  • 摘要:

    成分数据典型相关分析(CCAI)是一种研究多个成分数据变量之间线性相关关系的方法,在经济、管理、地质、化学等多个领域应用广泛。在海量数据背景下,研究如何针对成分数据流展开典型相关建模分析,具有重要的理论意义和实用价值。为此,提出了成分数据典型相关分析的增量方法,通过对增量成分数据的协方差分解,实现对成分数据流典型相关性的精确计算。同时,给出序贯式和并行式2种分块增量算法,可处理多组成分数据的数据流建模问题,序贯式分块增量算法,按照数据流的先后顺序进行计算,并行式分块增量算法可以达到提高计算效率的目的。通过对不同概率分布和样本规模的成分数据流的仿真研究及微博假新闻的实例分析,验证了所提算法相比于传统的非增量算法,在保证计算准确性的前提下,具有提高运算效率的优势。
