-Hanny is a Hash-based Approximate Nearest Neighbor (ANN) search library in Ruby.
-Hash-based ANN converts vector data into binary codes and builds a hash table by using the binary codes as hash keys.
-To build the hash table, Hanny uses Locality Sensitive Hashing (LSH) of approximating cosine similarity.
-It is known that if the code length is sufficiently long (ex. greater than 128-bit), LSH can obtain high search performance.
-In the experiment, Hanny achieved about twenty times faster search speed than the brute-force search by Euclidean distance.
