该文章从混沌和分形的关系出发，基于奇异吸引子的分形结构和时间序列的自仿射特性，提出了一种混沌时间序列的预测方法。采用迭代函数系统跟踪混沌的局部运动轨迹，由此确定统计意义上放射性能最优的时间序列段，并分局吸引子定力和拼贴定理建立预测模型。-This article from the chaos and fractal relationship starting, based on the characteristics of self-affine fractal structure and time sequence of strange attractor, a chaotic time series prediction method. Iterated function systems chaotic local trajectory tracking radioactive energy optimal time sequence segment, thereby determining the statistical significance and branch attractor anyone, and collage theorem to establish prediction model.
