摘 要:農(nóng)產(chǎn)品價(jià)格直接影響人民的生活水平,研究農(nóng)產(chǎn)品價(jià)格的內(nèi)在規(guī)律和做好農(nóng)產(chǎn)品價(jià)格的預(yù)測(cè)具有重要意義。文章基于引力搜索算法和相關(guān)向量機(jī)理論建立了農(nóng)產(chǎn)品價(jià)格指數(shù)擬合模型。仿真結(jié)果表明,該方法是有效的。

Abstract: The price of agricultural products has a direct impact on people's living standards, so it is of great significance to study the inherent law of the price of agricultural products and to predict the prices of agricultural products. Based on Gravitational Search Algorithm (GSA) and Relevance Vector Machine (RVM), this paper establishes a fitting model of the price index of agricultural products. The simulation results show that the model is effective.
Keywords: price index; Gravitational Search Algorithm; Relevance Vector Machine; Radial Basis Function
