Learning with Clustering Structure

no code implementations16 Jun 2015 Vincent Roulet, Fajwel Fogel, Alexandre d'Aspremont, Francis Bach

We study supervised learning problems using clustering constraints to impose structure on either features or samples, seeking to help both prediction and interpretation.

SerialRank: Spectral Ranking using Seriation

no code implementations NeurIPS 2014 Fajwel Fogel, Alexandre d'Aspremont, Milan Vojnovic

Intuitively, the algorithm assigns similar rankings to items that compare similarly with all others.

Spectral Ranking using Seriation

no code implementations20 Jun 2014 Fajwel Fogel, Alexandre d'Aspremont, Milan Vojnovic

We first show that this spectral seriation algorithm recovers the true ranking when all pairwise comparisons are observed and consistent with a total order.

Convex Relaxations for Permutation Problems

no code implementations NeurIPS 2013 Fajwel Fogel, Rodolphe Jenatton, Francis Bach, Alexandre d'Aspremont

Seriation seeks to reconstruct a linear order between variables using unsorted similarity information.
