High-Performance Portable GPU Primitives for Arbitrary Types and Operators in Julia
Emmanuel Pilliat
Portable GPU frameworks such as Kokkos and RAJA reduce the burden of cross-architecture development but typically incur measurable overhead on fundamental parallel primitives relat…
Adaptive Algorithms for Infinitely Many-Armed Bandits: A Unified Framework
Emmanuel Pilliat
We consider a bandit problem where the buget is smaller than the number of arms, which may be infinite. In this regime, the usual objective in the literature is to minimize simple…
On Sparsity and Sub-Gaussianity in the Johnson-Lindenstrauss Lemma
Aurélien Garivier, Emmanuel Pilliat
We provide a simple proof of the Johnson-Lindenstrauss lemma for sub-Gaussian variables. We extend the analysis to identify how sparse projections can be, and what the cost of spar…
Optimal rates for ranking a permuted isotonic matrix in polynomial time
Emmanuel Pilliat, Alexandra Carpentier, Nicolas Verzelen
We consider a ranking problem where we have noisy observations from a matrix with isotonic columns whose rows have been permuted by some permutation *. This encompasses many mo…
Optimal Permutation Estimation in Crowd-Sourcing problems
Emmanuel Pilliat, Alexandra Carpentier, Nicolas Verzelen
Motivated by crowd-sourcing applications, we consider a model where we have partial observations from a bivariate isotonic n x d matrix with an unknown permutation * acting on…
Optimal multiple change-point detection for high-dimensional data
Emmanuel Pilliat, Alexandra Carpentier, Nicolas Verzelen
This manuscript makes two contributions to the field of change-point detection. In a generalchange-point setting, we provide a generic algorithm for aggregating local homogeneity t…
