Variable selection, monotone likelihood ratio and group sparsity
Cristina Butucea, Enno Mammen, Mohamed Ndaoud +1
In the pivotal variable selection problem, we derive the exact non-asymptotic minimax selector over the class of all -sparse vectors, which is also the Bayes selector with respe…

Minimax Supervised Clustering in the Anisotropic Gaussian Mixture Model: A new take on Robust Interpolation
Stanislav Minsker, Mohamed Ndaoud, Yiqiu Shen
We study the supervised clustering problem under the two-component anisotropic Gaussian mixture model in high dimensions and in the non-asymptotic setting. We first derive a lower…
