abstract = "Artificial intelligence theory is extensively employed
in fault diagnosis, as the frequently used
technologies, expert system and neural network, have
their inherent disadvantages that have poor
expansibility and unknown black box structure. Genetic
Programming (GP), an improved evolution algorithm based
on Genetic Algorithm (GA), could offset these
insufficient for its explicit structure. Combining the
main idea of hierarchical clustering, a new method
based on GP is proposed. In this method, the
multi-cluster problem is divided to many two-cluster
problems, and GP serves as a classifier in two-cluster
problem. Generally, the multi-level genetic programming
classifier is expected to simplify the structure and
improve the expansibility of classifier, and its
effectiveness is proved in simulation experiment.",
