Abstract: Sampling is a standard approach to big graph analytics. But a good sample need to represent graph properties of interest with a known degree of accuracy. This talk describes a generic tunable sampling framework, graph sample and hold, that applies to graph stream sampling in which edges are presented one at a time, and from which unbiased estimators of graph properties can be produced in post-processing. The talk also describes the performance of the method on various types of graph, including social graphs, amongst others.
