Simple Constructions of Almost k-Wise Independent Random Variables
We present three alternative simple constructions of small probability spaces on n bits for which any k bits are almost independent. The number of bits used to specify a point in ...

Multi-dimensional Histograms with Tight Bounds for the Error
Histograms are being used as non-parametric selectivity estimators for one-dimensional data. For highdimensional data it is common to either compute onedimensional histograms for ...

Estimating Sum by Weighted Sampling
We study the classic problem of estimating the sum of n variables. The traditional uniform sampling approach requires a linear number of samples to provide any non-trivial guarante...

Practical Variable-Arity Polymorphism
Just as some functions have uniform behavior over distinct types, other functions have uniform behavior over distinct arities. These variable-arity functions are widely used in scr...
