As noted earlier I am preparing a contribution of Bloom Filter classes to the collections module. As part of this submission there are several methods that operate on BitSets that are used as part of Bloom Filter manipulation and analysis. My question is, should these be contributed as Bloom Filter specific methods or would it be better to submit a BitSet function library.
The methods in question are: hammingDistance() = the cardinality (A xor B) jaccardDistance() = the 1 - jaccardSimilarity() jaccardSimilarity() = cardinality(A xor B) / cardinality (A or B) cosineDistance() = 1 - cosineSimilarity() cosineSimilarity() = cardinality( A and B ) / (Sqrt( cardinality( A ) ) * Sqrt( cardinality( B ))) estimatedLog = estimated log2 of the BitSet if considered a large unsigned int.
