蔬菜价格波动性大、季节性强,受供求关系、季节、气候等多种因素的影响,蔬菜价格具有高度的非线性、高噪声的属性加大了预测的难度。因此运用基于传统的MSE准则函数应用于蔬菜价格预测的建模,以样本的实际输出和神经网络的预测输出的平方差为误差准则函数,来进行人工神经网络参数学习,通过MSE准则的TSK模糊系统模型来预测蔬菜的价格,最后通过实例验证此方法科学有效。
蔬菜價格波動性大、季節性彊,受供求關繫、季節、氣候等多種因素的影響,蔬菜價格具有高度的非線性、高譟聲的屬性加大瞭預測的難度。因此運用基于傳統的MSE準則函數應用于蔬菜價格預測的建模,以樣本的實際輸齣和神經網絡的預測輸齣的平方差為誤差準則函數,來進行人工神經網絡參數學習,通過MSE準則的TSK模糊繫統模型來預測蔬菜的價格,最後通過實例驗證此方法科學有效。

Vegetable price fluctuates greatly and seasonally. It is influenced by the supply and demand relationship, season, and climate. Vegetable price is difficult to forecast for its high degree of non-linear and high-noise properties. For this reason, the paper applies the traditional MSE guidelines function to vegetable price forecast modeling, makes artificial neural network parameters studying by the Squared-Error of the actual output and the neural network forecast output, forecast vegetable price based on the Mse guidelines TSK fuzzy system, and finally proves that the method is efficient by way of example.
