1. Introduction to Adaptive Filters
Adaptive filtering, is to use the results of the filter parameters obtained in the previous moment, automatically adjust the current moment of the filter parameters to adapt to the signal and noise unknown or

The Gini filter parameters are fixed and suitable for Stable Random Signals. 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
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
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
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 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
called classification problem.Linear regressionSuppose the price is not only related to the area, but also to the number of bedrooms, as follows:At this time \ (x\) is a 2-dimensional vector \ (\in \mathbb{r^2}\). where \ (x_1^{(i)}\) represents the house area of the first ( i\) sample,\ (x_2^{(i)}\) represents the number of house bedrooms for the first \ (i\) sample.We now decide to approximate y as the linear function of x, which is the following formula:\[h_{\theta} (x) =\theta_0+\theta_1x_1
1.LMS algorithms are primarily a matter of relevance2. What is the implementation process of LMS algorithm?3. 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

After the system is complete, it is time to test the system. This must have been the first system of acceptance. We are confident that the system will be accepted by the master. Once it comes to the master, nothing will happen, in addition, so
Software can be roughly divided into: Free Software and non-free software
Types of Free Software and non-free software.The following are some terms that are frequently mentioned when discussing free software. They explain which types overlap with others or are part of o
In the past, I have read many articles about the top ten essential tools for developing common professional software such as. NET and. Net programmers. Today, I don't want to introduce these professional software. I want to introduce some auxiliary software that is often used during development to help us complete better development.
I recommend commonly used a
period, the CS is not, other industries worse. When the economy improves, CS lead. There's a representative billionaire who says, "Software will swallow the world." human beings just develop software, let the software command the machine, all other working bots will help you. You are the mouth cannon, these rich people use their own huge amount of money

Status Quo,
At present, many software companies in China are still working in small workshops!
After receiving a project, let's discuss how to do it. After the boss decides to make a decision, let's split our heads!
As a result, a project started, and everyone was busy in the early stage!
Everyone has their own jobs (some companies are unevenly allocated. If there are idle people,

Most of our Linux system is a Linux manufacturer's system, so these vendors can compile some software to provide users to download, the user after downloading can be installed directly, thus eliminating the compilation of the source code and the process of various problems. At this point we can use the appropriate software manager to ope
The structure diagram proposed by Yourdon is another powerful tool for software structure design. A structure diagram is similar to a hierarchy diagram, and is also a graphical tool for describing software structures, in which a box represents a module with the name or main function of the module; the arrow (or line) between the boxes represents the calling relationship of the module. Because the formula is
