Abstract

The invention provides an expert system updating method and device, and a business processing method and device. The expert system updating method comprises the steps: acquiring a probability graph network corresponding to at least one reference expert system, wherein the reference expert system and the target expert system are used for outputting a business decision result corresponding to the target business based on the business feature data of the same target business; acquiring the sample business feature data and optimization target data of the target business; and based on the data, combining the probabilistic graph networks of the reference expert system and the target expert system to carry out graph structure learning, and outputting graph structure updating information of the probabilistic graph network of the target expert system. According to the embodiment of the invention, the expert system has the capability of learning the graph structure, and the decision result of the expert system is more accurate.

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...
