Classification is a machine learning model that you can use to identify the classes of system objects online. For example, you can use the model to identify attack requests. You can also use the model to identify the relationships between elements. This topic describes the syntax of classification analysis functions. This topic also provides examples on how to use the functions.
Background information
The following figure shows sample indexes for the classification analysis functions. For more information, see Create indexes.

Functions
You can use the machine learning model of classification to identify the classes of system objects online.
Function | Syntax | Description | Data type of the return value |
decision_tree_classifier( target_variable varchar, input_variable_array array(varchar), target_variable_name varchar, input_variable_name_array array(varchar), input_variable_type_array array(varchar), <optional> model_options varchar ) | Returns a trained decision tree model that can be used for data classification and cause analysis based on the recently specified samples. | varchar | |
decision_tree_predict( decision_tree_model_in_json varchar, input_variable_array array(varchar) ) | Identifies the classes of system objects based on the specified samples and the decision tree model that is returned by the decision_tree_classifier function. | varchar |
decision_tree_classifier function
The decision_tree_classifier function returns a trained decision tree model that can be used for data classification and cause analysis based on the recently specified samples.
varchar decision_tree_classifier(target_variable varchar,input_variable_array array(varchar),target_variable_name varchar,input_variable_name_array array(varchar),input_variable_type_array array(varchar),<optional> model_options varchar)
Parameter | Description |
| The output variable. |
| The array of input variables. The function converts the input variables to the string type and forms a one-dimensional array. |
| The name of the output variable. |
| The array of input variable names. |
| The array of input variable types. Supported input variable types:
|
| The advanced parameters of the decision tree model. In most cases, you do not need to configure this parameter. The value consists of key-value pairs. Multiple key-value pairs are separated with commas (,) or semicolons (:). For example, you can specify Advanced parameters of the decision tree model:

Query and analysis results
The
sleep_health_model
field indicates the decision tree model. ThedecisionTreeEncode
field indicates the serialization results of the decision tree model. This function returns a decision tree model that you can use in the decision_tree_predict function to identify the class of a system object.group_id
