Objective: In order to accurately and quickly discriminate cigarettes. Methods: After collecting the near-infrared spectra of different brands and reducing the interference factors through the spectral preprocessing method, the spectral pretreatment method, the population number of firefly algorithm (FA) and the number of iterations on the correct rate of cigarette classification were investigated by using firefly algorithm to optimize support vector machine (SVM) parameters. Results: The standard normal variable transformation (SNV) combined with the first derivative method (1D) was used for near-infrared spectroscopy preprocessing. Under the condition that the number of firefly populations was 20 and the number of iterations …
