Higher degree sum-of-squares relaxations robust against oblivious outliers
Tommaso d'Orsi, Rajai Nasser, Gleb Novikov +1
We consider estimation models of the form , where is some -dimensional signal we wish to recover, and is symmetrically distributed noise that may be unbounded…

Consistent Estimation for PCA and Sparse Regression with Oblivious Outliers
Tommaso d'Orsi, Chih-Hung Liu, Rajai Nasser +3
We develop machinery to design efficiently computable and consistent estimators, achieving estimation error approaching zero as the number of observations grows, when facing an obl…

Sparse PCA: Algorithms, Adversarial Perturbations and Certificates
Tommaso d'Orsi, Pravesh K. Kothari, Gleb Novikov +1
We study efficient algorithms for Sparse PCA in standard statistical models (spiked covariance in its Wishart form). Our goal is to achieve optimal recovery guarantees while being…
