Method Details

GroupIntoHashTables() protected method

Compute LSH hash buckets which will be inserted into hash tables. Each fingerprint will have a candidate in each of the hash tables.

protected GroupIntoHashTables ( byte minHashes, int numberOfHashTables, int numberOfHashesPerTable ) : long[]
minHashes	byte	Min Hashes gathered from every fingerprint [N = 100]
numberOfHashTables	int	Number of hash tables [L = 25]
numberOfHashesPerTable	int	Number of min hashes per key [N = 4]
return	long[]
