Least mean squares filter - HandWiki
WebAug 17, 2024 · The least mean square algorithm uses a technique called “method of steepest descent” and continuously estimates results by updating filter weights. Through the principle of algorithm convergence, the least mean square algorithm provides particular learning curves useful in machine learning theory and implementation. Many of these … Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean square of the error signal (difference between the desired and the actual signal). It is a stochastic gradient descent method in that the filter … See more Relationship to the Wiener filter The realization of the causal Wiener filter looks a lot like the solution to the least squares estimate, except in the signal processing domain. The least squares solution, for input … See more For most systems the expectation function $${\displaystyle {E}\left\{\mathbf {x} (n)\,e^{*}(n)\right\}}$$ must be approximated. This … See more The main drawback of the "pure" LMS algorithm is that it is sensitive to the scaling of its input $${\displaystyle x(n)}$$. This makes it very hard (if not impossible) to choose a learning rate $${\displaystyle \mu }$$ that guarantees stability of the algorithm (Haykin … See more The basic idea behind LMS filter is to approach the optimum filter weights $${\displaystyle (R^{-1}P)}$$, by updating the filter weights in … See more The idea behind LMS filters is to use steepest descent to find filter weights $${\displaystyle {\hat {\mathbf {h} }}(n)}$$ which minimize a cost function. We start by defining the cost … See more As the LMS algorithm does not use the exact values of the expectations, the weights would never reach the optimal weights in the absolute sense, but a convergence is … See more • Recursive least squares • For statistical techniques relevant to LMS filter see Least squares.
