Which approach, Jaccard or Hamming distance, is more similar to the Simple Matching Coefficient, and which approach is more similar to the cosine measure? Explain. (Note: The Hamming measure is a distance, while the other three measures are similarities, but don’t let this confuse you.)
This exercise compares and contrasts some similarity and distance measures.
The Hamming distance is similar to the SMC. In fact, SMC = Hamming
distance / number of bits.
The Jaccard measure is similar to the cosine measure because both
ignore 0-0 matches.
