Abstract: A Integrated Pyramid Model is proposed for Single-Class Classification(Single-Class Classification Integrated Pyramid Mode1,SCCIPM). This model is composed of four independent collaborative layers by Comprehensive obtain layer, Assistant j udgment layer, Kernel classification layer and Optimization layer. Comprehensive obtain layer formed by improved KNN and optimized 1-DNF two classification methods,mainly for obtaining negative examples,results are submitted to Assistant judgment layer voting reliable negative examples. Kernel classification layer update reliable negalive examples by several iteration, each iteration establish a classifier. Optimization layer according to Kernel Classificalion layer of different classifiers, optimally select the final classifier. The simulation experiment result indicates that when positive examples arc 50 0 0 of total samples below, SCCIPM shows obvious advantages over other methods in solving the SinglcClass Classification and has good classification performance.
