Are all connections meaningful? This image visualizes a new algorithm (known as "network deconvolution") for detetermining important relationships in complex networks. Like a filter on a camera lens, it reveals which links (lines) between interconnected elements (points) are most essential. As the lens passes over each network area, indirect links disappear and direct links become visible. Already tested on large networks mapping gene regulation, protein folding, and academic co-authorship, network deconvolution can be used to identify key drivers of biological, social, and technological systems.
