With a raw flow, we can have flows going both from \(v\) to \(w\) and flow going from \(w\) to \(v\). In a net flow formulation however, we only keep track of the difference between these two flows. Net flow is a function that satisfies the following conditions: A talent flow network is a firm-level social network that is shaped by the movement of talent across organizations ( Dokko and Rosenkopf, 2010 ). In this type of network, the nodes represent individual firms and the connecting lines between the nodes represent the movement of talent among firms.

In our previous example, the flow was 19. Consider the flow across the cut Vs = {s, a, b}. We have three forward edges with flows of 8, 4, and 15 and two backward edges with flows of 1 and 7. Summing, we have 8+4+15-1-7 = 19, as desired.GC-Flow is Both a Generative Model and a GNN. GC-Flow is a normalizing flow. Similar to other normalizing flows, each constituent flow preserves the feature dimension; that is, each Fi is an Rn×D → Rn×D function. Further-more, we let Fi act on each row of the input argument X(i) e separately and identically.The Evolution of Network Flow Monitoring, from NetFlow to IPFIX. Jul 8, 2020.
