Tight Bounds for Equivalence Testing with Non-Adaptive Conditional Samples

We study distribution testing with access to non-adaptive conditional samples.

Key points

  • Specifically, we give tight bounds for equivalence testing, determining whether two unknown distributions are equal to or $\varepsilon$-far from each other in total variation distance.
  • Our algorithm and lower bound show that $\tilde Θ\left(\frac{\log n}{\varepsilon^2}\right)$ queries are necessary and sufficient for this problem.
  • These results demonstrate that the complexity of uniformity, identity, and equivalence testing with non-adaptive conditional samples are all $\tilde Θ(\log n)$.
