statistics and machine learning toolbox

The previous section in"machine learning from logistic to neural network algorithm", we have introduced the origin and construction of neural network algorithm from the principle, and programmed the simple neural network to classify and test the linear and nonlinear data. Looking at the previous section, it may be found that the algorithm implemented in the previous section is not perfect for classifying no

perform a multiple regression of over Million variables? The idea is ludicrous. That's because training VGG-16 is not multiple regression?—? it's machine learning. I would also like to point out that one of the differences between deep learning networks and traditional statistical models is their scale problems. The scale of the deep neural network is

. So, why is this so? The reason is simple: there are highly correlated variables in the data (up to 0.987 of the x1,x2 correlation), and the two variables are so similar, like two parallel vectors, that is, they're collinear . Popular, because two software is too similar, so that cannot judge who can contribute greater user satisfaction, the two 10:0 open, 5:5 Open, 0:10 open almost no difference. As can be seen from the above results, the standard error of β1 reached 2.3947 and β2 reached 2.4

　　From a statistical point of view, most of the methods of machine learning are statistical classification and regression method to the field of engineering extension.The term "regression" (Regression) was the origin of the British scientist Francis Galton (1822-1911) in a 1886 paper [1] to study the relationship between height and parental height of a child. After observing 1087 couples, the adult son was
