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
