Abstract
a real-valued representation for the negative
selection algorithm and its applications to anomaly
detection. In many anomaly detection applications, only
positive (normal) samples are available for training
purpose. However, conventional classification
algorithms need samples for all classes (e.g. normal
and abnormal) during the training phase. This approach
uses only normal samples to generate abnormal samples,
which are used as input to a classification algorithm.
This hybrid approach is compared against an anomaly
detection technique that uses self-organising maps to
cluster the normal data sets (samples). Experiments are
performed with different data sets and some results are
reported.
