基于支持向量机和BP神经网络法的地震与爆破事件的自动识别
Automatic identification of earthquake and blasting events based on support vector machines and BP neural network methods
摘要
Abstract
This paper aims to identify,compare,and analyze the natural earthquake and artificial blasting events recorded by three seismic stations of the Uga River,Uligi,and Ceke under the jurisdiction of the Bayannur Earthquake Monitoring Center Station.Firstly,the selected seismic records of earthquake and blasting events are decomposed using the wavelet base functions of sym6,db7,and rbio1.5 by SWT,DWT,and WPT,and the corresponding approximation coefficients and detail coefficients are obtained after decomposition.Then,the energy ratio,energy entropy,and Shannon entropy of each layer are extracted and used as characteristic parameters individually,in pairs,and combination.Finally,the BP neural network and support vector machine(SVM)are used to train the feature parameters,and the recognition model suitable for the central station is determined by training and comparing the recognition rate of the two methods.The analysis results show that the support vector machine is more suitable for the Bayannur station,and its recognition rate reaches 95%.关键词
