Complex Network Analysis in Python

Slice Weighted Networks

Lucky network analysts work with unweighted networks. In an unweighted network, all edges are equal. You consider either all of them, and get what you get—or none of them, and get a network with no edges.

Unlucky network analysts work with weighted (and possibly signed) networks. In a weighted network, some edges are strong, and some are weak. If you keep all edges, you will have a distorted view of the network because there are algorithms that do not discriminate edges by weight. For them, an edge with a weight of 1.00 (to your best life-long friend) has the same importance as another edge with a weight of 0.01 (to the guy who takes the same 7:00 a.m. bus, always sits in the back, and reads Alaska Dispatch News). ...
