This invention discloses a privileged learning classification method based on category awareness and
interpretability guidance, belonging to the field of
artificial intelligence and
machine learning. The method includes: first, dividing the training data into a privileged set containing complete information and a non-privileged set containing only source domain features; for a specific category, extracting feature importance through
interpretability analysis and sparsifying it to generate a category-
specific weight vector; then, calculating the weighted similarity between non-privileged samples and similar samples in the privileged set based on this weight vector, retrieving and transferring the privileged features of the best-matching sample as reconstructed features, and dynamically assigning confidence coefficients negatively correlated with similarity; finally, fusing real and reconstructed privileged features to construct a joint optimization objective function with an adaptive penalty mechanism for confidence coefficients for model training. This invention effectively improves the classification accuracy and robustness of the model in scenarios where some privileged information is missing.
