A Separation Between Distribution-Free SQ Learning and Dimension Complexity

Shyamal Patel

We show that there exists a class of boolean functions C such that there is a distribution-independent statistical query algorithm for learning C that makes a polynomial numb…

Distribution-Free Halfspace Testing with Samples

Xi Chen, Renato Ferreira Pinto, Nathaniel Harms +2

We prove a tight lower bound on the number of samples required for testing halfspaces over , in the distribution-free sample-based model where the underlying…

Equivalence of Coarse and Fine-Grained Models for Learning with Distribution Shift

Adam R. Klivans, Shyamal Patel, Konstantinos Stavropoulos +1

Recent work on provably efficient algorithms for learning with distribution shift has focused on two models: PQ learning (Goldwasser et al. (2020)) and TDS learning (Klivans et al.…

Tight Bounds for Learning Polyhedra with a Margin

Shyamal Patel, Santosh Vempala

We give an algorithm for PAC learning intersections of halfspaces with a margin to within error that runs in time $\textsf{poly}(k, \varepsilon^{-1}, ρ^{-1})…

Learning Functions of Halfspaces

Josh Alman, Shyamal Patel, Rocco A. Servedio

We give an algorithm that learns arbitrary Boolean functions of arbitrary halfspaces over , in the challenging distribution-free Probably Approximately Correct (P…

A Mysterious Connection Between Tolerant Junta Testing and Agnostically Learning Conjunctions

Xi Chen, Shyamal Patel, Rocco A. Servedio

The main conceptual contribution of this paper is identifying a previously unnoticed connection between two central problems in computational learning theory and property testing:…

Distribution-Free Testing of Decision Lists with a Sublinear Number of Queries

Xi Chen, Yumou Fei, Shyamal Patel

We give a distribution-free testing algorithm for decision lists with queries. This is the first sublinear algorithm for this problem, which sh…

New Lower Bounds for Adaptive Tolerant Junta Testing

Xi Chen, Shyamal Patel

We prove a lower bound for adaptively testing whether a Boolean function is -close to or -far from -j…

Threshold Graphs Maximize Homomorphism Densities

Grigoriy Blekherman, Shyamal Patel

Given a fixed graph and a constant , we can ask what graphs with edge density asymptotically maximize the homomorphism density of in . For all f…

A Trivial Yet Optimal Solution to Vertex Fault Tolerant Spanners

Greg Bodwin, Shyamal Patel

We give a short and easy upper bound on the worst-case size of fault tolerant spanners, which improves on all prior work and is fully optimal at least in the setting of vertex faul…
