fcis-14568	Zhu, Honggu; Wu, Jiaye	Classification Method for Railway Tunnel Secondary Lining Cold Joint Detection based on CNN-BiLSTM-SVM Model with Improved Hybrid Leader Algorithm	2023	6	.pdf	application/pdf	4417	240	53	As one of the methods of cold joints detection, the principle is that cold joints will change the energy and speed of Rayleigh waves [3], and cold joints are identified based on this characteristic. In the future, the data set can be gradually improved, a better fitness function can be designed, and through cross- validation, better SVM parameters can be obtained, the generalization ability of the model can be improved, and the detection accuracy can be further improved.	cache/fcis-14568.pdf	txt/fcis-14568.txt
