Estimating and sampling graphs with multidimensional random walks

Abstract: Estimating characteristics of large graphs via sampling is a vital part of the study of complex networks. Current sampling methods such as (independent) random vertex and random walks are useful but have drawbacks. Random vertex sampling may require too many resources (time, bandwidth, or money). Random walks, which normally require fewer resources per sample, can suffer from large estimation errors in the presence of disconnected or loosely connected graphs. In this work we propose a new m-dimensional random … Show more

“…In this paper we consider six sampling methods (see Table II): 1) random-walk sampling (RW) [8]; 2) random-walk sampling with uniform restarts (RWJ and RWU) [8]; 3) frontier sampling (FS) [9]; 4) expansion sampling (XS) [10]; 5) adjusted expansion sampling (AXS); and 6) randomized expansion sampling (RXS). The first four methods are described in [8], [9], [10].…”
