摘　　要：Extracting implicit anomaly information through deformation monitoring data mining is highly significant to determining dam safety status.As an intelligent singular value diagnostic method for concrete dam deformation monitoring, shallow neural network models result in local optima and overfitting, and require manual feature extraction.To obtain an intelligent singular value diagnosis model that can be used for dam safety monitoring, a convolutional neural network (CNN) model that has advantages of deep learning (DL), such as automatic feature extraction, good model fitting, and strong generalizability, was trained in this study.An engineering example shows that the predicted result of the intelligent singular value diagnostic method based on CNN is highly compatible with the confusion matrix, with a precision of 92.41%, receiver operating characteristic (ROC) coordinates of (0.03, 0.97), an area-under-curve (AUC) value of 0.99, and an F1-score of 0.91.Moreover, the performance of the CNN model is better than those of models based on decision tree (DT) and k-nearest neighbor (KNN) methods.Therefore, the intelligent singular value diagnostic method based on CNN is simple to operate, highly intelligent, and highly reliable, and it has a high potential for application in engineering.Extracting implicit anomaly information through deformation monitoring data mining is highly significant to determining dam safety status.As an intelligent singular value diagnostic method for concrete dam deformation monitoring,shallow neural network models result in local optima and overfitting,and require manual feature extraction.To obtain an intelligent singular value diagnosis model that can be used for dam safety monitoring,a convolutional neural network(CNN)model that has advantages of deep learning(DL),such as automatic feature extraction,good model fitting,and strong generalizability,was trained in this study.An engineering example shows that the predicted result of the intelligent singular value diagnostic method based on CNN is highly compatible with the confusion matrix,with a precision of 92.41%,receiver operating characteristic(ROC) coordinates of(0.03,0.97),an area-under-curve(AUC) value of 0.99,and an F1-score of 0.91.Moreover,the performance of the CNN model is better than those of models based on decision tree(DT) and k-nearest neighbor(KNN) methods.Therefore,the intelligent singular value diagnostic method based on CNN is simple to operate,highly intelligent,and highly reliable,and it has a high potential for application in engineering.
