Tradeoffs for nearest neighbors on the sphere

  title={Tradeoffs for nearest neighbors on the sphere},
  author={Thijs Laarhoven},
We consider tradeoffs between the query and update complexities for the (approximate) nearest neighbor problem on the sphere, extending the spherical filters recently introduced by [Becker–Ducas–Gama– Laarhoven, SODA’16] to sparse regimes and generalizing the scheme and analysis to account for different tradeoffs. In a nutshell, for the sparse regime the tradeoff between the query complexity nq and update complexity nu for data sets of size n can be summarized by the following equation in terms… CONTINUE READING
