Intelligent Coal Classification Method Based on Near-infrared Spectroscopy and Dual-gated High-resolution Network
To address the problem that severe peak overlap and nonlinear coupling in near-infrared spectra make it difficult for traditional models to effectively extract discriminative features and thus limit classification accuracy in coal classification,this study proposes an intelligent classification method based on a dual-gated high-resolution network(DG-HRNet). First,regularized Mahalanobis distance and standard normal variate transformation are combined to remove abnormal samples and improve spectral data quality. Then,Unet is employed as the backbone network,and a dual-gated high-resolution fusion mechanism is introduced to alleviate the loss of weak detailed features in deep networks. Furthermore,an improved atrous spatial pyramid pooling module and a squeeze-and-excitation attention mechanism are incorporated to enable effective modeling of long-range spectral dependencies and adaptive selection of key features. Experimental results show that,in the four-class coal classification task,DG-HRNet achieves an accuracy,precision,recall,and F1-score of 0.961 0,0.964 7,0.958 6,and 0.961 4,respectively,significantly outperforming traditional machine learning models and mainstream deep learning models. This study provides a new technical route for rapid,accurate,and non-destructive coal identification in coal trade and customs supervision.
