基于REMCC-BPNN的粮食产量预测研究
Study on Prediction for Grain Yield Based on REMCC-BPNN
摘要
Abstract
Accurate prediction of grain yield has a great significance for food safety and social stability. An improved Back-propagation Neural Network (BPNN) model named REMCC-BPNN for time series forecasting was proposed. REMCC-BPNN optimizes the training model for BPNN based on the minimum correlation coefficient of the absolute value of the K nearest neighbor training samples' fitting relative error and the K training samples' time order. Two real-world datasels, the grain yield from 1985 to 2011 in China and the grain yield from 1995 to 2010 in Hunan, China, was used to test the effectiveness of REMCC-BPNN. The results showed that the prediction accuracy of REMCC-BPNN is better than that of several frequently-used prediction models for time series, such as BPNN, SVR, ARIMA and GM( 1 ,N). The REMCC-BPNN prediction model is faster and more stable.关键词
