The above is a very simple example of having a probability classifier output for a binary-class case either 0 or 1 based on some probabilities. In addition it is straightforward how you can change the threshold. You set the threshold either higher or lower of 50% to change the precision/recall balance and thus optimize for your own unique

Intuitively, precision is the ability of the classifier not to label as positive a sample that is negative, and recall is the ability of the classifier to find all the positive samples. The F-measure (\(F_\beta\) and \(F_1\) measures) can be interpreted as a weighted harmonic mean of the precision and recall.

## A weight-adjusted-voting framework on an ensemble of

2. Weight-adjusted-voting framework . The idea of weight-adjusted-voting of classifiers in an ensemble of size three has been proposed in our previous work [].It is summarized as follows: For a given instance, if a classifier, say A, makes a correct prediction while the other two classifiers, say B and C, make wrong predictions, then the classifier A ’s weight is increased and the weights of

classification with the highest index or weight is the one used for payment. This is referred to as index maximization. For example, if a resident qualifies for both the RUG-IV case mix classification RAC, with an index of 1.36, and HC2, with an index of 1.57, the resident would be assigned to the HC2 classification because it has the highest
