Robust regression with covariate filtering: Heavy tails and adversarial contamination
Ankit Pensia, Varun Jog, Po-Ling Loh
We study the problem of linear regression where both covariates and responses are potentially (i) heavy-tailed and (ii) adversarially contaminated. Several computationally efficien…
Outlier Robust Mean Estimation with Subgaussian Rates via Stability
Ilias Diakonikolas, Daniel M. Kane, Ankit Pensia
We study the problem of outlier robust high-dimensional mean estimation under a finite covariance assumption, and more broadly under finite low-degree moment assumptions. We consid…
Optimal Lottery Tickets via SubsetSum: Logarithmic Over-Parameterization is Sufficient
Ankit Pensia, Shashank Rajput, Alliot Nagle +2
The strong {\it lottery ticket hypothesis} (LTH) postulates that one can approximate any target neural network by only pruning the weights of a sufficiently over-parameterized rand…
