An Optimal Tester for k-Linear [article]

Nader H. Bshouty
2020 arXiv   pre-print
In this paper, we study property testing of the classes k-Linear, the class of all k-linear functions, and k-Linear^*, the class ∪_j=0^kj-Linear.  ...  We then give a non-adaptive distribution-free one-sided ϵ-tester for k-Linear^* that makes the same number of queries and show that any non-adaptive uniform-distribution one-sided ϵ-tester for k-Linear  ...  In the uniform-distribution and distribution-free property testing model, we consider the problem of testing a class of Boolean function C.  ...
