An information-based network approach for protein classification

Fig 2

Impact of the threshold on protein network connectivity.

This figure shows the line plots of the connectivity values against different multiplicities of the threshold (0.7 ≤ c ≤ 0.9). The connectivity value is expressed as , where 27 is the number of the powered adjacency matrices Aⁿ in series, and n is the power from 1 to N-1 (N = 28 is the number of nodes in the network), and a_n,ij is the ij-th element of the power n adjacency matrix Aⁿ. Nodes i and j are considered in the same connected component if . This graph presents a sample analysis of five primate species (Gibbon, Sumatran Orangutan, Bornean Orangutan, Pygmy Chimpanzee and Chimpanzee). The multiplicity c is varied from 0.7 to 0.9.
