Super Non-singular Decompositions of Polynomials and their Application to Robustly Learning Low-degree PTFs

Ilias Diakonikolas, Daniel M. Kane, Vasilis Kontonis +2

We study the efficient learnability of low-degree polynomial threshold functions (PTFs) in the presence of a constant fraction of adversarial corruptions. Our main algorithmic resu…

Statistical Query Lower Bounds for Learning Truncated Gaussians

Ilias Diakonikolas, Daniel M. Kane, Thanasis Pittas +1

We study the problem of estimating the mean of an identity covariance Gaussian in the truncated setting, in the regime when the truncation set comes from a low-complexity family $\…
