Learning General Halfspaces with General Massart Noise under the Gaussian Distribution

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

We study the problem of PAC learning halfspaces on Rd with Massart noise under the Gaussian distribution. In the Massart model, an adversary is allowed to flip the labe…

Agnostic Proper Learning of Halfspaces under Gaussian Marginals

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

We study the problem of agnostically learning halfspaces under the Gaussian distribution. Our main result is the {\em first proper} learning algorithm for this problem whose sample…

The Optimality of Polynomial Regression for Agnostic Learning under Gaussian Marginals

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

We study the problem of agnostic learning under the Gaussian distribution. We develop a method for finding hard families of examples for a wide class of problems by using LP dualit…
