WebDec 11, 2013 · This structure augments the neighborhood graph with a bridge graph. We propose to exploit Cartesian concatenation to produce a large set of vectors, called bridge vectors, from several small sets of subvectors. Each bridge vector is connected with a few reference vectors near to it, forming a bridge graph. Our approach finds nearest … Webproperty, the search will be stuck at a locally optimal point and has to conduct exhaustive neighborhood expansion to find better solutions. We present a query-driven iterated …

Fast Neighborhood Graph Search Using Cartesian Concatenation

WebIn the core of these applications, lies a common and critical problem: Given a labeled network and a query graph, how to efficiently search the query graph in the target network. The presence of noise and the incomplete knowledge about the structure and content of the target network make it unrealistic to find an exact match. WebDec 11, 2013 · In this paper, we propose a new data structure for approximate nearest neighbor search. This structure augments the neighborhood graph with a bridge … WebIn this paper, we address the approximate nearest neighbor (ANN) search problem over large scale visual descriptors. We investigate a simple but very effective approach, … strep b bacteria pregnancy
