Rapid Identification of Calamina Based on Near-infrared Diffuse Reflectance Spectroscopy and PCA-SVM Algorithm
To establish a near-infrared diffuse reflectance spectroscopy(NIRS) identification model for crude products
counterfeit products and processed products of Calamina by principal component analysis(PCA) and support vector machine(SVM) algorithm.
Method:
2
NIRS of crude products
counterfeit products and processed products of Calamina were collected
the characteristic spectrum segments were selected
the preprocessing method and the optimum principal component number were optimized
and the PCA-SVM qualitative model was established.
Result:
2
The characteristic spectrum segment of analysis model was 7 500-4 000 cm
-1
.Spectra were preprocessed by the first-order derivative method(FD). The optimum principal component number was 5. And the optimum internal parameters of SVM[penalty factor(
c
)=0.25 and kernel function parameter(
g
)=8] were screened by applying the grid search algorithm.In the PCA-SVM qualitative model
the prediction accuracy rate was 100%for the 5-fold cross validation
and the prediction accuracy rates also were 100%both for training set and test set.
Conclusion:
2
PCA-SVM analysis model of NIRS for Calamina samples has a high prediction accuracy rate
and it can be used for the rapid and nondestructive identification of crude products
counterfeit products and processed products of Calamina by combining the diffuse reflection technique on solid powder.
