accurately SAGE (Serial Analysis of Gene Expression)
data. The high dimensionality of the data, namely the
large number of features, in combination with the small
number of samples poses a great challenge and demands
more accurate and robust algorithms for classification.
The prediction accuracy of the up to now proposed
approaches is moderate. In our approach we exploit the
associations among the expressions of genes in order to
construct more accurate classifiers. For validating the
effectiveness of our approach we experimented with two
real datasets using numerous feature selection and
classification algorithms. The results have shown that our
approach improves significantly the classification
accuracy, which reaches 99%.
