Abstract

The invention discloses a model interpretation method and device and a readable storage medium. The method comprises the steps: obtaining to-be-interpreted sample data, and distributing the sample data to all execution units in a cluster; broadcasting a to-be-interpreted model to each execution unit, so that each execution unit calculates the contribution degree of the target sample data to the prediction result of the to-be-interpreted model based on a preset model interpretation algorithm after receiving the to-be-interpreted target sample data. According to the method, the model interpretation efficiency is improved, and the method can be used for processing model interpretation tasks of more complex service scenes.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a model interpretation method, device 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. In many business applications, the interpretability of the model is very important. For example, in the bank credit risk control business, sometimes it is necessary to explain to the rejected person why the loan application is rejected, and the model needs to be interpretable. In addition, an easy-to-understand model is also convenient for modele...
