Php interface and front-end data interaction implementation sample code, front-end sample code
Recent attempts to interact with frontend and backend data have also encountered many pitfalls. php + bootstrap-table + js is used to record some gains and facilitate query.

Sometimes we often encounter in the actual classification data mining, the class sample is very uneven, the direct use of this unbalanced data will affect the classification of some models, such as the logistic REGRESSION,SVM, a solution is to balance the data sampling, here provides a recommended code implementation ,

Use the Sample parameter of DataPump for data sampling.
Data Pump Datapump is a convenient data logical backup and restoration tool launched by Oracle. Compared with the traditional Exp/Imp, Datapump provides many advantages in both performance and functionality. In practice, big d

Assuming that the positive class sample is far more than the negative class
1, linear can be divided into the situation
Suppose the real dataset is as follows:
Because the negative sample size is too small, this situation may occur
It makes the separating hyperplane biased towards the negative class. Strictly, this
SQL Server 2005 introduces a new feature tablesample to randomly retrieve some sample data from an existing table, which can specify the number of rows,
You can also specify the percentage. For example:Select *From performance. DBO. Orders tablesample (1000 rows );
Select *From DBO. Orders tablesample (0.1 percent );
However, it is worth noting that,It does not mean that the specified number of

fill spaces in a fixed layout TABLE.To get COLSPAN, enter the name of the current context (specified by "." here) and computing node. In the function, obtain the number of nodes specified in the current context, paraentNode, and XPath query. Then, the function returns this quantity and adds it to fill in the TD.With this TD, another TABLE is embedded in the TABLE, which contains every file in the file group. From this point on, the process is the same as external TABLE conversion. The last step
