random amplitude error 中文意思是什麼
random amplitude error
解釋
隨機振幅誤差-
When the load of agriculture and illume is forecasted, the load is decomposed into stationary terms that is not related to meteorologic factors and random term that is related to meteorologic factors by use of wavelet analysis. because the forecasting accuracy of stationary term is higher and the amplitude of random term, although it is difficult to forecast, is smaller, so the impact of forecasting error bringing about by random factors on final forecasting result is weakened
在預測不同行業的負荷時,利用小波分析的方法對農業和照明負荷序列進行分解,然後將頻率較低的部分視為與氣象因素無關的穩定項進行處理,將頻率較高的部分視為與氣象因素相關的隨機項進行處理,由於穩定項預測精度高,隨機項雖較難預測但幅值較小,因此削弱了隨機因素帶來的預測誤差對最終結果的影響。
