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
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 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
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=
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
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
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
basically, "Good Voice of China" can be successful because it cleverly draws on the strengths of "qingsong competition" and "Super Girl sound" programs. As we all know, the qingsong competition is a very professional singing competition, and there is no doubt about the contestant level. However, there is little innovation in the competition process and Competition System of the qingsong competition, therefore, it is not as influential as the entertainment-oriented Talent Show "super girl voice.
For companies in the embedded field, the development model of platforms and products should be determined based on the company's scale and nature. That is to say, developing small products on big platforms is still developing large products on small platforms. If the company has a large scale, but its products have different application fields and involve a large
Development: distinguishes public platforms from open platforms, public account global creden, and webpage authorization creden,.
Although the company's own websites and projects developed for customers involve development, they have also written two articles on development, but they feel that they are easy to confuse some concepts in development, today, I browsed the public platform, Open Platform backgrou
As we all know, Unity3d engine with a strong cross-platform ability and the favor of developers, in the Cross-platform application development gradually become mainstream today, with cross-platform development capabilities for programmers is particularly important. The traditional way to develop for different platforms often gives developers a different approach, and it is difficult to ensure that the application has the same and excellent experience
The first part security Configuration and Code encapsulation
Security Configuration
Two platforms are configured through XML or plain text files, and the biggest difference between the two platforms is the way the security configuration system is handled.
On the. NET platform, there are graphical interfaces and command line two ways to modify security configuration parameters. Mscorcfg.msc is a graphical
Supports common mainstream platforms such as AIX, HPUX, Solaris, Linux, Windows, etc., UNIX, Linux platforms that are common except for Windows, have native Python, but generally have a lower version. As for cross-platform and his cross-platform language, it is important to note that some individual modules are unique to a single platform, and that the overall cross-platform is good enough not to write mult
Here is a few common, but also easy to use several methods of platform judgment.1. First of all, it is also a handy one for me. Using Runtimeplatform to judge, the explanation on the API is that [the platform application is running. Returned by Application.platform.]For a chestnut: if (application.platform = = Runtimeplatform.windowseditor) {}Generally used is three platforms, Android [Android], Apple [iphoneplayer],unity Editor [Windowseditor].2. The
flat-end app application, presumably also is not a matter of trouble.

into the intermediate code of the compiler is independent of the platform, the intermediate code generated by the compiler is also independent of the platform (once compiled, run everywhere), the intermediate code is interpreted by the interpreter execution, the interpreter is platform-related, that is, different platforms need different interpreters.Java is first compiled and then explainedThe same. class file gets different machine instructions (di

Google brand new logo release: To adapt to more platforms-brothers and IT education
September 2 News, early this morning, Google suddenly announced the adoption of a new logo logo, the company said the purpose of the change is to be able to adapt to smart phones, watches, cars and other mobile intelligent terminals. The Google logo change is also since 1998 the company since the birth of the largest logo style change.
The new logo is still "GOOGLE" si
