Decision tree and rule engine, decision tree Rule Engine Use of Decision TreesDecision Trees are often used in data mining and are one of the most basic algorithms. Almost everyone who has learned Data Mining knows decision trees. However, the original use of the restored decision tree is more practical and intuitive when used for decision making or decision-making. Its tree structure guides people to focus

advance, generally need to find an optimal K value through many experiments, and then, The algorithm is less tolerant to noise and outliers, since the algorithm initially adopts the method of randomly selecting the initial clustering center. Noise is the wrong data in a clustered object, and outliers are data that is far away from other data and less similar. For the K-means algorithm, once the outlier and noise are selected as the cluster center at the very beginning, the whole clustering proc

Features of the MyISAM storage table:Use three files per table to save. frm: Table structure definition file. MYD: Table data file, storing data. MYI: Table Index fileInnoDB Storage Table Features:InnoDB When you save a table, you share multiple table data in a tablespace file. This method is not easy to maintain the table. Therefore, it is recommended that each table use a separate tablespace file.Therefore, you need to edit the MySQL configuration file, add the following line:#vim/etc/my.cnfin

When I first used MySQL Administrator to create a database, the table is of the InnoDB type by default, so I did not care about it. Later, when using Access2MySQL to export data, I found that only tables of the MyISAM type can be imported. I checked the differences between the two types. Originally, the MyISAM type does not support advanced processing such as transaction processing, while the InnoDB type does. MyISAM tables emphasize performance, and the execution speed is faster than that of In

Adding a Cache mechanism is perfect! I don't know if the performance of the regular template engine will be higher than that of the template engine. it can be used in self-written programs for convenient calling. The code is as follows: $ A = array ( 'A', 'B', 'C' ); Require 'Template/demo. php'; // reference the template ?> Template File: The code is as follows: Template test

Because the report is complex and involves data from multiple tables, and the report format is complex, all the data required for the report is calculated during design and then saved to dataset, dataset contains six tables, and then writes dataset to the XML file. Then, the XML file is used as the design basis for the report data fields. // Display the report.

When you first build a database with MySQL administrator, the table defaults to the InnoDB type, and you don't care. Later, when using Access2mysql to guide the data found can only lead to myisam type of table, do not know what the difference between the two types, went to check. The MyISAM type does not support advanced processing, such as transaction processing, but InnoDB type support. Tables of the MyISAM type emphasize performance, which executes more than INNODB types faster, but does not

are put into the postingtable. 14. Sort the postingtable After all entries are added to the postingtable, Lucene first converts the postingtable into an array of posting types, then sorts the array so that all the entries are in their dictionary order. That way, you can write the entry information to the. tii and. tis files. In addition, the frequency and position information are written into the. Frq and. prx files. (A quick Sort method is used in Lucene to sort this posting array). Why should
