A permutation-based model for crowd labeling: Optimal estimation and robustness
The task of aggregating and denoising crowd-labeled data has gained increased
significance with the advent of crowdsourcing platforms and massive datasets. We propose …

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
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 …
