On the Weakenesses of Correlation Measures used for Search Engines' Results (Unsupervised Comparison of Search Engine Rankings)
Search Engines Correlation Measures Search Engine Rankings

The correlation of the result lists provided by search engines is fundamental and it has deep and multidisciplinary ramifications. Here, we present automatic and unsupervised methods to assess whether...
A survey of results on random random walks on finite groups
random walk finite group Upper Bound Lemma Fourier analysis
2009/5/18
A number of papers have examined various aspects of ``random random walks'' on finite groups; the purpose of this article is to provide a survey of this work and to show, bring together, and discuss s...
Asymptotic results for empirical measures of weighted sums of independent random variables
Asymptotic results empirical measures weighted sums independent random variables

We investigate the asymptotic behavior of weighted sums of independent standardized random variables with uniformly bounded third moments. The sequence of weights is given by a family of rectangular m...
