Course Introduction:The weight of pseudo elements is 0. In CSS, selector weight is used to determine the priority of styles. The higher the weight value, the higher the priority and the style will be applied. This means that no matter where the pseudo-element selector appears in the selector, it has the lowest weight. Even when combined with other selectors, the weight of a pseudo-element selector does not affect the weight of the entire selector. No matter what the weight of other selectors is, the styles of pseudo-element selectors will not be overridden, etc.

Course Introduction:For Douyin users, the weight of the account is very important because it directly affects the exposure and traffic of the account. On the Douyin platform, the weight of an account is related to factors such as the video's completion rate, number of likes, number of comments, number of forwards, and attention. The weight of accounts is divided into four levels, including zombie accounts, lowest weight accounts, accounts to be recommended and accounts to be popular. These levels determine the level of recommendation and exposure of the account on the Douyin platform, thereby affecting users' attention and interaction. Therefore, Douyin users need to work hard to increase the weight of their accounts and attract more user attention and participation by improving video quality and increasing interaction. In this way, you can get more exposure and traffic on the Douyin platform. Specifically, a zombie account refers to a work that has been released for seven consecutive days, but the playback volume is only

Course Introduction:In this article, the given task is to find the total weight of a string. To calculate the string weight, we convert the given string into a lower form. Considering the weight of characters, we take a=1, b=,2 and so on until z=26. In this Python article, a method for finding the weight of a given string is presented using two different examples. In the first example, the given characters in the string are fetch, hed and then their respective weights are added to the updated weights. In Example 2, you first calculate how often a given character appears in the string, then multiply that frequency by the corresponding character weight, and then add all these component weights together to get the final result. Example 1: Find string weight and add characters using iteration

Course Introduction:Weight decay is a commonly used regularization technique that implements regularization by penalizing the weight parameters of the model. In deep learning, the over-fitting problem is often caused by the model being too complex and having too many parameters. The function of weight attenuation is to reduce the complexity of the model and reduce the risk of overfitting by penalizing the weight of the model. This penalty is achieved by adding a regularization term to the loss function that is proportional to the sum of the squares of the weight parameters. During the training process, weight decay will make the model more inclined to choose smaller weight values, thereby reducing the complexity of the model. By appropriately adjusting the coefficient of weight attenuation, the fitting ability and generalization of the model can be balanced. Weight attenuation is an effective method to suppress the over-fitting problem of deep neural networks. it passes
