WebSep 11, 2024 · Abstract—This paper introduces “Multi-Level Spherical LSH”: parameter-free, a multi-level, data-dependant Locality Sensitive Hashing data structure for solving the Approximate Near Neighbors... WebUnlike earlier algorithms with this property (e.g., Spherical LSH [1, 2]), our algorithm is also practical, improving upon the well-studied hyperplane LSH [3] in practice. We also introduce a multiprobe version of this algorithm and conduct an experimental evaluation on real and synthetic data sets.

Webapply cross-polytope locality-sensitive hashing (LSH) [2]—a theo-retically optimal LSH family for cosine similarity—to retrieve the NNs for each tuple in sublinear time. Contributions We now underscore our main contributions: •Automation: We propose a novel hands-off blocking frame-work, AutoBlock, that frees users from the tedious and labo- WebDec 21, 2015 · This asymptotically improves upon the previous best algorithms for solving SVP which use spherical LSH and cross-polytope LSH and run in time 2 0.298n+o(n). Experiments with the GaussSieve validate the claimed speedup and show that this method may be practical as well, as the polynomial overhead is small.
