Model interpretation method, apparatus and device, and readable storage medium

Abstract

The invention discloses a model interpretation method, apparatus and device, and a readable storage medium. The method comprises the steps of performing interpretation processing on a model predictionresult of a target user by adopting a preset interpretation algorithm to obtain an interpretation result, generating a plurality of interpretation text contents according to the interpretation result, and analyzing each interpretation text content by adopting an acceptability discrimination model to obtain an acceptability corresponding to each interpretation text content, the acceptability discrimination model being obtained by training feedback data of historical interpretation text contents based on historical users, and selecting a target interpretation text content from the interpretation text contents based on the acceptability and outputting the target interpretation text content. According to the method, the actual application effect of model interpretation is improved.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a model interpretation method, device, equipment and readable storage medium. Background technique [0002] With the rapid development of machine learning, the academic community has proposed a series of high-performance machine learning models, including support vector machines, random forests, gradient boosting trees, and deep learning. The mathematical indicators of these complex models are generally better than simple models such as decision trees and logistic regression, but the internal principles are difficult to understand. However, in many business applications, it is necessary to explain the model, that is, explain why the model outputs a certain prediction result. For example, in the bank credit business, sometimes it is necessary to explain to the rejected person why the loan application is rejected. Model interpretation technology is in the early st...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a model interpretation method, device, equipment and readable storage medium, aiming at solving the problem that the results of the current model interpretation are estimated results, which have a certain degree of credibility, but in actual application scenarios, they are not It must be accepted by the interpreter, that is, the problem that the actual application of the model explanation is not effective
