Center node: "approximate similarity search under edit distance using locality sensitive hashing"
  Abstract: Edit distance similarity search, also called approximate pattern matching, is a fundamental problem with widespread applications. The goal of the problem is to preprocess n strings of length d to quickly answer queries q of the form: if there is a database string within edit distance r of q, return a database string within edit distance cr of q. A data structure solving this problem is analyzed using two criteria: the amount of extra space used in preprocessing, and the expected time to answer a query. #R##N#Previous approaches to this problem have either used trie-based methods, which give exact solutions at the cost of expensive queries, or embeddings, which only work for large (superconstant) values of c. #R##N#In this work we achieve the first bounds for any approximation factor c, via a simple and easy-to-implement hash function. This gives a running time of $\tilde{O}(d3^rn^{1/c})$, with space $\tilde{O}(3^r n^{1 + 1/c} + dn)$. We show how to apply these ideas to the closely-related Approximate Nearest Neighbor problem for edit distance, obtaining similar time bounds.
