abstract = "This chapter discusses the use of evolutionary
computation in data mining and knowledge discovery by
using intrusion detection systems as an example. The
discussion centers around the role of EAs in achieving
the two high level primary goals of data mining:
prediction and description. In particular,
classification and regression tasks for prediction, and
clustering tasks for description. The use of EAs for
feature selection in the pre-processing step is also
discussed. Another goal of this chapter was to show how
basic elements in EAs, such as representations,
selection schemes, evolutionary operators, and fitness
functions have to be adapted to extract accurate and
useful patterns from data in different data mining
tasks.",
