摘要
研究数据外推技术中非常重要的带状区域定位方法.数据外推定理给出外推后带状区域的定位方案.指出这个定理给出的只是一个非常粗糙的定位方案,甚至很多情况下是无效的.针对这个问题,提出了基于迭代进行改进的方案.新方案能够更加精确地定位带状区域,并且在适当的假定下对粗糙方案无效的情况也能定位出一个有效的带状区域.实验例子表明了新方案的精确性与有效性.
The locating methods of available bands, which was very important in the data extrapolating technique, were studied. Data Extrapolating Theorem which may offer a method of locating are available band, was proved. Then it is pointed out that current locating methods were very rough and even unfeasible in many cases. Therefore,an iteration-based locating method was proposed,which may locate an available band more precisely and also can locate an available band for cases in which current locating methods fail to work under an appropriate assumption. Examples show the accuracy and effectiveness of the iteration-based method.
