The invention requests to protect a missing label multi-label classification method based on example-level and label-level association, and the method comprises the steps: S1, inputting a feature matrix of a training sample, constructing a feature-based sample neighbor graph through a linear recombination strategy, mining the geometric structure information of the sample, and obtaining an example-level association matrix; S2, inputting a label matrix of a training sample, and constructing a label-based semantic association graph through a low-rank representation method to mine semantic association information of labels to obtain a label-level association matrix; S3, utilizing Laplace manifold regularization to associate and construct the two labels into two regularization items; and S4, constructing an objective function and solving the objective function. According to the multi-label classification method, the relevance of the example level and the label level is combined, and the classification effect of the multi-label classification method can be effectively improved under the condition that the labels are partially lost.
