چکیده

An early-warning indicator screening method is proposed in order to construct an early-warning system for vegetable prices. Through index contribution analysis and the application of a support vector regression algorithm, we compare the results of early warning before and after index optimization. Experimental results show that the proposed early-warning system was significantly improved after indicator optimization by using index contribution analysis.
