Abstract EN
A method is proposed for rubber identification based on terahertz time-domain spectroscopy (THz-TDS) and support vector machine (SVM).
In order to improve the accuracy, the cuckoo search algorithm (CS) is used to optimize the penalty factor C and kernel function parameter g of SVM.
The SVM model optimized by the cuckoo search algorithm is abbreviated as CS-SVM.
Principal component analysis (PCA) is applied to decrease the dimension of the spectral data.
The top ten principal component factors, whose accumulated variance contribution rate reaches 93.93%, are extracted from the original spectra data and then are applied to CS-SVM.
The identification rate of testing sets for CS-SVM is 100%, which is significantly higher than 96.67% identification rate of testing sets for PSO-SVM and Grid search.
Experimental results show that CS-SVM can accomplish nondestructive identification for different rubber.
This method lays a theoretical foundation for the application of terahertz spectroscopy in rubber classification and identification.
