We decide to carry out a study of feature selection to try
to identify which feature has the greatest effect on our output
variable (academic status). There are a wide range of attribute
selection algorithms that can be grouped in different ways.
One popular categorization is one in which the algorithms
differ in the way they evaluate attributes and are classified as:
filters, which select and evaluate features independently of the
learning algorithm and wrappers, which use the performance
of a classifier (learning algorithm) to determine the desirability
of a subset [15].
