The Design of Multi-fault Classification Based on Huffman Binary Tree

ZHU Xue-dong,HU ping(Nanjing University of Technology,Nnajing 210009,China)  
Based on the analysis of some existing methods of SVM multi2class classification,a multi2class classification based on Huffman binary tree was put forward.This classification used Kernel function which can transfer non-linear into linear to get the clustering functions,then built a Huffman binary tree based on every fault's priority.This method has been used in the fault diagnosis system of excavator.The result indicates that this classification can find not only faults,but the more important faults first.
