Learning Intersections of Two Margin Halfspaces under Factorizable Distributions

Ilias Diakonikolas, Mingchen Ma, Lisheng Ren +1

Learning intersections of halfspaces is a central problem in Computational Learning Theory. Even for just two halfspaces, it remains a major open question whether learning is possi…

Algorithms and SQ Lower Bounds for Robustly Learning Real-valued Multi-index Models

Ilias Diakonikolas, Giannis Iakovidis, Daniel M. Kane +1

We study the complexity of learning real-valued Multi-Index Models (MIMs) under the Gaussian distribution. A -MIM is a function that depends only…

Faster Algorithms for Agnostically Learning Disjunctions and their Implications

Ilias Diakonikolas, Daniel M. Kane, Lisheng Ren

We study the algorithmic task of learning Boolean disjunctions in the distribution-free agnostic PAC model. The best known agnostic learner for the class of disjunctions over $\{0,…

Statistical Query Hardness of Multiclass Linear Classification with Random Classification Noise

Ilias Diakonikolas, Mingchen Ma, Lisheng Ren +1

We study the task of Multiclass Linear Classification (MLC) in the distribution-free PAC model with Random Classification Noise (RCN). Specifically, the learner is given a set of l…

Reliable Learning of Halfspaces under Gaussian Marginals

Ilias Diakonikolas, Lisheng Ren, Nikos Zarifis

We study the problem of PAC learning halfspaces in the reliable agnostic model of Kalai et al. (2012). The reliable PAC model captures learning scenarios where one type of error is…

SQ Lower Bounds for Non-Gaussian Component Analysis with Weaker Assumptions

Ilias Diakonikolas, Daniel Kane, Lisheng Ren +1

We study the complexity of Non-Gaussian Component Analysis (NGCA) in the Statistical Query (SQ) model. Prior work developed a general methodology to prove SQ lower bounds for this…

Near-Optimal Cryptographic Hardness of Agnostically Learning Halfspaces and ReLU Regression under Gaussian Marginals

Ilias Diakonikolas, Daniel M. Kane, Lisheng Ren

We study the task of agnostically learning halfspaces under the Gaussian distribution. Specifically, given labeled examples from an unknown distribution on $\mathb…

Cryptographic Hardness of Learning Halfspaces with Massart Noise

Ilias Diakonikolas, Daniel M. Kane, Pasin Manurangsi +1

We study the complexity of PAC learning halfspaces in the presence of Massart noise. In this problem, we are given i.i.d. labeled examples $(\mathbf{x}, y) \in \mathbb{R}^N \times…
