• Classification average accuracy: This indicator describes how accurate the classi-
fier is given the selected feature set. The classification average accuracy can be
formulated as
AvgP erf =

Match(C

where M is the number of times to run the optimization algorithm to select feature
subset, N is the number of points in the test set, C
i
is the classifier output label
for data point i, L
i
is the reference class label for data point i, and M atch is a
function that outputs 1 when the two input labels are the same and outputs 0
when they are different.
• Statistical mean is the average of solutions acquired
