关于Johnson-Lindenstrauss引理中的随机性约化

On randomness reduction in the Johnson-Lindenstrauss lemma

Paweł Wolff

摘要:

Ailon和Chazelle(2006)以及Matoušek(2008)提出了所谓的快速Johnson-Lindenstrauss变换的改进。虽然它保留了原始构造的时间效率和实现的简单性,但它减少了用于生成随机变换的随机性。在分析的建设两个辅助结果建立可能是独立的利益:Bernstein型不等式的总和随机样本从一个家庭的独立随机变量和正常的近似结果,这样的总和。

英文摘要:

A refinement of so-called fast Johnson-Lindenstrauss transform, due to Ailon and Chazelle (2006), and Matoušek (2008), is proposed. While it preserves the time efficiency and simplicity of implementation of the original construction, it reduces randomness used to generate the random transformation. In the analysis of the construction two auxiliary results are established which might be of independent interest: a Bernstein-type inequality for a sum of a random sample from a family of independent random variables and a normal approximation result for such a sum.
