have good generalization performance (that is, the test error is small). The usual methods for solving overfitting problems are as follows:1. Reduce the number of features2. Manually Filter Features3. Using feature screening algorithms4. Regularization: Retain all characteristics, but as far as possible to make the parameter θjθj as small as possible.Regularization is useful in situations where many feature variables have only a small effect on the target value. Second, regularization Regulariz

next.Next, we use the logistic regression model as the basis to see how the regularization term affects our model by seemingly simple norms to prevent overfitting. The first norm regularization term Definition: The first norm defines l1:∑ni=1|wi| L_1:\sum_{i=1}^{n}|w_i|, in short, is the absolute value of each parameter only. model changes: The original LR model optimization goal is to minimize the loss function, namely:L (W) =1n∑n1 (f (xi,w) −yi) 2 L (W) =\frac{1}{n}\sum_1^n (f (x_i,w)-y_i) ^2

, the point in the figure is a training sample, the curve through these points are theoretically satisfied with the "condition" of the hypothetical model, but we intuitively prefer the smooth blue dashed line instead of red. If the algorithm is an inductive preference, we think that the smoothed Blue line is the "right" model that we recognize. -------------------------Selection Method------------- Ames Razor (Occam ' Srazor): If there are multip

　　most of the tags in the HTML have some bad style, some of the tags naturally come with, some browser default settings, we are writing Web pages, these default styles will occasionally jump out of the mess, make us very helpless. So when you write a CSS style, you usually write a initialization program at the beginning to get rid of these default styles, such as the simplest square method is to use *{margin:0;padding:0;}. But usually we seldom use this method, because the wildcard * is very ine

world. If they are not involved in computer science, they will have outstanding achievements in other fields, and we have brought a humanistic atmosphere to the computer. This kind of humanistic attitude makes it impossible for us to introduce ideas from other fields with a narrow vision.We can make a small thing to control huge things.My first computer contact was about ten years old. I saw it at the Space Department's Ames Research Center. At that

For the public and most military fans, the famous military generals during the Second World War were nothing more than those of Eisenhower, nimiz, Montgomery, longmmel, and Zhukov. But one of them is little known. This guy is neither a marshal nor a marshalThe fifth star was a low profile and even refused to show off the limelight. However, his path exists among the stars of World War II. He is the "general in the general" sprunns (Raymond Ames Spruan

ensure that all the code I write is valuable and there is no "surprise code" that will cause problems in the future ". I will try to make the coverage rate higher. I agree to correctly check the integration status of the Code. After I finish writing my code, I will check my code with other developers to ensure that they can work correctly with others' code and deliver the client request function.
