Abstract

This specification provides an update method of an expert system, a business processing method and a device, wherein the update method of the expert system includes: obtaining a probability graph network corresponding to at least one reference expert system, and the reference expert system and the target expert system are used based on The business feature data of the same target business outputs the business decision results corresponding to the target business; obtains the sample business feature data and optimized target data of the target business; based on the above data, combines the reference expert system and the probability graph network of the target expert system for graph structure learning, Outputs graph structure update information for the target expert system's probabilistic graph network. The embodiment of the present specification enables the expert system to have the ability to learn the graph structure, which is beneficial to more accurate decision-making results of the expert system.

Description

technical field [0001] This specification relates to artificial intelligence technology, in particular to an updating method of an expert system, a business processing method and a device. Background technique [0002] For business scenarios dominated by manual decision-making, it is usually necessary to conduct logical deduction based on the business data in the business scenario and the manual experience of the leader (also called a domain expert), and finally obtain the business decision result in this scenario. Most of these scenarios have the characteristics of small samples and high sample imbalance. For example, in the credit approval field scenario, the credit bad debt rate is low, there are few negative samples, and the number of historical samples in the scenario is also limited. This makes traditional supervised algorithm models difficult to use in this human-decision-dominated business scenario. [0003] Therefore, in related technologies, evaluation and decisio...
