Firstly, the research on the sequence database was introduced. Secondly, the abnormal mining model based on incomplete data and the filling algorithm of mixed missing was introduced, with the filling effect analyzed. Finally, the algorithm was used, the results are analyzed, and the abnormal mining algorithm was improved.
