Risk Degree of Earthquake Secondary Geological Hazards Evaluation Method Based on Parameters Optimization of SVC

According to the characteristics of the complexity and variability of factors,a risk degree of earthquake secondary geological hazards evaluation method was proposed based on GA、PSO and K-CV optimized parameters of support vector classification.The method not only has the excellent characteristics of fast solving speed and describing nonlinear relationship of SVC easily,but also has the characteristic of fast optimization.GA、PSO and K-CV were used to search the optimum parameters of SVC,then the optimal model was applied to evaluate the risk degree of earthquake secondary geological hazards.The results show that the method is reasonable and feasible.
