| Abstract: |
| Combined with the requirement of real project,the statistic concept of believing degree is introduced into feature extraction and a dynamic algorithm for effective feature extraction is proposed,which is based on accuracy requirement and capable of constringing the feature dimension while reducing leaked or pretend alarm probability.The design detail of a note identification system,which adopts the algorithm,and its test results are introduced.The real applications have verified its effectiveness. |
