A Tale of HodgeRank and Spectral Method: Target Attack Against Rank Aggregation Is the Fixed Point of Adversarial Game. (arXiv:2209.05742v1 [cs.LG])

Rank aggregation with pairwise comparisons has shown promising results in
elections, sports competitions, recommendations, and information retrieval.
However, little attention has been paid to the security issue of such
algorithms, in contrast to numerous research work on the computational and
statistical characteristics. Driven by huge profits, the potential adversary
has strong motivation and incentives to manipulate the ranking list. Meanwhile,
the intrinsic vulnerability of the rank aggregation methods is not well studied
in the literature. To fully understand the possible …
