Abstract

SHUANGYAN, Yang et al. Automatic Identification of Cigarette Brand Using Near-Infrared Spectroscopy and Sparse Representation Classification Algorithm. J. Braz. Chem. Soc. [online]. 2018, vol.29, n.7, pp.1480-1486. ISSN 0103-5053.  http://dx.doi.org/10.21577/0103-5053.20180019.

A cigarette brand automatic classification method using near-infrared (NIR) spectroscopy and sparse representation classification (SRC) algorithm is put forward by the paper. Comparing with the traditional methods, it is more robust to redundancy because it uses non-negative least squares (NNLS) sparse coding instead of principal component analysis (PCA) for dimensionality reduction of the spectral data. The effectiveness of SRC algorithm is compared with PCA-linear discriminant analysis (LDA) and PCA-particle swarm optimization-support vector machine (PSO-SVM) algorithms. The results show that the classification accuracy of the proposed method is higher and is much more efficient.

Keywords : near-infrared spectroscopy; deep learning; sparse representation classification; non-negative least squares.
