Graphlet degree vector python

WebJan 1, 2024 · The original graphlet degree vector counts the occurrences of each type of graphlet, and as a result, a one-dimensional vector is created. Here, we propose to construct a two-dimensional vector by counting each type of edge touched by each type of graphlet. To begin with, we give the formal definition of an edge-labelled network. WebApr 28, 2024 · In detail, for each node, the corresponding graphlet degree vector (GDV) is formed by letting its j-th entry equal to the number of times the node “touches” (i.e., belongs to) the orbit O_j. The GDV can be computed by standard software packages, such as ORCA (Hocevar and Demsar, 2014). Many of the entries of the GDV have well-defined ...
