Classification of geoelectric structures using time-domain electromagnetic method based on response curve clustering
In this study,we aimed to make full use of the characteristic information carried by the forward response curve in the time-domain electromagnetic method to quickly and accurately predict the types of geoelectric structures.We developed the curve distance by combining the characteristics of distribution and morphology of the curve,and used the correlation coefficient as the weighting parameter to measure its degree of similarity.This enabled us to cluster the forward response curve of the time-domain electromagnetic method.The results of its application showed that the outcomes of clustering obtained by this method could be used to label the forward response samples,and to subsequently classify geoelectric structures by using a multi-classification neural network.
