Web6 jan. 2024 · MinHashing is a very efficient way of finding similar records in a dataset based on Jaccard similarity. PyMinHash implements efficient minhashing for Pandas … WebMinHash LSH also supports a Cassandra cluster as a storage layer. Using a long-term storage for your LSH addresses all use cases where the application needs to continuously update the LSH object (for example when you use MinHash LSH to incrementally cluster documents). The Cassandra storage option can be configured as follows:
