Article Title: surpassing a single CUP: hyper-threading accelerates Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 Introduction Intel's hyper-threading technology allows a physical processor to contain two logical processors by replicating, partitioning, and sharing resources in the Intel NetBurst microarchitecture pipeline. 　　 The copied resource

. Aiming at the problem of macroscopic perception, this paper presents a flood DDoS attack perception method based on the fast fractional order Fourier transform to estimate Hurst, and uses the influence of DDoS attack on the self-similarity of network traffic, and by monitoring the Hurst index change threshold to determine whether there is DDoS attack, compared with the method of wavelet analysis. , the method has the advantages of low computational complexity, high precision of Hurst, and high

likelihood estimator, called θ, is recorded as:Sometimes, you can see that L (θ) is a multiplicative, so for the sake of analysis, you can also define a log-likelihood function and turn it into a plus:Well, now that we know that, to ask for Theta, we need only to make the likelihood function of theta (θ) greater, and then the maxima corresponding to Theta is our estimate. Here we go back to the question of finding the most value. How do I find the ma

and nonlinear regression analysis. If in regression analysis, only one argument and dependent variable are included, and the relationship can be approximated by a straight line, this regression analysis is called unary linear regression analysis. If the regression analysis includes two or more independent variables, and there is a linear correlation between the arguments, it is called multiple regression analysisThe principle of Ridge regression: The principle of ridge regression is more compli

In addition to the algorithms, AML integrates packages that 400+ multiple R languages.The choice of the algorithm, whether for beginners or experienced data scientists, in fact, is a very cost-minded thing. Microsoft also provides a lot of information to help you decide which algorithms to choose.

The derivative of the Logistic function can be represented by the original function, i.e.This conclusion will be used when learning the parameter \theta later.2 study on model parameters of logistic regression with maximum likelihood estimation and gradient ascent method \thetaGiven the new hypotheses function H_\theta (x), how do we learn the parameter \theta based on the training sample? We can c

massive data processing because it separates the datasets as expected. This allows us to split the datasets into more manageable data, then use a merge sort to process the data and then merge the data continuously, without having to store all the data at once.Polynomial interpolationA method of finding the approximate value of a function. Where the function value is known only on a few points. The basis of this algorithm is to establish an interpolation polynomial pn (z) with a progression of l

The bandwidth adaptive algorithm in WEBRTC is divided into two types: 1, the originator bandwidth control, the principle is the RTCP in the packet loss statistics to dynamically increase or decrease the bandwidth, in the reduction of bandwidth using the TFRC algorithm to increase the smoothness. 2, the receiver bandwidth estimation, the principle is and by the receipt of RTP data, the estimated bandwidth, with the Kalman filter, the transmission time and reception time of each frame is analyzed,
