Furthermore, we undertake an analysis of the approximation error of FIM for network inference.

Influence Maximization with Fairness at Scale (Extended Version)

no code implementations2 Jun 2023 Yuting Feng, Ankitkumar Patel, Bogdan Cautis, Hossein Vahabi

In this paper, we revisit the problem of influence maximization with fairness, which aims to select k influential nodes to maximise the spread of information in a network, while ensuring that selected sensitive user attributes are fairly affected, i. e., are proportionally similar between the original network and the affected users.
