words, the non-miscible noise generation. Therefore, the correlation matrix can only be estimated, so that the actual weight adjustments can not be one step. And the steepest descent method, in strict accordance with the direction of gradient descent, more easy to operate. LMS algorithm: (practical)The abbreviated version of the steepest descent method, which takes only one sample as the current estimate, proves that the

Kalman filter parameters are time-varying and suitable for non-Stable Random Signals. However, the two filters can obtain optimal filtering only when the statistical characteristics of signal and noise are a prior known. In practical applications, we often cannot obtain a prior knowledge of the statistical characteristics of signals and noise. In this case

The LMS algorithm, which is the minimum mean variance, is the sum of squares and minima of errors.Using gradient descent, the so-called gradient drop, essentially using the nature of the derivative to find the location of extreme points, the derivative in the vicinity of the side is greater than 0, one side is less than 0, that's all ...And in this, the positive and negative of the derivative, is dependent on the error of the positive or negative to d

### Python implements minimum mean square algorithm (LMS)

The main difference between LMS algorithm and Rosenblatt Perceptron is that the weight correction method is not the same. LMS uses the batch correction algorithm, which is used by the Rosenblatt Perceptron.is a single-sample correction algorithm. Both of these algorithms are single-layer perceptron and can only be used for linear sub-conditions.Detailed code and instructions are as follows: 650) this.width=

### LMS Algorithm de-noising

LMS is widely used in speech enhancement, and is one of the most common algorithms, which is also the theoretical basis or component of many more complex algorithms, such as the important method--GSC (generalized sidelobe cancellation) in array speech enhancement. The LMS algorithm extends from the original version to many variant structures, such as normalized LMS

How does stepping affect the algorithm?If the step size is large, the convergence is fast, but the offset is large and the step size is small, but the convergence is slow.In the initial phase of the algorithm, a large U-value should be adopted to accelerate the convergence, and then the smaller U-va
