Decision Fusion System for Bolted Joint Monitoring

Procedure 1

Proposed procedure for classifier selection.

Define:

    is the set of the classifier needed to be selected

    is the set of the classifier selected

    to index the classifier in set

    is the th classifier in set

    is the th classifier in set

    is the accuracy rate of the th classifier in set , which is the ratio of number of samples classified correctly to

   the total samples.

    is the Entropy-base diversity measure between classifier and

Begin:

Step  1. Select the initial evaluation criterion, such as .

Step  2.

Step  3.

   Note, when a similar low correlation degree appears for more than one classifier, the classifier that has the highest

   accuracy rate is chosen.

Step  4. If , then, go to Step  5; otherwise, go to Step  3; end.

Step  5. Find the optimal classifier sequence .
