The invention discloses a multi-category
feature selection method for independent inspection of
category specific conditions. The method comprises the following steps: step 1, data preprocessing and category division; 2, class specific condition independence testing is carried out; step 3, carrying out class specific Markov
Blanket discovery, and carrying out class specific Markov
Blanket discovery; step 4, carrying out Markov
Blanket structure optimization, and carrying out Markov Blanket structure optimization; step 5, carrying out cross integration on the class specific features; 6, training and verifying the model; according to the method, a class-specific condition independence test method is adopted, a sample subset is independently constructed for each class, and the condition dependence intensity is calculated, so that statistical deviation caused by inter-class data distribution difference is effectively avoided. By accurately capturing a correlation structure only existing in a specific category, a condition independence test result is more fit with a
real structure of data, and the resolution is remarkably improved.
