a nonlinear adaptive algorithm based on a kernel space least mean squares (LMS) approach is presented. With most of the neural network based methods for time series modeling it is difficult to implement a sample-by-sample adaptation method. This puts a serious limitation on the ...
This letter presents a novel variable-length least mean square algorithm, whose filter length is adjusted dynamically along the negative gradient direction of the squared estimation error. Compared with other variable-length algorithms, the proposed algorithm has faster convergence and more robust performan...
