| 摘 要： | 金属玻璃具有许多独特性能,有着广泛的应用前景,晶化过程对金属玻璃的特性有重要影响.因此提出了一种基于小波变换和AR-ILSSVM金属玻璃晶化过程电特性预测方法.首先利用小波变换将时间序列分解为高频序列和低频序列,利用AR模型预测高频序列,利用ILSSVM方法预测低频序列,预测结果为上述预测的合成.仿真试验表明,这种方法可显著提高时间序列的预测精度.

| Abstract: | The metallic glasses have been widely used in engineering due to their special properties.The process of crystallization has great affects on the properties of metallic glasses.An algorithm for forecasting electrical characteristics of metallic glasses based on wavelet transform and incremental LSSVM was proposed.By wavelet transform,the time series are decomposed into the low frequency series and several high frequency series.The AR models are used to forecast the high frequency series,and the incremental ... |
