Method and device for generating explanation report of model prediction sample

The invention discloses a method and a device for generating an explanation report of a model prediction sample, relates to the technical field of data analysis, and mainly aims to generate the explanation report corresponding to different input samples of a model while outputting a prediction result. According to the main technical scheme, the method comprises the steps of initializing a featureset of samples, wherein the features of the samples in the feature set are divided into a plurality of categories; traversing features contained in a sample predicted by using a machine learning model, and adding at least part of the traversed features into each category in the feature set according to the category to which the features belong; respectively obtaining text description information corresponding to the sample for each category of features in the feature set according to a preset description specification; and generating an explanation report of the sample based on the obtained text description informatio
