Active ranking of experts based on their performances in many tasks

EM Saad, N Verzelen… - … Conference on Machine …, 2023 - proceedings.mlr.press
We consider the problem of ranking n experts based on their performances on d tasks. We
make a monotonicity assumption stating that for each pair of experts, one outperforms the …

Optimal rates for ranking a permuted isotonic matrix in polynomial time

E Pilliat, A Carpentier, N Verzelen - Proceedings of the 2024 Annual ACM …, 2024 - SIAM
We consider a ranking problem where we have noisy observations from a matrix with
isotonic columns whose rows have been permuted by some permutation π*. This …

A heuristic for statistical seriation

K Dhull, J Wang, NB Shah, Y Li… - Uncertainty in Artificial …, 2021 - proceedings.mlr.press
We study the statistical seriation problem, where the goal is to estimate a matrix whose rows
satisfy the same shape constraint after a permutation of the columns. This is a important …

Contributions to ranking problems and high-dimensional change-point detection

E Pilliat - 2023 - theses.hal.science
This thesis explores two areas in modern statistics: ranking problems and change-point
detection. Both topics are investigated within the framework of high-dimensional statistics …
