Analytical:Two categories: Each classifier can only divide the samples into two categories. The prison samples were warders, thieves, food-delivery officers, and others. Two classifications certainly won't work. Vapnik 95 proposed to the basis of the support vector machine is a two classification classifier, this classifier learning process is to solve a positive and negative two classification derived fro

Nonlinear Transformation (nonlinear conversion) ReviewIn the 11th lecture, we introduce how to deal with two classification problems through logistic regression, and how to solve multiple classification problems by Ova/ovo decomposition. Quadratic hypothesesThe two-time hypothetical space linear hypothetical space is extremely flawed: So far, the machine learning model we have introduced is linear model,

Which programming language should I choose for machine learning ?, Machine Programming Language Which programming language should developers learn to get jobs like machine learning or data science? This is a very important issue. We have discussed this issue in many forums.

: , where θ is the vector of (n+1) x1, x is the vector of (n+1) x1, ∙. We all use vectors to represent the hyper-plane behind. Except that θ is called a weight, and b is biased, so the complete expression of the super plane is:θ*x+b=0 The Perceptron model can be defined as y=sign (θ∙x+b) where: If we call sign the activation function, the difference between the perceptual machine and the logistic regression is that the sign,logistic regression acti

Brief introduction:Support Vector Machine (SVM) is a supervised learning model of two classification, and his basic model is a linear model that defines the largest interval in the feature space. The difference between him and the Perceptron is that the perceptron simply finds the hyper-plane that can divide the data correctly, and SVM needs to find the most spaced hyper-plane to divide the data. So the per

We have developed a false news detector using machine learning and natural language processing, which has an accuracy rate of more than 95% on the validation set. In the real world, the accuracy rate should be lower than 95%, especially with the passage of time, the way the creation of false news will change. Because of the rapid development of natural language processing and

is all 0. And because it can be deduced that b=1nz∗zt=wt∗ (1NX∗XT) w=wt∗c∗w, this expression actually means that the function of the linear transformation matrix W in the PCA algorithm is to diagonalization the original covariance matrix C. Because diagonalization in linear algebra is obtained by solving eigenvalue and corresponding eigenvector, the process of PCA algorithm can be introduced (the process is mainly excerpted from Zhou Zhihua's "machine
