Model prediction result interpretation method and device

The invention discloses a model prediction result interpretation method and device. The method comprises the steps of obtaining input data of a target model and a corresponding input data prediction result; performing data enhancement based on the input data and a sample set of the target model to generate a plurality of virtual positive samples and virtual negative samples capable of representingthe input data; for each feature dimension, calculating the separability of the virtual positive sample and the virtual negative sample under the feature dimension; screening the features of which the separability meets a preset condition as interpretation features; for each interpretation feature, judging whether the feature value of the input data is matched with an interpretation condition ofthe interpretation feature or not; and determining the explanation characteristics matched with the explanation conditions and the characteristic values of the explanation characteristics as explanation of the input data predi
