Article Introduction：Introduction In the era of information explosion, data has become one of the most valuable assets of enterprises. However, if a large amount of data cannot be effectively classified and classified, it will become disordered and chaotic, data security cannot be effectively guaranteed, and its true data value cannot be exerted. Therefore, data classification and grading have become crucial for both data security and data value. This article will discuss the importance of data classification and classification, and introduce how to use machine learning to achieve intelligent classification and classification of data. 1. The Importance of Data Classification and Grading Data classification and grading is the process of classifying and sorting data according to certain rules and standards. It can help enterprises better manage data and improve data confidentiality, availability, integrity and accessibility, thereby better supporting business decisions.

Article Introduction：Infinitus seven-core water purifier: Infinitus seven-core water purifier uses php+mysql to achieve infinite classification | Tree display classification relationship: infinite classification is mainly achieved by storing the id and classification path of the upper-level classification. Since the structure of the data is simple, to display the classification relationship in a tree, I can only think of using recursion to implement it. Unlimited classification is mainly achieved by storing the id and classification path of the upper-level classification. Since the data structure is simple, I want to display the classification relationship in a tree shape. I can only think of using recursion to implement it. The following is the classification data table structure and a tree display function written by myself. What is wrong? I hope everyone can point it out. Table structure: The id field is the classification identifier.

Article Introduction：Categorization or Classification is to label objects according to a certain standard, and then classify them according to the label. Classification is to define categories in advance, and the number of categories remains unchanged. The classifier needs to be trained from manually labeled classification training corpus, which belongs to the category of guided learning.

Article Introduction：In web development, various classification systems are widely used, and Infinitus classification is one of the common classification methods. Infinitus classification refers to a classification method that does not limit the number of classification levels in the classification system, so its array structure requires special processing. PHP language is often used in web development. Let’s discuss the placement method of PHP Infinitus classification array. 1. Recursive method The recursive method is the most commonly used method in PHP Infinitus classification array. It relies on recursive calls of functions to construct classified data. The recursive way is written as follows: ```/** * Infinitus

Article Introduction：The machine learning classifier algorithm is an algorithm widely used in data mining, artificial intelligence and other fields. It can help solve practical problems by classifying and predicting data, and therefore plays an important role in modern artificial intelligence technology. Some commonly used machine learning classifier algorithms will be briefly introduced below. 1. Decision tree classifier Decision tree is a classifier based on a tree structure. It performs classification by dividing the data set into multiple subsets, where each subset corresponds to a node of the tree, ultimately forming a complete decision tree. During the classification process, the decision tree is traversed layer by layer according to the value of the feature until it reaches the leaf node, thereby obtaining the final classification result. Decision tree classifiers have the advantage of being easy to understand and interpret, but they are also prone to overfitting problems.
