ajst-7347	Li, Xinfang; Huo, Hua	Prediction of PM2.5 Concentration Based on CNN-BiGRU Model	2023	8	.pdf	application/pdf	4143	231	52	Liang Xiguan[15], Kong Yu, et al[16] established a tree model to predict PM2.5, and obtained its strong stability compared to other model tree models. CNN with strong feature extraction capabilities will input output features into the BiGRU network, thereby avoiding the singularity of single model prediction, and improving the prediction ability.	cache/ajst-7347.pdf	txt/ajst-7347.txt
