Abstract

The invention provides a decision model construction method, a decision method and a decision model. The method comprises the following steps of sending an attribute number and a to-be-batched data number used by a to-be-constructed node in the current iteration to N data platforms; determining a task data platform corresponding to the to-be-constructed node according to the N maximum informationgain rates based on the batch attribute numbers sent by the N data platforms; sending a node construction notification to the task data platform, and obtaining a batch data number determined by the task data platform according to the batch attribute number and the to-be-batched data number; synchronizing the batch data numbers to the rest N-1 data platforms to form the child nodes of the to-be-constructed node and the to-be-batch data numbers corresponding to the child nodes; and when the next to-be-constructed node exists, determining the batch attribute number of the to-be-constructed node and repeating the above steps. According to the decision model construction method provided by the invention, the data interaction during a multi-platform joint modeling process can be reduced, and thedata confidentiality is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a decision-making model construction method, a decision-making model formed by using the decision-making tree construction method, and a decision-making method using the decision-making model for decision-making. Background technique [0002] Improving the decision-making accuracy of artificial intelligence models requires a large amount of training data. Due to data source channels and cost reasons, it is difficult for a single data provider to meet the demand. Therefore, related model establishment often uses data provided by multiple data platforms. In order to avoid the risk of user privacy leakage caused by the aggregation of large amounts of data on multiple platforms, and the security risks of enterprise and government data leakage, related technologies have proposed a technical solution for the joint modeling tree model of multiple data platforms. [0003] Alt...
