Here, a variant of the product combining rule of Equation 18 is proposed to address the imbalance problem.
In [24] and [25], the PU activity is modeled as a Markov chain, and the final decision is also based on history observations but using different combining rules from that of [22].
(3) The recognition method of combining rules and statistics.
The rightmost two columns correspond to the two ways of combining rules and machine learning described in the Combining rules and machine learning section.
As the γ values of the individual LS-SVM models were checked cautiously to prevent overfitting and to assure good generalization performance, the combining rules were learnt on 80% of the data of which 30% (that is, folds 6 to 8) were new with respect to the first training phase.
A more detailed illustration of how the following combining rules are applied to the sets of plausible values is provided in Additional file 1.
But if the priori probability is only available to the combiner, but not available to the BPA calculator, the combining rule under the instruction of the priori probability is being studied and will be presented in another paper.
From Tables 2 and 3, one can see that using the proposed product combining rule, the classification accuracies of all the image classes have been improved.
A product of probability combining rule is employed to integrate the multiple classifiers for the prediction of academic performance of the engineering students.
