Problems solved by technology
Some traditional decision trees mainly use probability to evaluate a risk situation, but when the business that requires decision-making is more complicated, a series of variables are needed to judge. At this time, it is difficult to convert variables into probability distributions and then configure decision-making Tree

Embodiment Construction
[0050]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0051] The decision tree configuration method provided by this application can be applied to such as figure 1 shown in the application environment. In this application environment, a terminal 102 and a server 104 are included.
[0052] Terminal 102 moves multiple service nodes to the main page; for each service node, in response to the configuration operation of the current service node, terminal 102 displays the configuration page of the service node on the upper layer of the main page; if the current service node is an execution node, Terminal 102 configures the node ty...

The invention relates to a decision tree configuration method and device, computer equipment and a storage medium. The method comprises the following steps: moving a plurality of service nodes to a home page; for each service node, in response to a configuration operation on the current service node, displaying a configuration page of the service node on the upper layer of the main page; if the current service node is an execution node, configuring a node type and a decision strategy of the execution node in a configuration page; if the current service node is a data node, configuring the data node based on a variable obtained in the configuration page; if the current service node is an end node, configuring the end node based on a decision condition obtained in the configuration page; and generating a decision-making tree based on each service node, and performing risk decision-making on the user behavior based on the decision-making tree. By adopting the method, risk decision-making can be carried out on complex services.
Description
technical field [0001] The present application relates to the technical field of data processing, in particular to a decision tree configuration method, device, computer equipment and storage medium. Background technique [0002] With the development of information technology, a method of using data structure for decision analysis has emerged. Decision tree is a machine learning method based on tree structure. Decision tree has good interpretability, can effectively help decision makers to carry out decision analysis, and is widely used in bank credit modeling. Modelers can manually configure the tree structure and affiliation relationship to obtain a decision tree. Some traditional decision trees mainly evaluate a risk situation through probability, but when the business that requires decision-making is more complicated, a series of variables are needed to judge. At this time, it is difficult to convert variables into probability distributions and then configure decision-...
