Good luck with that. You’d need 1,000 servers just to get the compute time down to a week. But there’s a better way… MinHash Signatures. The MinHash algorithm will provide us with a fast approximation to the Jaccard Similarity between two sets. For each set in our data, we are going to calculate a MinHash signature.

Web1. The problem with these two approaches is that either the space complexity ex-plodes exponentially with d, or the search time rapidly approaches O(n). 2. In particular, VoD of npoints in d-dim can have size (ndd=2e). We need to store the VoD in a point-location data structure, and point location in d-space is also not trivial. 3.
