Selective conformal inference with false coverage-statement rate control
Conformal inference is a popular tool for constructing prediction intervals. We consider here
the scenario of post-selection/selective conformal inference, that is, prediction intervals are …

Conformal link prediction to control the error rate
A Marandon - arxiv preprint arxiv:2306.14693, 2023 - arxiv.org
Most link prediction methods return estimates of the connection probability of missing edges
in a graph. Such output can be used to rank the missing edges, from most to least likely to be …
